Moodle in English: Statistics not working

Bill

Are you getting a specific error or message when you try to look at Administration > Reports > Statistics?

No. I simply get "There is no available data for that combination of course and time period." It doesn't matter what "time period" I select, I get this message.

Ok,

One of the things that I would check first is to ensure that you have the timezone setup in your php.ini. In the Date section find the line ;date.timezone =, you will want to uncomment it by removing the semi-colon from the front of it and set it to the timezone that you have set in Administration > Locations. The line in your ini file should look like this date.timezone ='American/Denver' Make sure that you keep the single quotes or it won't work.

Thanks Scott. However, I can only use a .htaccess file to send php settings to my web host (commercial). So, I tried sending the command date.timezone ='American/Denver' and it took the site down. When I removed the line the site was back up. I don't know what's going on.

I discovered that my Cron job is running statistics. However, they are running for dates about 4th months prior to the current date. Here is a sample my Cron log showing the dates for the Statistics run. Can anyone help me solve this problem. I checked the date (time zone) on my Moodle server and have it correct. See below that the dates are in May and June... not current.

Running daily statistics gathering, starting at 1210482000:

Hi

We're having the same problem at the moment. I know that the statistics reports were working on the 18th September as I used them then. I've just gone to update the report I generated and I get the same error message described previously:

"There is no available data for that combination of course and time period."

Interestingly, if I go back as far as Two Months, the reports all run fine. As soon as I filter for weeks, they give me the error message. When I ran the reports on the 18th September, I went back for Three Weeks.

Any help would be greatly appreciated. I've tried the solutions suggested above to no avail.

We're running 1.9.2 having upgraded from 1.8 over the summer. Incidently, we have two different Moodles, both upgraded over the summer. The reports on both Moodles worked fine on the 18th September and neither work now. They each have a dedicated server and are on separate domains in the network. I'm wondering if it is a problem common to the upgrade?

Hello!

We are having the same problem, statistics from september 20th are not working anymore "there is no data". I have the cron.php not working and have to execute it myself.

Up until then the statistics are all recorded and working perfectly when asked into the system. We are running Moodle 1.8.

They used to work perfectly, until apparently the users table got problems and I had to Repair it, and the table works fine since then; but following to that (I do not know if it is related or not) statistics are not being recorded.

Can anyone help us?

Thanks a lot

We are experiencing a similar thing on our new Moodle 1.9 built over the summer with the addition of 1.8 courses through the backup process.

I can see 4 week old statistics but nothing within the last two weeks, I can see all the logs it's just the statistics that aren't working

Our error message say " Statistics is currently in catchup mode. So far 22 day(s) have been processed and 20 are pending. Check back soon!"

Hope you can help? big grin

Just to chime in- we have not been able to get statistics working, and just upgraded to the latest 1.9.4 build, but still no luck. We would very much appreciate someone helping us figure out why there is nothing to report! We see the cron job does backups:

Backup tasks finished.
Running auth crons if required...
...preventing stats to run, more than 4 hours since scheduled time.
Cron script completed correctly

We're also seeing "There is no available data for that combination of paper and time period." no matter what options are selected. We are using Moodle 1.9.4+ (Build: 20090310), our Stats settings are:

Enabled
Max processing - 6 months
Max runtime - until complete
Days to process - 31
Run at - 23:55pm
User threshold - 0
Max parent categories - 2

I've found a Tracker Issue MDL-16415 which I'm watching and have voted for, take a watch & vote for it - the more votes the higher up the list it goes!!

Hello everyone.

I encountered this same problem a couple of months ago and after a weeks of investigation, I got it to work again. It's the way the cron is scheduled and it's parameters... I posted my detailed fix on another thread and it really seems to help others.

Here is the thread url

http://moodle.org/mod/forum/discuss.php?d=121225

Here it is again:

xxxxxxxxxxxxxxxx

Hello everyone,

I have to respond to this one because I too when through this problem for weeks and I finally got it working since my testing. I feel your pain and hopefully I can help everyone who is encountering the same weird anomaly

Here is what I have done.

1. If you can, first, upgrade your Moodle just in case. The stats query is problematic and could time out. FYI, I did not upgrade so that should ease your mind (I'm running 1.9.2). I heard it was somewhat fixed in 1.9.4 weekly build.

2. If you can, do a DB check on your mdl_stats table to make sure the statistic tables are working properly.

CHECK TABLE `mdl_stats_daily` , `mdl_stats_monthly` , `mdl_stats_user_daily` , `mdl_stats_user_monthly` , `mdl_stats_user_weekly` , `mdl_stats_weekly` , `mdl_log`

You should get something like:

mdl_stats_daily check status OK
mdl_stats_monthly check status OK
mdl_stats_user_daily check status OK
mdl_stats_user_monthly check status OK
mdl_stats_user_weekly check status OK
mdl_stats_weekly check status OK
mdl_log check status OK

3. if there there are errors, reindex/repair the tables or better yet, your entire database based on your index type (MyISAM or InnoDB)

4. Have a look at you config table and if you can reset the values for statsfirstrunlock, statslastdaily, statsruntimestarthour, and statsruntimestarminute to 0. This will force it to start from the beginning. Note that it could take a while depending on how far back your log starts to process the stats (statsfirstrun field). The values are unix/linux timestamp. Here is a page that I have found useful to calculate the dates in human friendly display. Just enter the datetime stamp values:

http://www.onlineconversion.com/unix_time.htm

5. Have a look at your stats admin page and check and uncheck a few times the "include stats" option.

6. Return to your stats admin page and see when the stats is scheduled to run and make a note of it. It's misleading because it does not run at that time you set but rather it runs on the NEXT cron call AFTER THE SCHEDULED DATE you entered. For example if you set your stats to run at 1:30 AM, it won't run at 1:30 AM as you think it should but instead it runs at the next cron call. Now get this, it does not call on the stats to run everytime so it adds more confusion. It only runs randomly and only within an allowable timeframe o it won't take a lot of server processes. Clear as mud? =)

To save everyone's time, let me show you my cron process (assuming that I have the stats schedule to run at 1:30 AM). I do a back up first using MySQL dump just in case.

10 0 * * * mysqldump -u root -pYourPassword --databases yourMoodleDB > /backup/backupMoodle19/yourMoodlebackup.sql
11 1 * * * /usr/bin/php /usr/var/www/moodle/admin/cron.php > /yourHome/name/checklogA.txt
03 2 * * * /usr/bin/php /usr/var/www/moodle/admin/cron.php > /yourHome/name/checklogB.txt

Explanation:

Assumption: Stats scheduled at: 1:30 AM

1. At 12:10 AM, Linux cron executes the MySQL mysqldump program to backup the moodle database) as mysql root user to the /backup/backupMoodle19/ folder as: yourMoodlebackup.sql

2. At 1:11 AM, the Linux cron calls the moodle cron.php script located locally in the server in /usr/var/www/moodle/admin folder and results logged in a text file called checklogA.txt in the user's home directory (/yourHome/name). It is at this call that the stats process should be scheduled and executed at the next cron call (next step number 3).

2. At 2:03 AM, the Linux cron calls the moodle cron.php script a second time located locally in the server in usr/var/www/moodle/admin folder and results logged in a text file called checklogB.txt in the user'se directory (/yourHome/name). It is at this call that the stats process should start executing/building! The log file should tell you that. It's the same as when you see it scroll onscreen via command line.

I hope this helps everyone.

Good luck.

Christopher

I tried Chistopher's solution, but still get this error that the end of http://mysite.org/admin/cron.php

Running auth crons if required...
...preventing stats to run, last execution was less than 20 hours ago.
Cron script completed correctly
Execution took 18.531617 seconds

Can anyone shed some light on this?

I think I solved the Statistics not working issue (at least for me)

1. My site is huge (22000+ users, 3000+ courses). Cron was being called via wget, but I figured it was timing out while executing the cron.php. I ended up calling the cron.php from the command line via:
php /var/www/html/path/to/cron.php

In the crontab, I set my cron to run every 30 mins instead of the initial setting of 5 min.

2. I used Christopher Lawerence's suggestion to force the cronjob to trigger statistics processing, by resetting some values in the database.

I went directly into the database backend and ran the following query:
select * from mdl_config
where name like '%stat%'

I set the following to numerical ZERO (0).
statsfirstrun
statsfirstrunlock
statslastdaily
statslastweekly
statslastmonthly
statslastexecution

I then *disabled* my cron, so that I could manually trigger the cron.php from the command line, in order to monitor it.

Time to manually call the cron from the command line on the webserver.
php /var/www/html/path/to/cron.php

I saw the stats processing....it took a very long time but it became up to date!

Remember to *enable* the cron after this job is complete!!

I will be monitoring it to ensure that it continues to work.

Additional tips on Statistics settings in Admin->Server->Statistics

1. Depending on your site size, stats processing can be extremely resource intensive, I noticed that processor usage was consistently at 100%.
Set MaxRuntime to under 6 hours (not Until Complete - especially if you have a large site!)

2. Run at: You need to know your server inside out for this setting. For example, i have scripts to optimize my database, backup, zip it and transfer it to another server. Based on my hardware logging, these scripts hog memory and i needed to sets my stats to process outside of these periods of heavy activity.
Set your stats processing time when there is the least amount of activity on your site.

I hope this helps. I will update if anything changes.

Cheers,
-n

Yes that is the key..

reset, restart the cron and call the cron more often.

Some may experience a catch up mode so don't worry because the stats are only allowed to run X number of times for a given period and can be db intensive.

One idea you could do (and only if it's feasible) is to have the same db and stats running on a separate moodle instance just for this procedure.

Basic sql statement will do just fine for each field.

update mdl_config
set value = '0',
where id = '231'

* check first to make sure that 231 is statslastdaily and then you can update safely

* > select id, name, value from mdl_config where where id = '231';

> flush privileges;

Did you try running the moodle cron via command line?

output the results to a text file ... something like this and see what the bottom says..

/usr/bin/php /var/www/mysites/moodle/admin/cron.php > /home/elvis/checklog.txt

adjust to the path of your php accordingly ...

Hi Eric.

1. You should disable your cronjob that calls /admin/cron.php(for now)
2. Go back into the database and reset all the values that Christopher mentioned (yes, again). Also make sure that your settings in Admin->Server->Statistics are properly configured.

3. call the cron via php /commandline (the stats should start processing)
4. if your cron.php is called via wget in the crontab, consider changing it to be called via php as with Christoper's example
5. make sure to reactivate the cron only after this job finishes (may take a while depending on the amount of logs to process)

Cheers,
-n

Yes... it's all about timing actually.

You can run it in your case within a 4 hour window timeframe (so it won't take a hit as it's intensive)

Toggle the enable stats (checkbox) in the admin section a couple of times and save it and then try the cron again.

I would even reset the statslastexecution to 0 if possible and don;t worry if it does not do all the days since November because your max days is only 31 days... then it would it another time.

do it manually first...

Some of the values are still 0. Is this correct, should they still be 0?

Hi Eric

Was wondering did you ever get this issue fixed. Im having the same problem.

Need to have a report done on moodle within the next week. I have tried the suggestions above but nothing seems to work.

I have 442 day to process only 96 were done. It stays at 96 all the time.

Looking in the forum archives for the same error message - "There is no available data for that combination of course and time period." - may be useful :

I forgot to add ... wait for at least 4 hours and try the manual call to cron.php again... you can run the stats when you call it again... technically you could but you'll have to change the codebase wink

... which is not a good thing if you have heavy usage

Don't worry because the stats are only allowed to run X number of times for a given period and can be db intensive. wait until the next day or so.

I found that changing statsexecution to zero and statsdaily to 0

then running cron manually is running the stats process ignoring the fact that it had already run in the past 20 hours.

we are on 1.9.5 as well, maybe this is fixed in later versions.

Note: setting stats settings to a bear minimum first to test and make sure it is running correctly then start incrementing the days etc..

My setup

Maximum processing interval = ALL
Maximum run time = 5 hours
Days to Process = 31

My Moodle is a single server installation, OS SLES 10.2 on VMWare. The VMWare hardware went down on 14 April due to lack of memory - and Moodle has not generated statistics since then.

I am using Moodle 1.9.7 +

I tried to followed Christopher and Noveck's solutions above but to no avail. I set all the values mentioned with the exception of 'statsfirstrunlock' to '0'
(statsfirstrun, statslastdaily, statslastweekly, statslastmonthly, statslastexecution)

One thing that concerns me is that my database does not contain 'statsfirstrunlock' as you can see below:

mysql> select * from moodle.mdl_config where name like '%stat%';

| 465 | statslastmonthly | 0 |
| 540 | statsrunning | 1274783833 |
+-----+----------------------------+------------+
17 rows in set (0.00 sec)

I disabled the moodle cron, set Statistics to run for 6 hours and started it manually using php instead of wget.
8hrs later the site was still unusable with mysqld consuming 97% of the CPU so I had to restart MySQL.

The end of the cron output is below:

Running daily statistics gathering, starting at 1271800800:
................ finished until 1271887200: Thursday, 22 April 2010, 12:00 AM (in 5513 s)

................ finished until 1272146400: Sunday, 25 April 2010, 12:00 AM (in 5436 s)
..............error occured, completed 4 days of statistics.
Cron script completed correctly
Execution took 27366.902784 seconds

Strangely even though it claims to have finished 4 days in April - they are not available.
Administration ► Reports ► Statistics still says:

'There is no available data for that combination of course and time period.'

In addition, Stats was set to start at 12:30 AM and between 2:30 and 3AM I received 12 "Insert into log failed at your moodle site" emails.

Any advice will be greatly appreciated.

Heli,

Check your drive space... is it full?

Did you try to reindex the tables? there may be a corruption.

next, go to your moodle admin page and just set the stats to run no more than 1 day at a time. Do it slowly so it could catch up.

Hi Christopher,

Thanks for getting back to me. I have been having MySQL performance problems for a while now - and regular "Insert into log failed at your moodle site" emails.

(also mentioned here http://moodle.org/mod/forum/discuss.php?d=146521 , http://moodle.org/mod/forum/discuss.php?d=113566#p610941)

We have lots of disk space (our database is currently using 1% of space available). I find that tables are frequently fragmented and I optimise them with PHPMyAdmin almost daily. I last ran myisamchk 10 days ago and the XMLDB editor reports no missing indexes.

I am tentatively trying to optimize MySQL following the recommendations of the MySQL Tuner and the Tuning Primer. Currently the main problems encountered are to do with the Joins, Temporary tables and the Query cache.

After MySQL has been up for only 8hrs:

[!!] Joins performed without indexes: 3093
[!!] Temporary tables created on disk: 34% (20K on disk / 58K total)

The Tuning Primer reported that the query cache was 23% fragmented so I have just flushed it - do you think this could be the problem?

Is there anything else I should do? I am very new to this side of Administration so I really appreciate any assistance.

Hi, I acctivated my statistics some time back but I still get the message that there are no stats avaiblable.

I am in Moodle 2.0.2, the table names match the ones mentioned above but not the field names mentioned in the mdl_config that need to be put to 0.

Can anyone help?

FINAL SOLUTION:

to get statistics working 100% follow these steps:

1) open the file : moodle/lib/statslib.php and scroll down around line 90: and comment out the statements from :

if (isset($CFG->statslastexecution) and ((time() - 20*60*60) < $CFG->statslastexecution))

to the statement :

set_config('statslastexecution', time());

the last statement must be included (do not comment it)

2) go to Server->Statistics and enure that:

Statistics are enabled

Max Processing Interval: All

Max Runtime: until complete

Days to Process: (put any large number, for me I put 1000)

Run At: (set the clock for the current time)

and leave other settings as they are.

3) log in as admin and open the URL: /moodle/admin/cron.php

and wait until processing completes (it may take from minutes to several hours depending on site traffic)

4) go to : reports -> statistics -> and choose whatever you want, then submit, then enjoy the graph.

important note: this walkthrough is for people who want to see statistics effect right now, and how the graph and logs will look like, however, it's not a recommended approach for a heavy traffic moodle site.

if you really followed my approach above exactly, the stats must work for you ...

if it did not work, that means, nobody tried to login or use your moodle site at all, that's why there is no stats ...

@Fedora, if your cron.php page has problems finishing some tasks, open admin/cron.php file, and comment lines between two mtrace statements for the same job, you can comment all mtrace statements and leave the mtrace statemtment that belongs to statistics as is, if you do so, when you open the cron page from browser the statistics job will only work and any other cron jobs will be ignored

Rechecked our MOODLE version it is 1.99.10. Statistics has been enabled but processing is not occurring.

Enable statisticsenablestats

Default: No

If you choose 'yes' here, Moodle's cronjob will process the logs and gather some statistics. Depending on the amount of traffic on your site, this can take awhile. If you enable this, you will be able to see some interesting graphs and statistics about each of your courses, or on a sitewide basis.

Maximum processing intervalstatsfirstrun

None1 weeks2 weeks3 weeks1 months2 months3 months4 months5 months6 monthsAll

Default: None

This specifies how far back the logs should be processed the first time the cronjob wants to process statistics. If you have a lot of traffic and are on shared hosting, it's probably not a good idea to go too far back, as it could take a long time to run and be quite resource intensive. (Note that for this setting, 1 month = 28 days. In the graphs and reports generated, 1 month = 1 calendar month.)

Maximum runtimestatsmaxruntime

Until complete30 minutes1 hour2 hours3 hours4 hours5 hours6 hours7 hours8 hours

Default: Until complete

Specify the maximum time allowed to calculate the statistics for one day, bearing in mind that stats processing can put a big load on the server. The maximum number of days processed in one cron can be specified below.

Days to processstatsruntimedays

Default: 31

Specify the maximum number of days processed in each stats execution. When stats are up-to-date, only one day will be processed, so adjust this value depending of your server load, reducing it if shorter cron executions are needed.

Run atstatsruntimestarthour

01234567891011121314151617181920212223:0510152025303540455055

Default: 0:0

What time should the cronjob that does the stats processing start? Please specify different times if there are multiple Moodles on one physical server.

User thresholdstatsuserthreshold

Default: 0

If you enter a non-zero, non numeric value here, for ranking courses, courses with less than this number of enrolled users (all roles) will be ignored

Maximum parent categoriesstatscatdepth

0123456

Default: 1

Statistics code uses simplified course enrolment logic, overrides are ignored and there is a maximum number of verified parent course categories. Number 0 means detect only direct role assignments on site and course level, 1 means detect also role assignments in parent category of course, etc. Higher numbers result in much higher database server load during stats processing.

This is what the stats off admin shows. How can I get to the cron.php files?

Thanks

Tried your suggestion. I have gone through the logs for my course. We are only getting activity report hits, live logs, but no stats still. Our version is 1.99.10.

ok ...

did you try the second suggestion mentioned above, here it is:

"

@Fedora, if your cron.php page has problems finishing some tasks, open admin/cron.php file, and comment lines between two mtrace statements for the same job, you can comment all mtrace statements and leave the mtrace statemtment that belongs to statistics as is, if you do so, when you open the cron page from browser the statistics job will only work and any other cron jobs will be ignored"

if this does not work for you, give me admin access to your moodle site and FTP access to code (in a private message here), and I will run the statistics for you in minutes.

The "FINAL SOLUTION" above worked for me. There is an if, else if, else statement that says

If the last run was less than 20 hours ago -> then dont run
ELSE if it has been more than 4 hours since the scheduled time -> dont run
Else if the above two statments are not true then go ahead and run.

So if the cron job has never been run before it gets caught up in this statement. Simply commenting out the if statement (lines 120-129 in Moodle 2.0 lib/statslib.php) and leaving the statment:

set_config('statslastexecution', time()); /// Grab this execution as last one

un commented, it will run for the first time witout issue. I have yet to test if it will run on its own after the first time if I uncomment the code that I commented.

P.S. I ended up setting up a cron job on my server to handle cron.php

I have logged in as a student, made some quizes and after that ran the statistics. Statistic tables are filled with some data. However, I recieve the Sorry, there is no available data to display as well.

Stack trace:

line 5889 of lib/weblib.php: call to debugging()
line 21 of course/report/stats/report.php: call to print_error()
line 72 of course/report/stats/index.php: call to require()

Anyone got an idea of the problem?

Hi, I am on 2.0.3 and my statistics aren't working.

They are enabled.

I did the DB check and get all the ok's as above (see below):

mdl_stats_daily check status OK
mdl_stats_monthly check status OK
mdl_stats_user_daily check status OK
mdl_stats_user_monthly check status OK
mdl_stats_user_weekly check status OK
mdl_stats_weekly check status OK
mdl_log check status OK

But I do not have the following fields in my DB; statsfirstrunlock, statslastdaily, statsruntimestarthour, and statsruntimestarminute, so I can not change them to 0.

The cron is working as I tried the test /admin/cron.php and get:

"Cron script completed correctly

Execution took 1.177381 seconds"

Can anyone suggest anything?

Thanks

Hi guys,

I am just wondering, my statistics is not working, although I tried out the described solutions.

I thought, that moodle was working just with normal site administration?

Why do I have to tweek php files and manipulate the database entries?

Does this mean, that the statistics functions of moodle are not working?
Statistics is something substantial, but obviously I need to be a php programmer to make it working. Why dont you distribute SW which was tested and is working?

Hi

We are currently running Moodle 1.9.3 on hosting site and it’s been working fine for us over 5 years. Hopefully upgrade over the summer to 2.0.

In the past I was having trouble with my stats not updating/processing and by following this forum I got them running again.

However we got upgraded to a new professional server to improve performance on the site and since then our stats have stopped running. I have followed everything that I did before and I still can’t get this to update.

In Notifications area it states that the cron.php maintenance script has been completed in over 24 hrs. I can run it normally from the address bar admin/cron.php and it will update some stats manually. However the next day the message appears again.

I contacted the hosing company and they say the cron jobs are working.

Here are my cron commands

*/5 * * * * cd '/home2/stcather/public_html/moodle/admin/' ; /ramdisk/bin/php5 -q 'cron.php' > /dev/null ;

They asked me to change it to the following

*/5 * * * * /ramdisk/bin/php5 -q /home2/stcather/public_html/moodle/admin/cron.php >/dev/null 2>&1

Still didn’t make a difference.

Any help appreciated

Have you tried using php rather than php5. In fact try using php rather than * * * * /ramdisk/bin/php5

My php is the latest version but the installer stopped separating the php5 version in some time ago.

Alternatively, try the other version where you so a command line get on the file using (from the 1.9 cron.php script)

wget -q -O /dev/null 'http://moodle.somewhere.edu/admin/cron.php'

OK i have used the following code

wget -q -O /dev/null 'http://ouraddressinhere/admin/cron.php'

the message that kept on appearing every day regarding the maintence script hasn't ran in 24hours is gone.

and im starting to get backup summary emails again which is a good start. However my stats still will not update. I have just changed the Maximum processing interval to the last 4 months as it was set to all.

However when i click on stats on a user profile i get the following message.

Statistics is currently in catchup mode. So far 161 day(s) have been processed and 47 are pending. Check back soon!

I check back on this tomorrow to see if it changes

Hello,

Thank you for the solutions, I followed the steps and statistics seems to work fine.

However, I can see course statistics only for the last month. Is there any chance to have them for the last 3 months, for exemple?

I set statsfirstrun to 4 months, statsruntimedays to 120 but when I go to the statistic page the statistics shown are limited to 4 weeks. We are working on 2.0 version.

Thank you.
