Graph creation suddenly stopped, PLEASE HELP !

[henryd31]

Running 0.8.6g on fc3 with cactid as a poller. The system has been running for 8 months now and all was good. Last night around 10:15PM
all graps stopped being updated. I still get the graphs with values on the description portion being presented (what would appear to be a value of last time it actually ran), but the actual graph stops at 10:15PM last night. All rrd files show as last being updated at 10:15PM, looking at the log the poller seems to be executed properly every fine minutes and all seems to complete properly. Any ideas ???

well, restarted the machine and still no go....tried switching to cmd.php but it times out as i have too much stuff to run...running on cactid 0.8.6e-r7...when the polling start automatically thru cron it seems to be ok...when i run it by hand this is what i get, the rrd files are still not being updated in either case....

There is a more up to date cactid.

Also, run the following query on you cacti database:

Code: Select all

truncate poller_output;

Make sure the poller is not running when you run that query.

Updated to cactid 0.8.6f which didn't seem to do much, then used the truncate command, and this time I can see the rrd files being updated and graphs seem to be coming back...so what's this all about ?

Something went wrong... And the poller_output table had garbage in it.

Typically this happens if a file system fills up or mysql or the poller crashes when polling.

Please check your memory limits for php. If you're just below the limits (defauflt=8MB) and sths going wrong, you're not getting anything out anymore. 64MB is recommended for php/cacti

Looks like I got the same issue again, and doing "truncate poller_output" in mysql resolved it again. So, how do I increase the php memory limits on FC3 ?

Thanks !!

Ok, I edited php.ini and increased the value from 8MB to 64MB.
Bigger question here is whether this is something I simply should have increased or whether there are other issues I need to look into, mainly
whether I should upgrade my system. Since this is running FC3, I have to run it on rather old mysql/php combination:
PHP 4.3.11
Mysql 3.23.58

Tried the upgrade on my backup system to newer versions but it would seem there are just too many dependencies to make a clean upgrade path. As such the only way for me to go would be to find a machine with similar hardware capabilities and get it ready, or redo existing one and after words use backups to restore the data and convert, which will not be easy to have agreed to.

Applying cacti to a freshly installed system should not be that big of a task. It would require dumping the mysql database as told in the upgrading instructions.
Then, you'll have to copy all cacti files (including crontab) to the new cacti system, restore the mysql db and copy all existing rrd files to the new /rra directory. You may want to have a dry run before. The steps above may be repeated several times, until you're sure to not missing anything.
