RRDs do net get processed

Post by theflow »

Hey,

I constantly saw the poller.php running for a few days and on last sunday I killed it because I tought it was hung. Since then the graphs are empty and the RRDs are not updated (last modified time is exactly sunday at that time).

I didn't change anything since sunday and I triple checked permissions and settings. I've updated rrdtool, snmpd and cacti to the most recent versions (running on FreeBSD 4.11, php 4.4.0). I have no idea what could be wrong.

here is the output from running poller.php

Code: Select all

I am curious why RRDsProcessed is 0 and nothing is shown about rrdtool updates in the log.

Eearlier I got

CMDPHP: Poller[0] ERROR: Either there are no items in the cache or polling is disabled

But I do not see that anymore

Any help would be appreciated.

thanks,
Florian

Increate your maximum memory to something like 64m in the php.ini file. Then, you should give the poller 1 more opportunity to correct itself. The issue you are having is that your poller_output table is too large to be returned properly.

I am looking at a MOD to fix this. However, today, if you want it fixed you will either have to run once more with more PHP memory or perform the following steps, which will cause data loss.

mysql -u root -p cacti
> truncate table poller_output;
> quit

Hi,

thanks for your quick reply.

the poller_output table is currently empty and is empty in every database backup I have. So truncating does not help here :(

Please run "php poller.php" from the cacti web root in LOW. Post the output.

Okay, I've found it. The database had some serious issues with mysql collations and the join on line 248 in lib/poller.php didn't work and threw a sql error.

I probably know the reason for the collation problems, but why isn't there some better error reporting on mysql queries?
