RRDs only updated in irregular intervals

[yellowpaper]

Hello,

for quite some time now the poller seems to work incorrect, seemingly inserting data as he wants to, which looks like that:


After that I checked my log which is giving me following results:

Code: Select all

It's not saying that i was an error or a warning, but it clearly states that its processing a different amount of RRDs from poll to poll but doesnt tell me why. Before I dig into the php code myself I wanted to ask if someone knows what could possibly cause this problem. Btw. I upgraded to 0.8.7i with PIA.

Greetings,

This looks very similar to my problem and your messages actually indicate that you are having 2 crons. Try using this to make sure:

Code: Select all

 grep "poller.php" /etc/cron* -R
