Graphing discontinuous

wysun · Post by **wysun** » Fri Apr 11, 2008 2:45 am

The cpu graph was generated but obviously the information was discontinuous. Maybe during that time, cacti cannot collect any information by snmp protocol. In this graph, there's no graph generated about two hours. I have reboot the cacti server, but the problem existes yet. Hareware of server: PIII 1.0G, memory:2G, Fedora 8. cacti: the latest version. Maybe hardware can not afford this function? But I have another server which hardware is the same as this one, it works well. Is there anyone can help me to solve this problem. I am very appreciate for your help.

Thanks for your quickly response. I have changed the poller to spine, and have nothing others changed. It seems that the graphing is OK now. I will continue to observe it. If the problem still exists, I will come back here to looking for your help. Thanks.

I am also having this issue. I am using spine and have read through all the topics in the "Debugging NaN's in your graphs". I am still stumped.

I'm doing 1 minute polling with cron set to run */5. The issue is sporadic and I can't see any pattern to it...

Hi,hmblprogrammer:

Maybe you can use 5 minute polling with cron set to run*/5 or 1 minutes polling with */1.

I'm confused... I thought I read that the cron job was supposed to stay at every 5 minutes, and if my polling interval was 1 minute the poller would run 5 times?

After I disabled other plugins such as "Monitor"/"thold", the problem didn't occur again, and the graphing is continuous now. You can consider to do so.

I don't believe I have either of those plugins... I just checked and don't see them anywhere. Where would I find them?

Could it be a problem that the system running cacti also runs Nagios?

I just checked my log, this is new... now I see messages like this:

04/16/2008 08:40:18 AM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '60' seconds, with a maximum of a '300' second Cron, but 593 seconds have passed since the last poll!

How do I fix these issues?
