Once again: Poller Output Table not empty

Post by Akven »

Ubuntu 13.10 x64
Cacti 0.8.8b

I had a working graph. But one day it stopped and now I get:

10/31/2013 10:32:02 AM - SYSTEM STATS: Time:1.0352 Method:spine Processes:1 Threads:4 Hosts:25 HostsPerProcess:25 DataSources:217 RRDsProcessed:98
10/31/2013 10:32:01 AM - POLLER: Poller[0] WARNING: Poller Output Table not Empty. Issues Found: 1, Data Sources: bps_in(DS[99])

I tried rebuild_poller_cache.php
I tried poller_output_empty.php
root@cacti:/usr/share/cacti/cli# php -q poller_output_empty.php
There were 0, RRD updates made this pass

No result.

I can't get my graph working.

Where should I look to correct this.
This Poller table thing happens regularly on different graph with no reason. And I can't make them work again until I delete graphs and create them again - but it is not an option.

Please check the debugging documentation in my signature.

Regarding poller time outs, you might be hitting one device which is (sometimes) not responding. Please try to find it by temporarily raising your debugging level and check your log files.

Here is debug log. I can't find any other errors regarding this DS[99].
And it seems everything else working fine.

It seems I resolved my issue by setting higher Poller Interval.
However, there was no sign that it was needed in log.

Well, this is a sign that something is going wrong:

Code: Select all

11/05/2013 07:59:11 AM - POLLER: Poller[0] WARNING: Poller Output Table not Empty. Issues Found: 1, Data Sources: bps_in(DS[99])
And you seem to be polling very often: every ten seconds... You made sure that everything can cope with that?

It is a sign that something going wrong, not an explanation of what exactly is going wrong:)
