SNMP Get Timeout with empty OID?

[alessandro80]

Hi everyone,

pleased to meet you. I've been using cacti for a while to monitor some HP 1810g and 1800g switches; among them there is one giving me some weird logs and drawing holes in graphs. I tried to debug the problem using the mentioned guide, but unfortunatly i cannot investigate manually the OID manually because there in no OID in the log:

08/08/2012 09:14:06 AM - CMDPHP: Poller[0] Host[3] DS[9] WARNING: Result from SNMP not valid. Partial Result: U
08/08/2012 09:14:06 AM - CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host:'myswitch.example.com', and OID:''

Using cacti 0.8.7h on Ubuntu Linux 12.04 Server x64. I tried incresing timeouts with no luck.

I also get this error sporadically (maybe twice a day):


08/08/2012 03:56:06 AM - POLLER: Poller[0] WARNING: Poller Output Table not Empty. Issues Found: 21, Data Sources: traffic_in(DS[90]), traffic_out(DS[90]), traffic_in(DS[91]), traffic_out(DS[91]), traffic_in(DS[95]), traffic_out(DS[95]), traffic_in(DS[96]), traffic_out(DS[96]), traffic_in(DS[101]), traffic_out(DS[101]), traffic_in(DS[106]), traffic_out(DS[106]), traffic_in(DS[111]), traffic_out(DS[111]), traffic_in(DS[176]), traffic_out(DS[176]), traffic_in(DS[181]), traffic_out(DS[181]), traffic_in(DS[186]), traffic_out(DS[186]), traffic_in(DS[191]), Additional Issues Remain. Only showing first 20

Which i don't know if relates to the problem.


Thanks for the support, a screenshot is attached, but not all ports de facto are showing this issue.

Please see Poller Cache and verify, that the OID is present
