This is probably because you're polling through a firewall which has session or other rate limits.

Hello Mike,

I've tried to setup observium with rrdcache but the polling stop working after apply configuration. However, permissions seems to be fine.

Nevertheless, when i've running poller.php -d -h myswitch" and got snmp timeouts but when run same command through command line works fine.

CMD[/usr/bin/snmpbulkwalk -Cr'100' -v2c -c *** -Pu -OQUs -m IF-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'********':'161' ifXEntry]

CMD EXITCODE[1]
CMD RUNTIME[2.0631s]
STDOUT[

]
STDERR[
Timeout: No Response from udp:********:161
]
SNMP STATUS[FALSE]
SNMP ERROR[#1002 - Request timeout]

I've a lot of switch with same IOS and same module but just two of them are with this behavior.

Any idea?

Best Regards,

Hi Wilbert

I have a 4 Core with HT Xeon E3 1270 CPU @ 3.5Ghz
32GB Ram

Then 3 Raid 1 Arrays on Fast SSD Drives
1 for System, 1 for MySQL and 1 for RRD

The RRD one has to be on a Enterprise SSD which can handle big amounts of writes (several 10GB/5min)
else it will get broken very fast. To reduce writes on the SSD I also recommend using rrdcached.

Regards

Matthias

What would be your recommendation the cpu, memory, hard disk since it is estimated to have up to 1500 devices?

Wilbert.
