Observium uses bulk walk for some things, you might take a look at the max-reps value.  Change it on a per-device basis perhaps.  Troll through the /observium/includes/defaults.inc.php file to see some things you might want to pepper into your config.php.

I’m probably missing something really obvious, but how do you get Observium to use bulkwalk instead of walk?  Currently using revision 4586.

Trying to get poller times down, running:

poller.php  -h 51 –d

to debug, and it sticks on this command:

/usr/bin/snmpwalk -v2c -c 'COMMNAME' -OQUs -m IF-MIB -M /opt/observium/mibs 'udp':'x.x.x.x':'161' ifXEntry

Which makes sense, as there’s an awful lot of interfaces on that particular device.

Running that command manually, using time, gives me:

real    2m35.743s

user    0m0.326s

sys     0m0.168s

Replacing /usr/bin/snmpwalk with  /usr/bin/snmpbulkwalk and running again gives me:

real    0m14.914s

user    0m0.080s

sys     0m0.038s

I’d much rather have this take 15 seconds than 110.  I could have sworn I saw something somewhere about setting some different snmpwalk flags, but I can’t find anything in the docs, the faqs, the archives, the googles.  But it’s Friday, so, again, I’m probably missing something obvious.

Thanks.
