Mikrotik RouterOS, if that helps. Should have mentioned that in the original email, apologies.

If I remember correctly, we use bulkwalk by default unless it's blacklisted by the OS type, if we saw it didn't fully support it...

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.
