Hiya,
I have hosts that have about 300 interfaces and yeah, it takes a while
to poll them :)
There is a threaded poller but I have not been able to make this work yet.
Saying that, I have about 2200 interfaces and my CPU load is at 45 on a
duel cpu XEON :(

I'm looking at using jffnms in our network. The interface is great, and
it looks very promising. What I'm stumped on is the performance of the
poller.
To start, I've run autodiscovery against one of our routers, a cisco
6500, and it produces 599 interfaces. poller2.php never completes (it
just times out), and poller.php takes > 5 minutes to poll just that one
host:
10:20:44 : H 2 : Poller End, Total Time: 539131.16 msec.
The machine and network are quite sufficient, I believe. When I run
poller.php manually, it looks to be spending most of its time doing the
snmp queries. A glance at the code looks like it is running snmpget
repeatedly for each OID. Have there been any efforts to rework the
poller to not have this (process forking) overhead?
Are there others running jffnms' poller with a similar number of
interfaces on a single host? If the poller should scale to this size,
can anyone recommend where to look for my performance bottleneck?
Thanks!
