Onderwerp: [jffnms-users] Poller2 Questions
I've been watching the load level on my polling machine. (I have a
separate Database/Web server, this machine only handles the polling
processes).
The polling machine is a dual 2 GHz Xeon with 1 Gig Ram and 4x 74Gig
10,000 RPM Raptor Drives in a Raid 10 configuration.
I'm monitoring 46 hosts and 1039 interfaces and my processor load level
is at .78 on a 5 minute average, .60 on a 15 minute average.
My first question is: Is this normal for this type of server to be
running this hot? I have another 50 - 100 hosts (1000-2000 interface)
that I want to monitor and I'm not sure if it's going to be able to take
the load.
My next question is about the Poller2 process. What is normal operation
for this process.
I'm seeing a master poller process running and then every minute it
looks like another starts and then exits.
The child poller processes never seem to exit either so I can't tell if
the polling actually completes every 5 minutes or if that's the reason
for the high load level.
Is there a way to tell if the poller made it's rounds within 5 minutes?
Also, before I split up the Poller and Database/Apache machines I did
some figuring based on the performance of the poller on a dual 733 MHz
and figured that I could Monitor ~200 hosts & ~4000 Interfaces with a
dual 2.0 GHz machine with 150 GB of Hard drive space. Do you think this
is accurate?
Thanks in advance,
Kory Knopp
