Hello fellow Opsview users.
My company has had Opsview in use for a little over a year now and I think we
are starting to see some growing pains as more stuff gets added.
We are currently using version 3.5.0 on Ubuntu 8.04 , reverse tunnel
master/slave setup.
MySQL is running on the master server.
We only have 466 hosts and 1557 services but those checks are distributed
across 19 slave servers.
The master server is running on a VMWare ESX 3.5 host.
ESX Server CPU hovers between 20-35 %
ESX Server RAM is around 80%
The master Opsview server currently has 2 GB RAM, although it appears mysql is
using about half of it.

- One core issue we see other than general slowness is some of cgi's
just time out. We have some people that still like the old statusmap.cgi but
the full map never renders and the CPU spikes at 100%.
- Also on the new Events View we always get script time out errors in
the browser and the load time of events is pretty slow.
- Also I see a fair number of timeout errors in the ospview log

I'm looking for ideas on what the core bottleneck might be? I could add more
memory to the server, I could move MySQL to a different server, maybe move some
files to a RAM disk?
I'm willing to make upgrades where needed I just want to make sure I use
resources wisely..
Thanks for any advice you all may have.
