And just an FYI from my own experience... putting Nagios & Cacti on
the same server has been somewhat problematic for us. We have over 400
network devices between switches, routers, WAPs, etc. We also have
about 300 monitored servers. Initially I had Nagios and Cacti both on
one server with Cacti running via cron every 5 minutes. About every 5
minutes, my shells would become unresponsive for roughly 30 to 90
seconds. Turning off either Nagios or Cacti resolved the issue. Running
both seems to have hammered the server a bit (4Gb of RAM, 2 x dual core
2.x Ghz CPUs). We don't integrate Cacti and Nagios, however. Nagios
does both trending and alerts of all servers. Cacti does trending only
of all network devices/ports. Once I moved Cacti to its own server, all
was fine as far as load/latency went.<br>

There are a couple of examples in the nagios exchange page of different
approachs for integrating nagios and cacti. You should check that out. <br>
<br>
I believe the synchronization is going to cost you time and money, a
better approach is to use nagios + pnp4naigos (this generates nice
graphs) + check_snmp_int.pl (this for bandwidth tests). That way you
have only one place to place your configuration. There are tons of
other snmp plugins you can use for other tests (CPU, Memory, etc),<br>

all,<br>
<br>
I've been looking into making use of Cacti to act as an SNMP<br>
management tool which runs alongside my Nagios instance.<br>
<br>
Ideally, what I would like to do is have Cacti monitor various<br>
SNMP-exposed metrics on my hosts, and then have a service check in<br>
Nagios which parses Cacti's results (which I believe are RRD files)<br>
and send alerts etc.<br>
<br>
Nagios itself will still be used for running directly checks for<br>
services running, errors in log files etc.<br>
<br>
Does this approach make sense?<br>
<br>
One issue that I can think of is the difficulty in keeping the config<br>
files of Nagios and Cacti synchronised. I was planning on using Lilac<br>
Platform to act as my Nagios config file management tool, but how that<br>
is kept in synch with Cacti is a problem. Has anyone ever set up an<br>
arrangement like this before?<br>
<br>
Cheers,<br>
Chris<br>
