Nagios and Cacti

[Andrew Davis]

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.
