Hi folks, I'm having some performance issues with a rather big Nagios 2.4 deployment (430 servers, 3000 service checks) .
I'm having now a 600-900 secs avg latency for checks - checks distribution is more or less like this : 450 check_icmp (scheduled every minute) 500 check_ifoperstatus (scheduled very 5 minutes) 800 check_nt (scheduled every 5-10 minutes) 200 check_http (scheduled every 5 minutes) 1000 check_by_ssh (scheduled every 5-10 minutes) 1730 Performance graphs generated by PNP I've already applied some performance tips specified in the nagios faq (aggregated status updates, max_concurrent_checks=0, checked hardware config, etc) Since load average for this server is always below 1, is there any way to force more concurrent checks per second? (btw, I've replicated the same config in a similar server with a Nagios 2.9 setup and ended with similar results as well) Thanks in advance :-) --- Output of nagiostat: Active Service Latency: 590.886 / 671.695 / 635.054 % Active Service Execution Time: 0.124 / 19.130 / 0.483 sec Active Service State Change: 0.000 / 49.930 / 0.238 % Active Services Last 1/5/15/60 min: 61 / 673 / 2150 / 2929 Output of nagios -s nagios.cfg : HOST SCHEDULING INFORMATION --------------------------- Total hosts: 424 Total scheduled hosts: 0 Host inter-check delay method: SMART Average host check interval: 0.00 sec Host inter-check delay: 0.00 sec Max host check spread: 30 min First scheduled check: N/A Last scheduled check: N/A SERVICE SCHEDULING INFORMATION ------------------------------- Total services: 2929 Total scheduled services: 2929 Service inter-check delay method: SMART Average service check interval: 433.36 sec Inter-check delay: 0.15 sec Interleave factor method: SMART Average services per host: 6.91 Service interleave factor: 7 Max service check spread: 30 min First scheduled check: Thu Sep 6 11:18:31 2007 Last scheduled check: Thu Sep 6 11:25:45 2007 -- Windows macht frei! ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
