I am running nagios on a dual xeon 2Ghz, 2,5gig internal memory. I have currently 260 hosts and 1400 services added to nagios. The services are scheduled to be checked with a 5 minute interval. The word scheduled is not accidently chosen, since in practise, the server is only succeeding in checking the hosts and services every 15-30 minutes. There is a milelong queue with checks that are behind on schedule. The server itself (CPU and Memory), is not even sweating a little bit. There are more then enough resources to serve the requests... I just changed nagios.cfg a bit today and am now allowing for 100 concurrent checks, but still no luck :-( Is there anyone on the list that know some tricks on reducing the delay and improving performance? maarten 111 processes: 110 sleeping, 1 running, 0 zombie, 0 stopped CPU0 states: 0.0% user, 0.0% system, 0.0% nice, 100.0% idle CPU1 states: 0.0% user, 0.0% system, 0.0% nice, 100.0% idle CPU2 states: 2.1% user, 1.0% system, 1.0% nice, 95.0% idle CPU3 states: 0.0% user, 0.0% system, 0.1% nice, 99.0% idle Mem: 2581768K av, 124044K used, 2457724K free, 0K shrd, 17920K buff Swap: 1024088K av, 9400K used, 1014688K free 19288K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND nagios.cfg command_check_interval=-1 max_concurrent_checks=100 (should be enough for 30000 checks in 5 minutes) service_reaper_frequency=10 sleep_time=1 service_check_timeout=60 host_check_timeout=45 event_handler_timeout=30 notification_timeout=30 ocsp_timeout=5 perfdata_timeout=5 execute_service_checks=1 check_service_freshness=1 freshness_check_interval=60 ------------------------------------------------------- This SF.net email is sponsored by: ObjectStore.
