Hi all, I faced problem with nagios service latency. My requirement is active service monitoring to router/ network device using "SNMP" and "Ping" command. My environment is big router with ~100 services per device. How can I optimized nagios config? Thank in advance. Note: I have information below ########## nagios -s ################ HOST SCHEDULING INFORMATION --------------------------- Total hosts: 173 Total scheduled hosts: 173 Host inter-check delay method: NONE Host inter-check delay: 0.00 sec Max host check spread: 2 min First scheduled check: Tue Oct 30 18:55:33 2007 Last scheduled check: Tue Oct 30 18:55:33 2007 SERVICE SCHEDULING INFORMATION ------------------------------- Total services: 1071 Total scheduled services: 1071 Service inter-check delay method: NONE Inter-check delay: 0.00 sec Interleave factor method: SMART Average services per host: 6.19 Service interleave factor: 7 Max service check spread: 3 min First scheduled check: Tue Oct 30 18:55:33 2007 Last scheduled check: Tue Oct 30 18:55:33 2007 CHECK PROCESSING INFORMATION ---------------------------- Service check reaper interval: 10 sec Max concurrent service checks: 2000 ####### nagiostats ############ Total Services: 1071 Services Checked: 1071 Services Scheduled: 1071 Active Service Checks: 1071 Passive Service Checks: 0 Total Service State Change: 0.000 / 28.360 / 0.321 % Active Service Latency: 0.131 / 162.251 / 63.118 sec Active Service Execution Time: 0.034 / 12.306 / 2.001 sec Active Service State Change: 0.000 / 28.360 / 0.321 % Active Services Last 1/5/15/60 min: 93 / 1071 / 1071 / 1071 Passive Service State Change: 0.000 / 0.000 / 0.000 % Passive Services Last 1/5/15/60 min: 0 / 0 / 0 / 0 Services Ok/Warn/Unk/Crit: 1011 / 0 / 2 / 58 Services Flapping: 2 Services In Downtime: 0 Total Hosts: 173 Hosts Checked: 173 Hosts Scheduled: 173 Active Host Checks: 173 Passive Host Checks: 0 Total Host State Change: 0.000 / 12.370 / 1.127 % Active Host Latency: 0.000 / 441.785 / 258.783 sec Active Host Execution Time: 2.519 / 2.632 / 2.534 sec Active Host State Change: 0.000 / 12.370 / 1.127 % Active Hosts Last 1/5/15/60 min: 17 / 67 / 173 / 173 Passive Host State Change: 0.000 / 0.000 / 0.000 % Passive Hosts Last 1/5/15/60 min: 0 / 0 / 0 / 0 Hosts Up/Down/Unreach: 172 / 1 / 0 Hosts Flapping: 0 Hosts In Downtime: 0 ####### My hardware ######## CPU: Xeon 2.8 x 2 RAM: 4 GB Disk: SCSI 36 GB 10000 RPM BR, Gillnaldo SC - __________________________________________________ Do You Yahoo!?
