Hi Mark, I have set up MRTG to track nagios performace and it is reporting that latency for host and service checks are next to nothing and service execution time is just under 400 ms, however, host checks are coming back at around 4 seconds. Based on the samples that are in the MRTG section of the tuning guide, my stats would indicate that service execution times are fine, but that host execution checks are high. nagiostat says this, and if I am reading it right, it contradicts what MRTG is report: Nagios Stats 3.2.1 Copyright (c) 2003-2008 Ethan Galstad (www.nagios.org) Last Modified: 03-09-2010 License: GPL CURRENT STATUS DATA ------------------------------------------------------ Status File: /usr/local/nagios/var/status.dat Status File Age: 0d 0h 0m 21s Status File Version: 3.2.1 Program Running Time: 0d 5h 40m 15s Nagios PID: 5828 Used/High/Total Command Buffers: 0 / 0 / 4096 Total Services: 4987 Services Checked: 4987 Services Scheduled: 4970 Services Actively Checked: 4987 Services Passively Checked: 0 Total Service State Change: 0.000 / 5.860 / 0.001 % Active Service Latency: 0.236 / 477.406 / 458.101 sec Active Service Execution Time: 0.013 / 12.393 / 0.377 sec Active Service State Change: 0.000 / 5.860 / 0.001 % Active Services Last 1/5/15/60 min: 195 / 1799 / 4970 / 4970 Passive Service Latency: 0.000 / 0.000 / 0.000 sec 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: 4971 / 10 / 1 / 5 Services Flapping: 0 Services In Downtime: 0 Total Hosts: 241 Hosts Checked: 241 Hosts Scheduled: 241 Hosts Actively Checked: 241 Host Passively Checked: 0 Total Host State Change: 0.000 / 0.000 / 0.000 % Active Host Latency: 444.598 / 469.511 / 455.625 sec Active Host Execution Time: 0.152 / 4.045 / 3.779 sec Active Host State Change: 0.000 / 0.000 / 0.000 % Active Hosts Last 1/5/15/60 min: 8 / 19 / 241 / 241 Passive Host Latency: 0.000 / 0.000 / 0.000 sec 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: 241 / 0 / 0 Hosts Flapping: 0 Hosts In Downtime: 0 Active Host Checks Last 1/5/15 min: 8 / 38 / 267 Scheduled: 8 / 33 / 249 On-demand: 0 / 5 / 18 Parallel: 8 / 33 / 249 Serial: 0 / 0 / 0 Cached: 0 / 5 / 18 Passive Host Checks Last 1/5/15 min: 0 / 0 / 0 Active Service Checks Last 1/5/15 min: 332 / 1949 / 5883 Scheduled: 332 / 1949 / 5883 On-demand: 0 / 0 / 0 Cached: 0 / 0 / 0 Passive Service Checks Last 1/5/15 min: 0 / 0 / 0 External Commands Last 1/5/15 min: 0 / 0 / 0 ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
