Appreciate some help in this regard..<o:p></o:p> <o:p> </o:p> 1. Latency: The average Latency value is 70.24 Seconds for all the services but I believe is way too high. I browsed the site (<a href="http://nagios.sourceforge.net/docs/2_0/tuning.html">http://nagios.sourceforge.net/docs/2_0/tuning.html</a>) but couldn’t exactly figure out how to reduce this figure. How do I go about reducing the Latency figure ?<o:p></o:p> <o:p> </o:p> <o:p> </o:p> 2. Regarding Parallelize Check: (This directive is used to determine whether or not the service check can be parallelized. By default, all service checks are parallelized. Disabling parallel checks of services can result in serious performance problems.)<o:p></o:p> <o:p> </o:p> From what I can understand, Parallelize check means that if I have a Service check configured to run every 3 minutes, and Nagios determines that even though the previous check launched 3 mins ago has still not finished it launches a new check !? Am I correct in this assumption ? If yes, how can Disabling this result in performance problems ? shouldn’t it be viceversa ?<o:p></o:p> <o:p> </o:p> <o:p> </o:p> 3. Finally, In a service configuration file, I have the following:<o:p></o:p> Maximum Check Attempts: 5<o:p></o:p> Normal Check Interval In Time-Units: 5<o:p></o:p> Retry Check Interval In Time-Units: 3<o:p></o:p> <o:p> </o:p> In the above, Shouldn’t the Normal Check Interval be Greater than Maximum Check Attempts * Retry Check Interval ? <o:p></o:p> <o:p> </o:p> <o:p> </o:p> TIA,<o:p></o:p> <o:p> </o:p> sg<o:p></o:p> </div> </body> </html> <table><tr><td bgcolor=#ffffff>===================================================================== CAUTION: This e-mail and any attachment(s) contains information that is intended to be read only by the named recipient(s).
