Yes, definitely do that. I talk about how my team set up nagios and PNP to minimize delays in polling on my blog, though be warned that we break some of the rules that the documentation says to always follow, like doing a fork() in a NEB module and setting inter-check delay methods to n .. none. so while it works for us I know that a number of people on this list would probably balk at how we did things and call us idiots :). That in mind, so far we are very happy with the performance of our setup and we have not had any instability problems with it in the 5 months it has been in place and we are completing all of our checks within 5 minutes which for us is very important as all performance data is sent to a long-term data warehouse for graphing and analysis with other tools that interface with the long term data warehouse.

If you are seeing scheduled check times skew unacceptably over time or you are not completing all checks in the time you need to have them done, then yes, definitely dig deeper and work on tuning your installation and tuning how you send data from nagios to PNP. - Max ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
