I have two central machines (one for backup) and 10 distributed servers to colect status and send them to the central servers. It´s working but I´m having serious performance problems. First the Tactical Overview on the central machines is taking almost 1 minute to refresh. I think that its because the status.dat file is too big (almost 100 MB). Second, the adddon PNP 0.4.14 is taking a long time to process the performance data files. These files are increasing faster than the capaciy of process_perfdata.pl <a href="http://process_perfdata.pl"><http://process_perfdata.pl></a> script to process them. I´ve already implement all the recommendation to improve Nagios performance. Besides, I´ve already changed the npcd.cfg and process_perfdata.cfg parameters to improve the npcd and process_perfdata.pl <a href="http://process_perfdata.pl"><http://process_perfdata.pl></a> performance. I tried to set "npcd_max_threads" in the npcd.cfg to 10, but than I started to lose data, because process_perfdata.pl <a href="http://process_perfdata.pl"><http://process_perfdata.pl></a> finished itself by timeout, that I change to 300 seconds. Can anyone help me to improve the performance of Nagios and PNP to this enviroment? P.S.: All my Nagios servers are virtual machines with Red Hat. The central servers have 2 CPUs and 2 GB of memory. The colectors have 1 CPU and 1 GB of RAM. Do you think that change the central servers to physical machine I will have a big performance improvement? How much? I think that this is a good test for Nagios. I have a demand to put 100.000 hosts with 200.000 services in this enviroment!!!!. Is it possible? Has someone a Nagios configuration so big?
