Performance tuning for passive checks
Posted: Tue Jul 17, 2018 11:52 am
Need assistance with performance tuning tips for apache. The setup is federated monitoring with XI as the central point of aggregation. For about 1200 passive hosts and passive 4500 services currently we observe about 25 requests per second on apache.
This is going to get increased to 3500 hosts and 15000 services results that will be submitted passively via ochp and ocsp commands.
I am about to have Ramdisk setup as described in the documentation, apart from are there any suggested tweaks for Apache to handle all those send_nrdp checks arriving via ochp and ocsp commands.
With the default settings it appears there will be contention. Before adding more hosts and services I would like to fine tune apache accordingly and get it prepared to accept those volumes maybe around 125 - 150 requests per second.
