Can the use of dependencies also be the cause of increased latencies? I too struggle with them and I'm running on lightly-loaded physical hardware. We have 2 servers doing the checks sending back to a central server. Both distributed nodes use ocsp/ochp, but they do nothing more than append results to a file (i.e. it exits quickly). Results are handled outside of Nagios.
What's odd is that distserver 1 and distserver 2 are configured the same distserver1: Hosts Checked 675 Services Checked: 4179 Active Service Latency: 0.000 / 3.155 / 0.382 sec Active Service Execution Time: 0.000 / 60.038 / 0.145 sec distserver2: Hosts Checked: 261 Services Checked: 4289 Active Service Latency: 0.000 / 169.977 / 81.300 sec Active Service Execution Time: 0.000 / 15.270 / 0.211 sec yet as you can see, distserver2's latency is much higher and always has been. I tried turning off EPN yesterday on distserver2 and it had no discernable effect. We added 400 new service checks yesterday on distserver2 (just more of the same checks we already do but on 26 new hosts) and the latency went from 35 to over 80. The checks we do are very different (Windows, Linux, Unix, many are app-centric) so it's difficult to compare exactly what runs on distserver1 and distserver2, but given the jump that was taken yesterday, I'm wondering if the fact that the type of checks on these new hosts are all built on dependencies make me wonder if that doesn't have something to do with it. These hosts (Windows) have a basic check for NRPE and all other checks on the host are dependent on the NRPE check succeeding. I have to move to all new Nagios servers very soon. I'm interested in Merlin, but given its non-production nature just yet, I'm hesitant to commit and I'm not sure if it will help me here.
