me, admin of an Icinga2 Server with around 750 Hosts and 10.5k Services noticed, that my service view is getting slower and slower from time to time (better: every view which includes services).
System is all up to date, including php, icinga2 itself and CentOS 7.
We migrated 31 (increasing) Satellites with seperated zones each. Satellites are connected over WAN.
Master is a VMware VM with 4 Cores and 8GB RAM, 100GB of SSD.
How can I stop the server, getting slower and slower? Are there any kind of system requirements or recommendations?
All cores chilling at 5-15%, but if I click the service view, they jump to 90-95% for 1-2 seconds and the page won’t show until then.
Additionally I’m getting performances peaks every 45 minutes and I don’t know why.
Is this behaviour getting better with the “icinga2 database” which is coming?
Do you have any tips to get the server clean and fast as possible?
