I wanted to disable a specific host (the services/checks).
My raspberry pi is currently without an sd-card and it should not be monitored anymore.
I found out that there is a check command „dummy“ which is saying that the service is fine, but i don’t want fake values which is saying that the system is up.
Also it is just saying that the host is ok and not all of the services/checks.
My solution:
First of all i have commented out the import commands. You should split your services into host groups. For example my category server-linux allocates specific services to all of my linux servers. If the server is apt-based there are some checks with aptitude (for other systems you can have groups for eg. pacman (packet manager)).
After that i have commented out my temperature and humidity sensors, so that these settings are not loaded.
I also found out that commenting out multiple lines doesn’t work 🙁
You can also go to icingaweb -> overview -> hosts -> HOSTNAME -> downtime -> schedule downtime (select all services)
root@monitoring:~# nano /etc/icinga2/zones.d/master/hosts/sensors.conf
object Host "sensors.mattionline.lan" {
import "generic-host"
//import "server-allgemein"
//import "server-linux"
//import "apt-based"
//import "server-home"
address = "192.168.2.121"
display_name = "sensors.mattionline.lan"
/* ds1820 sensors for temperature check */
// vars.temperature_sensor = [
// "28-0116106adaee",
// "28-01161078fbee"
// ]
// vars.dhtpin = [
// "7"
// ]
}
