Icinga2 – failure at monitoring /dev/shm
I wanted to monitor /dev/shm but icinga couldn’t get the values.
“DISK UNKNOWN – free space:”
After a look in the debuglog i found out that the parameter “-X” was set to tmpfs.
Because shm is a tmpfs filesystem you must configure disk_exclude_type to “nothing”.
Object Host:
vars.disks[“shm”] = {
disk_partitions = [ “/dev/shm” ]
disk_wfree = “10%”
disk_cfree = “5%”
disk_exclude_type = “”
}
apply service:
apply Service for (disk => config in host.vars.disks) {
import “notification-enabled”
import “10minute-service”
check_command = “disk”
command_endpoint = host.name
display_name = “Speicherplatz”
vars += config
}
After a restart it is working:
