Disk monitoring on remote hosts

Service Monitoring
1

Hello,

I have icinga2 installed on my monitoring server and I want to use it to monitor disk utilization on remote hosts. When I added disk checks, it checks the disk utilization of the monitoring server itself and not the utilization of the remote host, how can I add disk monitoring remotely?

Regards,

You need to set “command_endpoint” in your service check definitions to be the
machine you want the check to be run on.

Right now my hosts.conf and services.conf look like as follows: Could you please let me know how to add command_endpoint in my setup. I have a basic setup so far with just icinga2 installed on my monitoring server.

  • Hosts.conf-

/* Define disks and attributes for service apply rules in services.conf. /
vars.disks[“disk”] = {
/ No parameters. */
}
vars.disks[“disk /”] = {
disk_partitions = “/”
}
vars.disks[“disk /opt”] = {
disk_partitions = “/opt”
}

and services.conf look like this:

apply Service for (disk => config in host.vars.disks) {
import “generic-service”

check_command = “disk”

vars += config
}

You need to add the hostname to the service check so that it performs the
check on that host instead of on the Icinga server.

services.conf look like this:

apply Service for (disk => config in host.vars.disks) {
import “generic-service”

check_command = “disk”

Add here:

command_endpoint = host.name

vars += config
}

See Distributed Monitoring - Icinga 2
and specifically the section #pin-checks-in-a-zone for more details.

ok, right now I just have a basic setup with icinga2 installed, would remote monitoring need an agent setup? Where can I find the exact procedure for the agent setup?

Thanks

Er, yes - otherwise there is nothing to run the service check on the remote
machine.

Where can I find the exact procedure for the agent setup?

Alternatively, set up SNMP on the hosts you want to monitor, and use appropriate plugins (e.g. “check_snmp_storage”) doing queries from your central Icinga server. Then you don’t need any checks running on the hosts, and only one end-point (the std. one of the Icinga server itself).
