Hi @gvenka008c
This question might get better traction on the Monitoring Portal forums: https://monitoring-portal.org/index.php?board/117-icinga-2/
I think you need to add a new CheckCommand for check_cluster, then a new Service (apply), but I have not implemented the check myself

@jjethwa Thanks.

@gvenka008c np 😄

@jjethwa Tried this but couldn't have it work.
commands.conf
object CheckCommand "check_cluster" {
import "plugin-check-command"
command = [ "/usr/lib64/nagios/plugins/check_cluster" ]
arguments = {
"-l" = "$check_cluster_label$"
"-w" = "$check_cluster_warning$"
"-c" = "$check_cluster_critical$"
"-d" = "$check_cluster_data$"
}
}
#services.conf
object Service "my-cluster-check" {
host_name = NodeName
check_command = "check_cluster"
vars.check_cluster_label = "PING"
vars.check_cluster_warning = 1
vars.check_cluster_critical = 2
vars.check_cluster_data = {{ get_service("host1.net", "PING").state_id + ", " + get_service("host2.net", "PING").state_id }}
}
When I bring down one of the node, it is still showing OK status. Didn't see Warning. Will keep you posted with the findings :)

Hmm, seems like that's the correct config and parameters needed according to the check documentation: https://www.monitoring-plugins.org/doc/man/check_cluster.html
I wonder if there is a cluster health check setting that needs to be tweaked?
from icinga2.
@jjethwa Yes, still trying to figure it out on how to run it from command line. Not sure how to get his argument.
-d, --data=LIST
The status codes of the hosts or services in the cluster, separated by
commas
from icinga2.
I was trying to get the state of the host as shown below
vars.check_cluster_data = get_host("host1").state + ", " + get_host("host2").state
Both are returning value as 1
Check Cluster Data 1, 1
Any thoughts? Both the nodes are up and running. Is that the right way of getting the host state? Please suggest.

Hi @gvenka008c
Unfortunately I don't know enough about the clustering and cluster monitoring part of Icinga2. This might be helpful as it shows how to alert when a satellite server is down: https://monitoring-portal.org/index.php?thread/34549-solved-satellite-down-no-state-change/

thx @jjethwa
