Are macros allowed to be used inside custom variables? I'm using Nagios
3.2.3. I was experimenting with using custom variables in host
definitions for clusters. I couldn't figure out if there was a way to
make this work.
It didn't seem to matter how I escaped the $s or not, whether I used
$_hostwarn$ or just $_warn$, or if I defined new commands with the
custom variables in place of $ARGn$.
I already have cluster checks which don't use custom variables and work
fine, and other service checks which use custom variables from the host
for parameters and also work fine.
One of my working cluster checks returns this:
CLUSTER OK: dmz_cluster_1: 3 ok, 0 warning, 0 unknown, 0 critical
However, I set up another check for the same cluster using custom
variables, and it returns this instead:
CLUSTER CRITICAL: dmz_cluster_1_foo: 1 ok, 0 warning, 0 unknown, 0 critical
Here's an example of what I was trying to accomplish:
define host {
use esx-server
name esx-cluster
host_groups esx_clusters
check_command check_cluster!host!@$_warn$:!@$_crit$:!$_hostcluster$
register 0
}
define host {
use esx-cluster
host_name esx_cluster_1
alias esx_cluster_1
parents parent1,parent2,parent3
_warn 1
_crit 2
_hostcluster
$HOSTSTATEID:parent1$,$HOSTSTATEID:parent2$,$HOSTSTATEID:parent3$
_servicecluster
$SERVICESTATEID:parent1:Ping$,$SERVICESTATEID:parent2:Ping$,$SERVICESTATEID:parent3:Ping$
}
define service {
use standard_service
host_name esx_cluster_1
service_description cluster_health
display_name cluster_health
check_command
check_cluster!service!@$_warn$:!@$_crit$:!$_servicecluster$
}
define command {
command_name check_cluster
command_line $USER1$/check_cluster --$ARG1$ --label=$HOSTNAME$
--warning=$ARG2$ --critical=$ARG3$ --data=$ARG4$
}
