Service state in notification command argument

Icinga 2

Hi,

I’m using the notification object with commands to send SNMP traps to another system. This is working fine while using custom vars in my service.
I need to use our vars as the receiving system is using other states than the standard icinga service states - e.g.:
Icinga service state = “0” => Target system state = 2
icinga “1” => Target 1
Icinga “2” => Target 4

As you can imagine now, a critical event in Icinga would trigger a clear on the other side.

My question is now: How can I change the service.state within a command’s argument using DSL?
Currently I used things like:

if (service.state == 2){
  return 4
} else if (service.state == 1){
  return 1
} else {
  return 2
}

Not working - always a “2” is sent out.

Than I tried

var servicestate = macro("$service.state$")
if (servicestate == 2) {  //or "CRITICAL"
  return 4
}
...

Not working - always an empty string.
Maybe it’s quite simply, but currently I’m stucked…

System info:

  • Version used: icinga2 - The Icinga 2 network monitoring daemon (version: r2.14.2-1)
  • OS: Debian 11
  • Enabled features: api checker icingadb mainlog notification
  • Icinga Web 2 version: 2.12.1

Many thanks in advance

Do you use the director?

Do you use a lamda?

Why not map the logic in the notification program? It’s probably easier.

Some, like the one for Teams, are DSL directly in the notification command without a separate script / program. But besides this caveat, a very valid approach.

Hi - I’m using the director - forgot the “small” info :wink:

this was just another test… therefore another code inside

Edit: sorry, need more coffee.

maybe some of this code helps

var output_status = ""
var total_count = 0
var ok_count = 0
var critical_count = 0
var service_host = macro("$host.name$")
var service_names = get_services(service_host).map(s => s.name)
var service_pattern = macro("$116_all_of_them_service_pattern$")

//output_status += service_host + " "
//output_status += service_pattern + " "

for (service_name in service_names) {
//output_status += service_name + " "
  if (match(service_pattern, service_name)) {
    if (get_service(service_host, service_name).state == 2 && get_service(service_host, service_name).state_type == 1) {
      critical_count += 1
    } else {
      ok_count += 1
    }
    total_count += 1
  }
}
...

Hello again,

so I finally got it running. May ideas were all ok so far - only the bash script being called had an issue :triumph:
So the final solution is looking like this:

var service_host = macro("$host.name$")
var service_name = "Reachability"
if ( get_service(service_host, service_name).state == 1){
    return 1
} else if (get_service(service_host, service_name).state == 2){
   return 4
} else {
    return 2
}

The only think which drove me crazy was sending a 0 (zero) as command argument value. It looks as Icinga is ommiting such value some how (or I didn’t find it in the doc).
By changing now
value type to Icinga DSL and
value to return 0
I could solve this also.

Many thanks to you all!
