Command validation error with arguments


I’ve got a problem deploying a command with arguments using the Director.

The command I am trying to deploy looks like this:

object CheckCommand "printerbox_snmp" {
import "plugin-check-command"
command = PluginDir + "/check_snmp"
timeout = 30s
arguments += {
    "-H" = {
        description = "Host to connect to"
        order = 1
        value = "$snmp_host$"
    "-o" = {
        description = "OID to request"
        order = 2
        value = "$snmp_oid$"

When I’m deploying this configuration it tells me that the Validationcheck failed because:

Attribute ‘command’ must be an array if the ‘arguments’ attribute is set.

The whole message looks like this:

If I delete those arguments it deploys the command flawlessly.

So please help me, what’s wrong with tis definition?

  • Director version (System - About): 1.8.0

Hi & welcome to the icinga community,

you would need to replace

command = PluginDir + “/check_snmp”


command = [ PluginDir + “/check_snmp” ]

However, since snmp is already part of the ITL you don’t need to define it on your own.

Hi, Roland.

Thanks, that’s it.

I think about how it broke. I remember configuring this command normally in the director. When I look into the activity log of the director I can see that the command lack the square brackets from the beginning. In the director create command there are no square brackets around the command value.

I didn’t even manage to get them back into the configuration, using the director form. So I ended up into recreating the command from scratch and that contained those square brackets again.


I got it:

Accidentally I reproduced this behaviour: In the command definition I just set:
“Render as String:” to Yes.

Then those Brackets dissapear. If you set it back to “No” they are back again.

Is this an Director Issue?

I’m sorry, I don’t know as we don’t use the director for service definitions.
