Command Argument will be handed over to a service even if the value isn´t set since icinga v2.12

Icinga Web Modules Icinga Director

Hi all,

maybe someone can give me a solution to this problem.
In my environment I´m doing the configuration with the icinga2 director module.

I´ve configured a command with different arguments since I´ve upgraded Icinga2 to v2.12.0 the command isn´t working anymore.

With inspect I can see some differences in the check call.

Old behavior:

‘//usr/lib/nagios/plugins/custom/check_http_curl’ ‘-C’ ‘’ ‘-c’ ‘45’ ‘-j’ ‘ARRAY’ ‘-u’ ‘MYURL’ ‘-w’ ‘30’

New behavior:

‘//usr/lib/nagios/plugins/custom/check_http_curl’ ‘-C’ ‘-c’ ‘45’ ‘-j’ ‘ARRAY’ ‘-u’ ‘MYURL’ ‘-w’ ‘30’

The value for the ‘-C’ Argument isn´t set for this Service but will be handed over without any value and so my check script fails. The old behavior was it will be handed over to the system call but with an empty value (’’), which was ok for my check script.

If I´m setting “skip key” to “yes” in the icinga2 director only the value will be parsed to the system call, so the script also fails if -C is required.

Thanks for your help!
Patrick

Both old and new behavior seem strange to me, tbh.
Can you show the command definition?

… and the host and service definitions?

Hi all,

this is the command definition from director preview tab:

object CheckCommand "linux-http-curl-status-custom" {
    import "plugin-check-command"
    import "command-template-linux"

    command = [ "/$PluginDirCustom$/check_http_curl" ]
    timeout = 118s
    arguments += {
        "-A" = "$HTTP_ACCOUNT_PASSWORD$"
        "-B" = "$HTTP_BROWSER_AGENT$"
        "-C" = {
            description = "Show details for command-line debugging"
            value = "$http_cipher$"
        }
        "-H" = "$http_header$"
        "-L" = {
            set_if = "$http_forward$"
            value = "yes"
        }
        "-N" = {
            set_if = "$http_noproxy$"
            value = "yes"
        }
        "-c" = {
            description = "Response time to result in critical status (seconds)"
            value = "$http_critical_time$"
        }
        "-d" = "$http_data$"
        "-h" = "$http_host$"
        "-j" = "$http_nocheck$"
        "-s" = {
            description = "String to expect in the content"
            value = "$http_string$"
        }
        "-u" = {
            description = "URL to GET or POST (default: /)"
            value = "$http_url$"
        }
        "-w" = {
            description = "Response time to result in warning status (seconds)"
            value = "$http_warn_time$"
        }
        "-x" = "$http_proxy$"
    }
    vars.check_address = {
        arguments = [  ]
        deprecated = false
        name = "<anonymous>"
        side_effect_free = false
        type = "Function"
    }
    vars.check_ipv4 = "$http_ipv4$"
    vars.check_ipv6 = "$http_ipv6$"
    vars.http_forward = true
    vars.http_invertregex = false
    vars.http_linespan = false
    vars.http_link = false
    vars.http_sni = false
    vars.http_verbose = false

For the -C Argument the Configuration looks like this:

The $http_cipher$ variable will be referenced in the host configuration but isnt set to any value in this case. But the -C parameter will be used in the command execution as shown before…

Thanks for your help!

Please share the host and service configs:

  • icinga2 object list -t host --name 'X'
  • icinga2 object list -t service --name 'X!Y'

Hi,

here is the configuration. I´ve deleted some variables because this is a productive server.

The “http_cipher” variable is referenced to the a custom Host variable “$host.vars.HTTPS_CIPHERS$” which is not set in this host configuration. So I´m wondering why the -C argument will be set in the command execution…

Thanks for your help!

Hi all,

It seems like the problem is caused because the $http_cipher$ variable will be filled by another referenced host variable. For some reason the argument will be applied even if the referenced variable is empty.

In my case this is a big problem. Is this a known behavior and are there any workarounds for this problem?

Thanks

Works for me:

➜  icinga2 git:(master) cat nestvar.conf
object CheckerComponent { }

object CheckCommand "lolcat" {
	command = [ "echo" ]
	arguments = {
		"a" = "$a$"
	}
}

object Host "lolcat" {
	check_command = "lolcat"
	vars.a = "$b$"
}

Hi,

my problem is the host variable which is referenced for this service is empty in the director host configuration but the argument will be used in the command execution so I think the problem is somehow icinga2 thinks there´s a value in the variable. Maybe this problem is because the argument variable will be filled with a referenced host variable. It seems like icinga2 is using the referenced host variable even if it´s empty.

Thanks for your help

Will be fixed in v2.12.1:
