server exclude

[tonnag]

Hi,
i'm running "Nagios Core 4.4.6" and I thought I could exclude a hostname in the definition.

This works

Code: Select all

define service {
    use                     generic-service
    hostgroup_name          grp-raspbian
    service_description     ping
    check_command           check_ping!200.0,20%!600.0,60%
     check_interval          5
    retry_interval          1
}

But adding

Code: Select all

   host_name                !hass


in the block above result in an errors

Code: Select all

Error: Could not find any host matching '!hass'
Error: Failed to expand host list '!hass'

indeed there is no host named !hass but host_name hass is there. Did I miss something somewhere in excluding one host from the group in one service?

Thnx
Ton

I just found

Code: Select all

host_name                !*hass

and

Code: Select all

host_name                !?ass

eliminate the pre-check error, but still not excludes the server from the service check
placing the wildcard not directly after the exclamation mark but anywhere else, results in an error during pre-check

Well, ended up building a test machine from scratch. The "!" stops functioning when

Code: Select all

use_true_regexp_matching=1

reset to zero and off we go
