Configure Service Alert Status

[asmgiadmin]

I've created a service check for NSClient++ and NRPE versions of remote hosts, to identify both the version of agent on host and to identify which hosts are properly configured. Currently, any host not properly configured is showing critical status for service check.

How can I keep a service from alerting as critical? I understand it's alerting as critical because check is failing, but in this case it is strictly information and does not require action.

You can just click on the service from the Nagios XI Home page->Service Details, and then click on "Disable notifications" under the "Quick Actions" menu.

I have notifications disabled, but since service check is failing, it's showing as critical and also listed as a problem.

In this case, service is not critical to any operation. Is it possible to prevent generating check failure as critical?

In this case, you may want to see if the "negate" plugin would do the job for you. It will revert critical to OK. See the usage below:

Code: Select all

/usr/local/nagios/libexec/negate -h
negate v1.4.16 (nagios-plugins 1.4.16)
Copyright (c) 2002-2008 Nagios Plugin Development Team

Negates the status of a plugin (returns OK for CRITICAL and vice-versa).
Additional switches can be used to control which state becomes what.


Usage:
negate [-t timeout] [-Towcu STATE] [-s] <definition of wrapped plugin>

Options:
 -h, --help
    Print detailed help screen
 -V, --version
    Print version information
 -t, --timeout=INTEGER
    Seconds before connection times out (default: 11)
    Keep timeout longer than the plugin timeout to retain CRITICAL status.
 -T, --timeout-result=STATUS
    Custom result on Negate timeouts; see below for STATUS definition

 -o, --ok=STATUS
 -w, --warning=STATUS
 -c, --critical=STATUS
 -u, --unknown=STATUS
    STATUS can be 'OK', 'WARNING', 'CRITICAL' or 'UNKNOWN' without single
    quotes. Numeric values are accepted. If nothing is specified, permutes
    OK and CRITICAL.
 -s, --substitute
    Substitute output text as well. Will only substitute text in CAPITALS

Examples:
 negate /usr/local/nagios/libexec/check_ping -H host
    Run check_ping and invert result. Must use full path to plugin
 negate -w OK -c UNKNOWN /usr/local/nagios/libexec/check_procs -a 'vi negate.c'
    This will return OK instead of WARNING and UNKNOWN instead of CRITICAL

Notes:
 This plugin is a wrapper to take the output of another plugin and invert it.
 The full path of the plugin must be provided.
 If the wrapped plugin returns OK, the wrapper will return CRITICAL.
 If the wrapped plugin returns CRITICAL, the wrapper will return OK.
 Otherwise, the output state of the wrapped plugin is unchanged.

 Using timeout-result, it is possible to override the timeout behaviour or a
 plugin by setting the negate timeout a bit lower.
