Forward Nagios Event Log to Apsolab-Server

This article explain how to forward Nagios event log to Apsolab-Server. Nagios allows you to setup event handler for host and service events. To forward events to Apsolab-Server you need to:

Copy event scripts to Nagios location
Configure Nagios commands
Configure Nagios event handlers

Copy event scripts to Nagios location

Apsolab provides bash script to handle Nagios events (host and service). Those script files are located in /opt/apsolab/latest/script/nagios. Copy those files in Nagios event handlers directory /usr/local/nagios/libexec/eventhandlers. Change file owner and permissions (nagios:nagios 0750).

Configure Nagios commands

To configure Nagios commands you need to edit the commands.cfg file located in /usr/local/nagios/etc/objects. At the end of the commands file, add the following lines:

define command{
	command_name	apsolab_host_event
	command_line	/usr/local/nagios/libexec/eventhandlers/apsolab_host_event.sh  --host-name $HOSTNAME$ --host-address $HOSTADDRESS$ --state $HOSTSTATE$ --state-type $HOSTSTATETYPE$ --attempt $HOSTATTEMPT$ --text "$HOSTOUTPUT$ $LONGHOSTOUTPUT$ $HOSTPERFDATA$" --host 127.0.0.1 --ssl --port 5473
	}

define command{
	command_name	apsolab_service_event
	command_line	/usr/local/nagios/libexec/eventhandlers/apsolab_service_event.sh  --name $SERVICEDESC$ --host-name $HOSTNAME$ --host-address $HOSTADDRESS$ --state $SERVICESTATE$ --state-type $SERVICESTATETYPE$ --attempt $SERVICEATTEMPT$  --text "$SERVICEOUTPUT$ $LONGSERVICEOUTPUT$ $SERVICEPERFDATA$" --host 127.0.0.1 --ssl --port 5473
	}

This configuration assume that Apsolab-Server is located in localhost. If you install Apsolab product in a different host than use an appropriate value for --host parameter. If you don’t want to use SSL, remove --ssl parameter and set --port to 5472 or any other port you may have configure for TAG service.

WARNING: If Apsolab is in a different host than Nagios, copy /opt/apsolab/latest/bin/xlogagent.pl and /opt/apsolab/latest/bin/XLogAgent.pm to Nagios host and update apsolab_host_event.sh and apsolab_service_event.sh with the new file location. Update file owner and permissions (nagios:nagios 0750).

Configure Nagios event handlers

To configure Nagios event handlers you need to edit the nagios.cfg file located in /usr/local/nagios/etc. Add or replace the following parameters:

global_host_event_handler=apsolab_host_event
global_service_event_handler=apsolab_service_event

To make you change effective, restart Nagios service.

Note: You won’t see Nagios Service logger in Apsolab-Console until an event happen.
