6.5 Customizing Nagios Metrics Gathering
The nagios_template.cfg file specifies which metrics are gathered and how often. A
single Nagios service definition calls for sensor data and other metrics to be gathered with
thesamefrequency.
The following procedure enables you to edit the file and to apply two servi ce definitions: one
for the sensor data and the other for all other metrics.
1. Log in as the sup eruser (root) on the h ead node.
2. Use the text editor of your choice to edit th e /opt/hptc/nagios/etc/tem-
plates/nagios_template.cfg file as follows:
a. Locate the gatherMetrics service definition, as shown here:
define service{
use nagios
host_name %HOST%
name gatherMetrics
service_description Gather supermond metrics
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval 2
