Introduction

A utility called naemonstats is included in the Naemon distribution. It is compiled and installed along with the main Naemon daemon. The naemonstats utility allows you to obtain various information about a running Naemon process that can be very helpful in tuning performance. You can obtain information either in human-readable or MRTG-compatible format.

Usage Information

You can run the naemonstats utility with the –help option to get usage information.

Human-Readable Output

To obtain human-readable information on the performance of a running Naemon process, run the naemonstats utility with the -c command line argument to specify your main configuration file location like such:

[naemon@lanman ~]# /usr/local/naemon/bin/naemonstats -c /usr/local/naemon/etc/naemon.cfg

[naemon@lanman ~]#

As you can see, the utility displays a number of different metrics pertaining to the Naemon process. Metrics which have multiple values are (unless otherwise specified) min, max and average values for that particular metric.

MRTG Integration

You can use the naemonstats utility to display various Naemon metrics using MRTG (or other compatible program). To do so, run the naemonstats utility using the –mrtg and –data arguments. The –data argument is used to specify what statistics should be graphed. Possible values for the –data argument can be found by running the naemonstats utility with the –help option.

Note: Information on using the naemonstats utility to generate MRTG graphs for Naemon performance statistics can be found here.
