Nagios nagiosgraph configuration method in Linux system

Principle:

By using the service_perfdata_file_processing_command instruction, each service data that is monitored by Nagios is passed to the/usr/local/nagiosgraph/bin/ insert.pl script processing, production RRD files.

Here's the Nagiosgraph configuration:

1. Get component

The code is as follows	Copy Code
# wget http://downloads.sourceforge.net/project/nagiosgraph/nagiosgraph/1.4.4/nagiosgraph-1.4.4.tar.gz # TAR-XZF Nagiosgraph-1.4.4.tar.gz # CD nagiosgraph-1.4.4

2. Testing environmental Requirements

The code is as follows

Copy Code

#./install.pl--check-prereq Checking Required PERL Modules Carp ... 1.04 Cgi... 3.15 Data::D umper ... 2.121_08 File::basename ... 2.74 File::find ... 1.10 Mime::base64 ... 3.07 Posix... 1.09 Rrds ... 1.2027 Time::hires ... 1.9717 Checking optional PERL modules Gd... 2.35 Checking Nagios Installation Found Nagios At/usr/local/nagios/bin/nagios Checking Web Server Installation Found Apache AT/USR/SBIN/HTTPD

What Perl modules are missing, install those modules, and pay attention to the version requirements.

3. Installation

The code is as follows	Copy Code
./install.pl--install

Press the ENTER key all the way.

4. Edit Nagios.cfg File

Under Nagios.conf file, add the following

The code is as follows

Copy Code

# process Nagios performance data using Nagiosgraph Process_performance_data=1 Service_perfdata_file=/tmp/perfdata.log service_perfdata_file_template= $LASTSERVICECHECK $| | $HOSTNAME $| | $SERVICEDESC $| | $SERVICEOUTPUT $| | $SERVICEPERFDATA $ Service_perfdata_file_mode=a Service_perfdata_file_processing_interval=30 Service_perfdata_file_processing_command=process-service-perfdata-for-nagiosgraph

5. Edit Commands.cfg File

Add the following content

The code is as follows	Copy Code
######################################### # # Nagiosgraph # # command to process Nagios performance data for Nagiosgraph Define Command { Command_name Process-service-perfdata-for-nagiosgraph command_line/usr/local/nagiosgraph/bin/insert.pl }

6. Modify the httpd.conf file

Add the following content

The code is as follows	Copy Code
Include/usr/local/nagiosgraph/etc/nagiosgraph-apache.conf

7. Restart Service

The code is as follows	Copy Code
#/etc/init.d/httpd Restart #/etc/init.d/nagios Restart

8. View Nagiosgraph configuration information

In the browser input: http://10.0.100.125/nagiosgraph/cgi-bin/showconfig.cgi URL view.

9. Define Action URL

Modify the Templates.cfg file and add the following:

define service {

name nagiosgraph

action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$

register 0

}

10. Add the drawing you need

By default, services that enable performance data will be plotted.

Examples are as follows:

define service {

use                 MongoDB,nagiosgraph

hostgroup_name          MongoDB_Servers

service_description     Mongo Memory Usage

check_command           check_mongodb!12345!''!''!memory!130!260

servicegroups           Mongodbservices

}

After adding, there will be an icon below

11. The effect is as follows

12. Each service item will have a RRD file

Under the/USR/LOCAL/NAGIOSGRAPH/VAR/RRD directory of each Autonomous machine directory

For performance data cannot be generated, the drawing cannot be drawn, nagiosgraph no data available information appears, and the following information is viewed Nagiosgraph.log:

322207-tue APR 8 17:18:36 2014 insert.pl warn Output/perfdata not recognized:
322279:hostname:x.x.x.x
322299-servicedesc:mongo Free Connections
322334-output:ok–6 percent (819 connections) used
322385-perfdata:

PerfData is empty, this needs us to analyze output information. By/usr/local/nagiosgraph/etc/map This file, you define a regular expression to handle, which is a Perl script that maps output information to PerfData.

Map How to customize regular expressions the next section, please pay attention.
