Install NagiosGraph<\/strong><\/p>\n

First of all, this is running on Ubuntu 10.04.1 LTS x32. I installed Nagios 3.2.0 from the source packages (see another post on this site), and will be installing NagiosGraph 1.4.3. I’ve also installed Nagios-Plugins-1.4.15.<\/p>\n

This will probably be a lot of writing, but in the end it was definitely worth my time.<\/p>\n

Update System and Install SNMPD:<\/strong><\/p>\n

nano \/etc\/nagiosgraph\/nagiosgraph.conf<\/code>
\nSet the following:
\nperflog = \/var\/nagios\/perfdata.log
\nrrddir = \/var\/nagios\/rrd
\nmapfile = \/etc\/nagiosgraph\/map
\nnagiosgraphcgiurl = \/nagios\/cgi-bin
\njavascript = \/nagios\/nagiosgraph.js
\nstylesheet = \/nagios\/nagiosgraph.css
\nlogfile = \/var\/log\/nagiosgraph.log
\ncgilogfile = \/var\/log\/nagiosgraph-cgi.log<\/p><\/blockquote>\n

Set Permissions For RRD Directory, Log Files, CGI Files:<\/strong><\/p>\n

\nchown nagios \/var\/nagios\/rrd<\/code>
\nchmod 755 \/var\/nagios\/rrd<\/code>

\nchmod 664 \/var\/log\/nagiosgraph-cgi.log<\/code><\/p><\/blockquote>\n

Edit Nagios.cfg:<\/strong><\/p>\n

nano \/usr\/local\/nagios\/etc\/nagios.cfg<\/code>
\nprocess_performance_data=1
\nservice_perfdata_file=\/var\/nagios\/perfdata.log
\nservice_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$
\nservice_perfdata_file_mode=a
\nservice_perfdata_file_processing_interval=30
\nservice_perfdata_file_processing_command=process-service-perfdata<\/p><\/blockquote>\n

Edit Commands.cfg (make sure this is enabled\/correct):<\/strong><\/p>\n

nano \/usr\/local\/nagios\/etc\/objects\/commands.cfg<\/code>

\n command_name process-service-perfdata
\n command_line \/usr\/local\/nagios\/libexec\/insert.pl
\n}<\/p><\/blockquote>\n

Restart Nagios:<\/strong><\/p>\n

\/etc\/init.d\/nagios restart<\/code><\/p><\/blockquote>\n

Edit Apache Configuration:<\/strong><\/p>\n

This was already done for me from the Nagios install, but just verify it’s correct.
\nnano \/etc\/apache2\/conf.d\/nagios.conf<\/code>
\nScriptAlias \/nagios\/cgi-bin \/usr\/local\/nagios\/sbin
\n
\n# SSLRequireSSL
\n Options ExecCGI
\n AllowOverride None
\n Order allow,deny
\n Allow from all
\n# Order deny,allow
\n# Deny from all
\n# Allow from 127.0.0.1
\n AuthName “Nagios Access”
\n AuthType Basic
\n AuthUserFile \/usr\/local\/nagios\/etc\/htpasswd.users
\n Require valid-user
\n<\/Directory>
\nThere should be more below this, so just leave that alone.<\/p><\/blockquote>\n

Restart Apache:<\/strong><\/p>\n

apache2ctl restart<\/code><\/p><\/blockquote>\n

Test Your Site:<\/strong><\/p>\n

http:\/\/server\/nagios\/cgi-bin\/show.cgi<\/p><\/blockquote>\n

You shouldn’t get any errors. If you get a 500 internal error, the issue is with Apache. If you get a “no rrd data found” error, then the configuration of nagiosgraph is incorrect OR you haven’t waited long enough.<\/p>\n

You can try to run the script directly:<\/strong><\/p>\n

cd \/usr\/local\/nagios\/libexec<\/code>
\n.\/insert.pl<\/code><\/p><\/blockquote>\n

Then verify that there is some data in the RRD directory:<\/strong>
\nls \/var\/nagios\/rrd\/<\/code><\/p>\n

To get it to work with Windows Clients:<\/strong><\/p>\n

Edit the map file:
\nnano \/etc\/nagiosgraph\/map<\/code>
\nAdd the following to the END of the file:
\n# Service type: memory
\n# check command: check_nt -H Address -v MEMUSE -w 50 -c 90
\n#output: Memory usage: tootal:2467.75 Mb – used: 510.38 Mb (21%) – free: 1957.37 Mb (79%)

\n# Service type: ntdisk
\n# check command: check_nt -H Address -v USEDDISKSPACE -lc -w 75 -c 90

\n[ diskcrit, GAUGE, $3*1024**3 ],
\n[ diskmaxi, GAUGE, $5*1024**3 ] ];<\/p>\n

Save and close the file, then restart nagios (\/etc\/init.d\/nagios restart)<\/p><\/blockquote>\n

***EDIT***
\nUpdated – had “.conf” instead of “.cfg” under “edit nagios.cfg”
\nAdded chmod 777 for \/var\/nagios to allow perfdata.log to be written<\/p>\n","protected":false},"excerpt":{"rendered":"
