| + | '''The Nagios Grapher contrib is no longer supported.''' |
| − | {{Needs review}}
| |
| | | | |
| | + | The [[Nagios]] contrib now includes the PNP graphical perfomance data analyser. PNP integrates much better into Nagios 3 than Nagios Grapher. In contrast to Nagios Grpaher, PNP is under ongoing development and much better documented. |

| − | === Introduction ===
| |
| − | The [[Nagios Grapher]] is a Nagios addon that collects performance data and represents these as graphs. [http://www.nagioswiki.org/wiki/Addon:NagiosGrapher Read more...]
| |
| − | | |
| − | This contrib installs the Netways Nagios Grapher v1.6.1-rc5 and requires [[Nagios]] installed, configured properly and running.

| − | === Download ===
| |
| − | Download the RPM from http://mirror.contribs.org/smeserver/contribs/michaelw/sme7/nagiosgrapher
| |

| − | === Installation ===
| |
| − | | |
| − | ==== Configure the dag repositoy ====
| |
| − | {{Repository|dag}}
| |
| − | | |
| − | ==== Installation of the Nagios Grapher package ====
| |
| − | /usr/bin/yum --enablerepo=dag localinstall smeserver-nagiosgrapher-*-0.noarch.rpm

| − | To add a Nagios Grapher link into the Nagios Reporting Menu apply one of the following patches:
| |
| − | | |
| − | If you have the Nuvola theme installed, run:
| |
| − | patch -p0 /usr/share/nagios/side/dtree_data.js < /usr/share/nagios/nagiosgrapher/gui-patch/dtree_data.js-nagiosgrapher.patch
| |
| − | | |
| − | otherwise run:
| |
| − | patch -p0 /usr/share/nagios/side.html < /usr/share/nagios/nagiosgrapher/gui-patch/side.html-nagiosgrapher.patch
| |
| − | | |
| − | === Configuration ===
| |
| − | You need to edit serveral configuration files:
| |
| − |
| |
| − | in <tt>/etc/nagios/nagios.cfg</tt> add/modify
| |
| − | cfg_dir=/etc/nagios/serviceext
| |
| − | process_performance_data=1
| |
| − | service_perfdata_command=process-service-perfdata
| |
| − | | |
| − | in <tt>/etc/nagios/commands.cfg</tt> add/modify
| |
| − | define command {
| |
| − | command_name process-service-perfdata
| |
| − | command_line /usr/share/nagios/fifo_write.pl /var/log/nagios/rw/ngraph.pipe '$HOSTNAME$\t$SERVICEDESC$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n' 3
| |
| − | }
| |
| − | | |
| − | Create files in <tt>/etc/nagios/ngraph.d</tt> to configure the graphs. You may use the files in <tt>/etc/nagios/ngraph.d/samples/</tt> as a starting point. Also consult the documentations in <tt>/usr/share/nagios/nagiosgrapher/doc/CONFIG</tt> and the links listed in the [http://wiki.contribs.org/index.php?title=Nagios_Grapher&action=submit#References References] section below.
| |
| − | | |
| − | This contribs has the file <tt>/etc/nagios/ngraph.d/cpuload.ncfg</tt> included which generates a graph for service definitons where the service descriptions contains the word "load". This works 'out of the box'.
| |
| − | | |
| − | Finally restart the services:
| |
| − | service nagiosgrapher restart
| |
| − | service nagios restart
| |
| − | | |
| − | '''Known problem:''' After install the nagiosgrapher won't start.
| |
| − | | |
| − | Workaround: Start the script manually:
| |
| − | /usr/bin/perl -w /usr/share/nagios/collect2.pl
| |
| − | After the next reboot the service will start.
| |
| − | | |
| − | '''Known problem:''' The graphes doesn't show anything
| |
| − | | |
| − | Solution: Delete corresponding rrd directory
| |
| − | service nagiosgrapher stop
| |
| − | rm -rf /var/lib/nagios/rrd/<HOST>
| |
| − | service nagiosgrapher start
| |
| − | | |
| − | Make sure that all files and directories under <tt>/etc/nagios/</tt> are owned and writable by user 'nagios'.
