Recipe for Manual Installation
------------------------------

These instructions assume an overlay layout, with nagios at /usr/local/nagios.

 - Extract nagiosgraph into a temporary location:
     cd /tmp
     tar xzvf nagiosgraph-x.y.z.tgz

 - Copy the contents of etc into your preferred configuration location:
     mkdir /etc/nagiosgraph
     cp etc/* /etc/nagiosgraph

 - Edit the perl scripts in the cgi and lib directories, modifying the
   "use lib" line to point to the directory from the previous step.
     vi cgi/*.cgi lib/insert.pl

 - Copy insert.pl to a location from which it can be executed:
     cp lib/insert.pl /usr/local/nagios/libexec

 - Copy CGI scripts to a script directory served by the web server:
     cp cgi/*.cgi /usr/local/nagios/sbin

 - Copy CSS and JavaScript files to a directory served by the web server:
     cp share/nagiosgraph.css /usr/local/nagios/share
     cp share/nagiosgraph.js /usr/local/nagios/share

 - Edit /etc/nagiosgraph/nagiosgraph.conf.  Set at least the following:
     perflog           = /var/nagios/perfdata.log
     rrddir            = /var/nagios/rrd
     mapfile           = /etc/nagiosgraph/map
     nagiosgraphcgiurl = /nagios/cgi-bin
     javascript        = /nagios/nagiosgraph.js
     stylesheet        = /nagios/nagiosgraph.css
     logfile           = /var/log/nagiosgraph.log
     cgilogfile        = /var/log/nagiosgraph-cgi.log

 - Set permissions of "rrddir" (as defined in nagiosgraph.conf) so that
   the *nagios* user can write to it and the *www* user can read it:
     mkdir /var/nagios/rrd
     chown nagios /var/nagios/rrd
     chmod 755 /var/nagios/rrd

 - Set permissions of "logfile" so that the *nagios* user can write to it:
     touch /var/log/nagiosgraph.log
     chown nagios /var/log/nagiosgraph.log
     chmod 664 /var/log/nagiosgraph.log

 - Set permissions of "cgilogfile" so that the *www* user can write to it:
     touch /var/log/nagiosgraph-cgi.log
     chown www /var/log/nagiosgraph-cgi.log
     chmod 664 /var/log/nagiosgraph-cgi.log

 - In the Nagios configuration file (/etc/nagios/nagios.cfg) add this:

     process_performance_data=1
     service_perfdata_file=/var/nagios/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

 - In the Nagios commands file (/etc/nagios/commands.cfg) add this:

     define command {
       command_name  process-service-perfdata
       command_line  /usr/local/nagios/libexec/insert.pl
     }

 - Restart nagios

     /etc/init.d/nagios restart

 - Verify that nagiosgraph is working by running showconfig.cgi

     http://server/nagios/cgi-bin/showconfig.cgi

 - Try graphing some data by running show.cgi

     http://server/nagios/cgi-bin/show.cgi

 - In the Nagios configuration, add a template for graphed services:

     define service {
       name graphed-service
       action_url /nagiosgraph/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$' onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()' rel='/nagiosgraph/cgi-bin/showgraph.cgi?host=$HOSTNAME$&service=$SERVICEDESC$&period=week&rrdopts=-w+450+-j
     }

 - Enable graph links for services by appending the graphed-service to existing
   service definitions in the Nagios configuration:

     define service {
       use local-service,graphed-service
       ...
     }

 - Replace the Nagios action icon with the nagiosgraph graph icon:
     cp share/graph.gif /usr/local/nagios/share/images/action.gif

 - In the nagiosgraph SSI file, set the URL for nagiosgraph.js:
     vi share/nagiosgraph.ssi
     src="/nagiosgraph/nagiosgraph.js"   ->    src="/nagios/nagiosgraph.js"

 - Install the nagiosgraph SSI file:
     cp share/nagiosgraph.ssi /usr/local/nagios/share/ssi/common-header.ssi

 - Modify the Nagios sidebar (e.g. /usr/local/nagios/share/side.php)
   by inserting bullets under the 'Trends' heading:

<li><a href="<?php echo $cfg["cgi_base_url"];?>/trends.cgi" target="<?php echo $link_target;?>">Trends</a>
<ul>
<li><a href="<?php echo $cfg["cgi_base_url"];?>/show.cgi" target="<?php echo $link_target;?>">Graphs</a></li>
<li><a href="<?php echo $cfg["cgi_base_url"];?>/showhost.cgi" target="<?php echo $link_target;?>">Graphs by Host</a></li>
<li><a href="<?php echo $cfg["cgi_base_url"];?>/showservice.cgi" target="<?php echo $link_target;?>">Graphs by Service</a></li>
<li><a href="<?php echo $cfg["cgi_base_url"];?>/showgroup.cgi" target="<?php echo $link_target;?>">Graphs by Group</a></li>
</ul>
</li>

 - Restart nagios

     /etc/init.d/nagios restart
