installing nagvis

nagvis is a visualisation addon for nagios. i think the idea is that you can view a dynamically generated diagram of your environments. but you have to configure the drawing rules yourself, using an x/y coordinate system. this post is just about installing nagvis, not configuring it

extract the Nagvis source code tarball to /usr/local/

$ tar -zxvf nagvis-1.7.10.tar.gz -C /usr/local/

move the nagios share directory

edit the main configuration file. the configuration options are described at http://docs.nagvis.org/1.8/en_US/nagvis_config_format_description.html

$ cp /usr/local/nagvis-1.7.10/etc/nagvis.ini.php-sample /usr/local/nagvis-1.7.10/etc/nagvis.ini.php $ vim /usr/local/nagvis-1.7.10/etc/nagvis.ini.php configure the webserver: $ cp /usr/local/nagvis-1.7.10/etc/apache2-nagvis.conf-sample /etc/httpd/conf.d/apache2-nagvis.conf

replace all occurrences of

@NAGVIS_WEB@ with /nagvis @NAGVIS_PATH@ with /usr/local/nagvis-1.7.10/share

check which unix user is used to run your webserver

$ grep -e '^User' /etc/httpd/conf/*.conf

assuming the user is 'apache', set file and directory permissions as below

$ mkdir -p /usr/local/nagvis-1.7.10/var/tmpl/cache $ mkdir /usr/local/nagvis-1.7.10/var/tmpl/compile $ chown -R apache:root /usr/local/nagvis-1.7.10 $ chmod 664 /usr/local/nagvis-1.7.10/etc/nagvis.ini.php $ chmod 775 /usr/local/nagvis-1.7.10/etc/maps $ chmod 664 /usr/local/nagvis-1.7.10/etc/maps/* $ chmod 775 /usr/local/nagvis-1.7.10/etc/geomap $ chmod 664 /usr/local/nagvis-1.7.10/etc/geomap/* $ chmod 775 /usr/local/nagvis-1.7.10/share/userfiles/images/maps $ chmod 664 /usr/local/nagvis-1.7.10/share/userfiles/images/maps/* $ chmod 775 /usr/local/nagvis-1.7.10/var $ chmod 664 /usr/local/nagvis-1.7.10/var/* $ chmod 775 /usr/local/nagvis-1.7.10/var/tmpl $ chmod 775 /usr/local/nagvis-1.7.10/var/tmpl/cache $ chmod 664 /usr/local/nagvis-1.7.10/var/tmpl/cache/* $ chmod 775 /usr/local/nagvis-1.7.10/var/tmpl/compile $ chmod 664 /usr/local/nagvis-1.7.10/var/tmpl/compile/* $ cp -r /usr/local/nagvis-1.7.10/docs /usr/local/nagvis-1.7.10/share
