The user that will run the cronjob to collect updates must have +write permissions in this dir. + +Next, you'll need to edit some variables at the top of each script. + +Common to all scripts: + +hostname Override this if you are collecting data from a remote host, + or if the $HOSTNAME variable is incorrect. + +ipmi_cmd Command line used to call ipmitool. Default is to collect + data from the local server using OpenIPMI. + + If you want to collect data from a remote host, add the + -I lan, -H, -U and -P options as necessary. + + BIG NOTE! I do not recommend using remote data collection since + you'll have to store the password in the script. If you do, + make sure unauthorized people can't read or execute the scripts + or they'll be able to wreak havoc on your server. + +rrd_dir Enter the dir where to store the RRDtool database here. + + +Now you can get the data collection going. Run create_rrds.sh to create the +RDDtool database, you'll find one .rrd file per sensor in the designated dir. +Add a line to your crontab that executes collect_data.sh every 5 minutes. + +Something like this: +*/5 * * * * /usr/local/bin/collect_data.sh + +If you are a Solaris user you'll have to write the more verbose: +0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/bin/collect_data.sh + + +Finally it's time to create the webpage, begin with editing some more variables +in the create_webpage.sh and/or create_webpage_compact.sh scripts: + +rrdcgi Full path to the rrdcgi executable. + +img_dir Directory to store the graph images. This path must be within + the document root and writable by the web server user. + + Example: /usr/local/apache2/htdocs/images/graphs + +web_dir Relative path of the URL where the images will show up + on the web server. + + Example: With the img_dir path above the corresponding web_dir + would be /images/graphs + +graph_width Size of the graph area in pixels (excluding title, legends etc.) +graph_height + +graph_daily Decide which of daily, weekly and monthly graphs you want +graph_weekly included on the page. +graph_monthly + + +Finally run the create webpage script and store the output as a cgi-script and +don't forget to make it executable. + +Example: + +create_webpage.sh > /usr/local/apache2/cgi-bin/my_ipmi_graphs.cgi +chmod 755 /usr/local/apache2/cgi-bin/my_ipmi_graphs.cgi + +Now you can surf to http://my.server.com/cgi-bin/my_ipmi_graphs.cgi and enjoy! + + +The difference between create_webpage.sh and create_webpage_compact.sh is that +the first script displays sensor thresholds in the graphs. The second script +collects all sensors that measure the same unit into the same graph thus +producing a lot fewer graphs. + +Note, RRDtool sometimes scales the graphs such that the sensor thresholds +fall outside the visible area. + + +Happy graphing! + + -- cgit v1.2.3
