Graphs for ipmitool
|
||||
-------------------
|
||||
|
||||
This is a set of shell-scripts to quickly create a webpage with pretty graphs!
|
||||
|
||||
Prerequisites are a webserver with cgi-bin support and RRDtool, a data
|
||||
collection and graphing utility you can get here:
|
||||
|
||||
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/
|
||||
|
||||
|
||||
First, decide on a directory where to store the RRDtool database files and make
|
||||
sure it exists. 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!
