[rrd-users] Graph Values.

[Steve Shipway]

(This is more of a PNP4Nagios question than an rrdtool question, but here
goes)

 

With PNP4Nagios, you can define custom templates for each check_command.  In
the share/templates directory, the templates are named xxx.php for a
check_command xxx.

 

These templates are PHP code that defines the RRDTool command line used to
generate the graph images.  So, you can make the graphs do anything RRDTool
can do¡­  since your existing graph looks different from the default, I¡¯m
guessing you already have a customised template.

 

To set the graph Y-axis lower bound, you can use --lower-limit to set the
min value (default is 0) and optionally --rigid to make this fixed even if
the graph value goes below the lower value (this will also affect the upper
limit option as well).

 

The code you¡¯ll need in there is something similar to:

 

$opt[1] .= ¡® ¨Clower-limit 10¡¯

 

But this will depend on how you¡¯re keying it, and if the values are in Gb
or in b

Folks,

 

I am graphing Disk Usage over time using PNP4Nagios.  Is there a way to
change the parameters of the graph so it shows a different minimum number
other than zero?  

Here is an example of one of the graphs:



 

Can this be changed so the range in the graph is not 0 ¨C 20, but 10 ¨C 20?


 

Also, how do you change the data source type?  If someone could help with
the syntax of the commands, that would be great. 

 

Thanks a lot!

 

Jon
