[mrtg] Re: problems with disk/cpu data collections

[Daniel Curry]

Here is the output I get when I 'manually' run the script.  It has
nothing about uptime in the script and I am not sure what the <in data>
string should be.  this script came from the contrib directory.

[dcurry at neon run]$ perl ./getdisk.pl viper 14
15
[dcurry at neon run]$ 


If I use the ` instead of ' I get this message mailed to root:

Can't open perl script "./getdisk.pl": No such file or directory
Could not get any data from external command 'perl ./getdisk.pl viper 1'
Maybe the external command did not even start. (Illegal seek)

Still working with it here, but any suggestions would be helpful.

First off does this script produce data in the following format?

<in data>
<out data>
<uptime (any string)>
<target name>

So, if the disk was half full the output of your script should look
something like this:

50
0
a long time
Server1 disk 1

Make sure you are using the backtick (` under the tilde (~) on a US
keyboard), not the single quote ('), in the Target line.

Use gauge.  You don't need a difference calculated, and you don't need
the
number divided by the polling interval. 

HTH,
