[rrd-users] Re: please help a lost newbie

[Simon Mullis]

Hi there....

If I were you I would use MRTG to perform the data collection for you.

You can specify a script or command in back ticks as the MRTG Target for it
to perform your script.  As long as your script returns data in the
following format all will be fine.

Format from script should be:

Variable
Variable

And in your mrtg.cfg:

...
Target[machine_X_users]:`/full/path/to/script/scriptname <machine_name>`
...

I'm sure some of the RRDTool purists here would baulk at this idea and
suggest you should call RRDTool directly, but if you already use MRTG for
other things and have the presentation mechanisms then this will work fine.

Thanks

SM

Subject: [rrd-users] please help a lost newbie



Ok I wrote a shell script to collect data from our boxes, simply a decimal
number. All the script does is: finger @host | grep -c tty > host1.users

shows the # of users logged into the box
I do this for about 20 boxes, each to a different file

I've tried reading the docs, faq, etc on the website, but
I just get lost, nothing seems to cover what I want to do.

How do I get this graphing the data ?
basically every 5 minutes I need something to build the
graph to show the users on the boxes graphed over time

Dan.
