Not all values are graphed.

[Cornmeister]

Hi all,

I made a little Perl script,
the output is quite simple, just 4 values:

Code: Select all

BitrateInstant:45926221 BitrateMin:34936386 BitrateMax:58646912 BitrateAvg:45079603

I made a data input method, with 4 output fields, exactly the same as the script output.

I also made a graph Template and a data source.
As shown in the attached graph example, only one item is graphed, instead of the four.

The cacti log doesn't show any errors, the script output seems ok.

my cacti version is 0.8.7b

cacti 0.8.7e is the latest.

Did you follow http://docs.cacti.net/manual:087:3a_adv ... ut_methods ?

In cacti.log with debugging mode, do you see all the script output being mapped to all the data input / template fields?

I followed the manual, and it looks like all mappings are ok:

Code: Select all

Alright, good. Next, is the rrd file getting updated with all of those values?

What's the easiest way to check it out ?

[BSOD2600]

Same way you saw the mapping -- cacti.log in debug mode. Track the DS[##] for your script -- the rrd file should have that DS ## in it too.

This is the part of the log I was able to find:

Alright that portion of the log looks ok too.

Please post the graph debugging output (should've had you do this first).
