format problems with self written data input mehode

[dom]

hi all,

i have problems with a self written methode. i wrote a perlscript who gives back 3 attributes in this format

Code: Select all

vara:1000 varb:2000 varc:3000

but then, the grpah has no entry, as well as the rrd-file doesn't get updatet..
when i change the format to:

Code: Select all

vara:1000
varb:2000
varc:3000

(linefeeds "\n")
then i have the second attribute correctly, the other two are empty as well.. :-(

has anybody have an idea what i'm doing wrong?
thanks
dom

First one is correct, but make sure you don't have a space at the end.

Also, remember that you need a linefeed at the end.

... and please print the output with one statement as cactid (if you're using this poller) does not wait for all prints to complete. So

Code: Select all

print "vara:$vara";
...
print "varb:$varb";
...
print "varc:$varc\n";

would not be ok. Use

Code: Select all

print "vara:$vara varb:$varb varc:$varc\n";

instead. Pay attention not to introduce a space between the variable name and the value itself.
