Ah, ok, thanks for you fast answer.

ok, thats what i still have in my config files, ;o)
so i have to run the cricket-collector for example by cron right?

Alan: yes.  you can also run collect-subtrees to divide your config
into smaller chunks.  If you are just processing monitors, it
should be pretty quick....

what did you mean with global variable?
i just read about: monitor-thresholds = "<monitor-threshold> [, <monitor-threshold> ...]"
on http://cricket.sourceforge.net/support/doc/monitor-thresholds.html

Alan: In the cricket-conf.pl, you can disable the 2nd pass collector
run that processes thresholds via the skipMonitor variable.  It's
false by default I believe.

i wrote a perl script by my own with some parts from:
http://www.linux-magazine.com/issue/44/Perl_RDDtool.pdf
http://www.linux-magazin.de/Artikel/ausgabe/2004/06/perl/perl.html (german)

i used the RRDs.pm for that.
if you are interested in the code i think i have to do some
cleanup before ;o)

Alan: Interesting.  I introduced a new value for collect like this:

	collect = create

Then I patched collector:

 
    if (! -f $datafile) {
        return unless newRRD($name, $target);
    }

+    if (defined($target->{'collect'}) && $target->{'collect'} eq "create") {
+        Debug("Skipping target $tname due to collect=create tag."); 
+        return;
+    }

It just creates the data file if it doesn't exist. Works for me.
