Dear Maintainer,
When I tried to graph apache2 stats with collectd/collection.cgi, I got these
results:
* No graph is generated for this plugin (others plugins are graphing ok).
* Apache have mod_status enabled and configured (I can access it via brwoser
and wget).
* Apache's log contains some lines like this:
collection.cgi: RRDs::graph: No DS called 'count' in
'/var/lib/collectd/rrd/jb1.example.org/apache-raiz/apache_bytes.rrd' at
/usr/lib/cgi-bin/collection.cgi line 787
After some googling, I found somewhere that the DS name in the rrd files
changed from 'count' to 'value'.
So I opened collection.cgi in vim and did ":960,1021s/count/value". This solved
the issue.
