number of datasources in RRD's created by NCV

[Dennis Ortsen]

Hi all,

I've added a custom test to a host that sends (performance)
information about the mysql daemon that's running on it.

The data on the status page of that mysql test looks like this:

threads : 53
queries per sec : 386
slow queries : 0

All values are absolute (GAUGE) so I added this NCV tag in hobbitserver.cfg:

NCV_mysql="threads:GAUGE,queriespersec:GAUGE,slowqueries:GAUGE"

I also added "mysql=ncv" to the TEST2RRD list in hobbitserver.cfg I
kicked the hobbit daemons so the hobbitserver.cfg file would be read
again. The RRD file is created on the hobbit server after the client
has sent its data. When I check with `rrdtool dump mysql.rrd` I only
see the first two datasources (threads and queriespersec). The
third/last datasource isn't created/updated in the RRD file, although
you'd expect that according to the NCV_mysql tag in hobbitserver.cfg.

Is there a limitation in the maximum number of datasources the NCV
graphing can handle?

I'm running hobbit 4.2.0 on both client and server BTW.

Thanks in advance,

Br.
