number of datasources in RRD's created by NCV

Onderwerp: Re: [hobbit] number of datasources in RRD's created by NCV

You are probably missing a carriage return after the last value of the status message.

That's it! after adding a <cr> in the status message the third datasource is
also created in the rrd (I deleted the rrd and let hobbit create a new one).

thanks!

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.
