Hi,
My two cents....
Most of my graphs are very simple but I still run into occasional troubles that need to be sorted out. Maybe this will help, maybe not....
On your example; unless the ^tcp lines are needed then I would send only the Name Colon Value of 'sessions : 17'. Also, after making script changes and in-between the stop - start I would remove any old psessions.RRD files. Then check to see if the new rrd files are still giving you Not A Number. I assume you already have a stanza in hobbitgraph.cfg to display.
Regards,
Tim

Hi, I have a simple script that counts the number of connects we have for a certain port. Specifically, the ssh proxy port for HP NA.
My output looks like this:
Concurrent SSH Sessions
Sessions : 17

I see that I have issues as there are a bunch of colons. I want to graph just the number of sessions for each interval.
So I add "sshConns=ncv" to TEST2RRD And add the line
NCV_sshConns="Sessions:GAUGE"
To the end of hobbitserver.cfg. Oh, Xymon 4.2.3 currently. I have a test server on 4.3.0rc1, but it's not getting this data.
Then I killed hobbitd_rrd (both).
The rrd file is created but it's not good:

How to I get Xymon to just look at the one line "Sessions : 18" ?
