Nope, I need the tcp lines.

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" ?
