Thanks Wim,

Hmm so this means I have to have the following columns for example:

ibmupstemp hpupstemp ibmpdutemp etc

or

I just have

Temperature Humidity in each message for each of the above..

Shame, would have liked to have kept just 'temp' column for all. Unless of course I change the name of all the oids so they are all the same even if the 1.3.6.1 etc are different. Actually I think the name in message is just parsed so that's all that is important.

Thanks again!

Steve

Hello Steve,

I would have perhaps asked in the Devmon mailing list but my question is quite pertinent to Xymon too and this mailing list is a little more active with many using Devmon.

I have a check, it's called temp.

I have a Devmon template for an IBM UPS device and I have a template for an IBM PDU device. Both have a temp check for reading temperature and humidity.

The IBM UPS template has existed for a while and has been displaying temp graphs. I have temp=ncv, temp in GRAPHS and an entry in graphs.cfg and xymonserver.cfg.

What happens when you introduce a temp check to a new device that has a different template? Do you have to create an extra line in graphs.cfg/Xymonserver.cfg? Is it the same name?

ie do I have to use

NCV_temp=temperature:GAUGE (temperature being what is parsed from message file of template) for template 1 (IBM UPS)

and

NCV_temp=pdutemperature:GAUGE (pdutemperature being what is parsed from message file of template) for template 2 (IBM PDU)

OR

Do I have to use a different check/column name for each use of temperature per device? I might use Devmon for temperature/Humidity readings on a UPS device, or a PDU, or a server, or a network device and the templates I use in Devmon will be completely different. In which case I would have to use temppdu for example in xymonserver.cfg/Graphs.cfg alongside the existing temp

As fas as I know, you can only associate one graph template with one test (column), the template having the same name as the test. It is thus not possible to associate one template out of a set with a given instance of a test (in other words with a given {test,host}-pair). However, you can minimise the number of columns (in for instance 'all non-green' while it is very hot) by having the various tests to deliver the same NCV-data.

I recognise your problem, wanting to show the temperature for various network switches, some having only one temperature sensor, and some having thirty sensors. This is solved by sending always 3 numbers, the minimum, the average and the maximum value of all sensor values. For this purpose I have extended Devmon with a new transformation, called STATISTIC. (See patch #20 at http://sourceforge.net/p/devmon/patches/?source=navbar).

HTH, Wim Nelis.
