Hi all,

Has anyone had any luck setting up a graph for a devmon collected status? We are using devmon with a temperature monitor in our comms room but at the moment it show the exact message so:

Temperature Probe: Jacarta - interseptor

Average temperature: 21.65c

Temperature at probe 1: 22.80c Temperature at probe 2: 20.50c

(the message made via devmon) gets plotted as:

Temperature at probe 1: 22.80c : nan(cur) : nan(max) : nan(min) ..... Temperature at probe 2: 20.50c : nan(cur) : nan(max) : nan(min) .....

And instead of using any of the values simply makes more entries i.e. Temp at probe 1 increases to 22.90 it plots

Temperature at probe 1: 22.80c : nan(cur) : nan(max) : nan(min) ..... Temperature at probe 2: 20.50c : nan(cur) : nan(max) : nan(min) ..... Temperature at probe 1: 22.90c : nan(cur) : nan(max) : nan(min) .....

I have read the custom graph stuff from the help menu but that mainly seems aimed at scripts you make yourself and doesn't work when applied to this. Help :-)

Thanks, Jason.

The NCV backend should takes care of it :

/* If extra data after the value, skip to end of line */

What beats me is that the spaces should have been stripped off :

"Temperature at probe 1" should be "Temperatureatprobe1".

So I believe the problem is elsewhere.

Could you sent your NCV setup to the list ?

Jason, beware that DS names (once stripped) are limited to 19 characters, it may bite you in the future if you use such long names. (I'm finishing a patch that breaks this limit).

"22.80c" is not a number, is it?

Hi,

Oops ye sorry I put the information in wrong on the graph it shows "Temperature_at_probe_1:_22.80c" I have since changed the message to:

{statusColour} Probe 1(c): Temperature: 22.70 {statusColour} Probe 2(c): Temperature: 20.00

But now it just shows Probe : nan(cur) : nan(max) : nan(min)....

How do I send my NCV setup? The only thing I can think of is from hobbitserver.cfg:

TEST2RRD="......temperature=ncv"

NCV_temperature="Temperature:GAUGE,Temperature:GAUGE"

Try this :

the message could be formatted as :

temp probe 1: 22.7 temp probe 2: 20.00

your setup as : NCV_temperature="tempprobe1:GAUGE,tempprobe2:GAUGE,*:NONE" (add the *:NONE if you have nothing else to track)

It should give you a rrd with two DS.

Have you applied the following patch ? "The NCV custom graphs module would mistakenly include text from lines with no data into the name of the next dataset. Apply this patch. Note that any existing RRD files affected by this bug must be deleted, since this changes the names of the datasets inside the RRD files."

If not, you can get it at http://hswn.dk/hobbitsw/patches/ncv-ignoretext.patch or via the all-in-one patch (http://hswn.dk/hobbitsw/patches/allinone.patch).

See also http://hswn.dk/hobbitsw/patches/ for an howto apply a patch.

This is documented, and someone else posted a better answer. But don't let your BB experience lead you astray -- Henrik "fixed" a lot of things, including the BB dependence on disk files for record keeping. Now you need to explicitly "drop" a column for each host.

Use to you could just remove all the hist and histlogs

and the column would go away.

 

What's the way now? Where's it keeping the column info now?

 

I've removed the iostat, netstat, and vmstat hist, histlogs, and

rrd

files, and it still shows them on the columns (purple).

 

Thanks...James

One way is the NOCOLUMNS option (see hobbit man pages for full

details)

I've converted over from Big Brother to Hobbit.

 

How do I get rid of my vmstat, iostat, netstat on the columns?

 

I did have larrd running which put the columns on the main page.

 

Thanks...James
