Hello,

I read all messages, but i have a problem with the CPU. I don't konw how do you do to recover this. I wrote :

NODE test
LABEL {node:this:name} %
TARGET C:/Apache2.2/htdocs/cacti/rra/lol_traffic_in_36.rrd
POSITION 212 399

I don't know for "name" what I should write.


It is ALWAYS {node:this:bandwidth_in} or {node:this:bandwidth_out} or {node:this:inpercent} or {node:this:outpercent} - depending on if you want the value or percentage, and in or out.

It looks like you are looking at an interface traffic rrd file though.

Sorry, I took a bad example ...

NODE test
LABEL {node:this:name} %
TARGET C:/Apache2.2/htdocs/cacti/rra/cool_cpu_54.rrd
POSITION 212 399

Must I do use bandwidth_in, bandwidth_out ... too ?

ALWAYS




You change the DS name in the TARGET, but the {} part will always be bandwidth_in or bandwidth_out etc as above.

If you check the cacti.log, you will see errors from WEATHERMAP if the DS name is incorrect, along with a list of valid DS names.

Thanks, I understood !

I wrote :

NODE test
LABEL {node:this:outpercent:%k} %
TARGET C:/Apache2.2/htdocs/cacti/rra/cool_cpu_55.rrd:-:cpu
POSITION 53 274

In result, I have a number like this : 143.47

But the percent should be between 0 and 100 !

I agree

If you run with DEBUG logging turned on for one poller cycle, then look in cacti.log, you should see some lines like:
RRD ReadData returning [...]

that should tell you what weathermap is reading from the rrd file. I guess it's possible that for a dual core CPU, you get a number from 0 to 200%...

If that's what is going on, then you should add
MAXVALUE 200
to the node, so the percentage is calculated with 100% as the value 200 (if you see what I mean).

I see what you mean. And I have a dual core CPU .
But I have one .rrd for each CPU ...

I used an other computer (Amd Sempron), and for the Cpu, I had 756 !
I verified, and I used the good file. Then, I opened the .rrd file with RRD Editor, and the values don't jibed with the values in weathermap ... In the file, I had the good values I think. For example :
9,2000000000E+01
9,2000000000E+01
9,3680000000E+01
9,5000000000E+01

I looked on the graph, and it's the good values.

Oh wait... add gauge: to the front of the TARGET - by default it multiplies by 8, because it assumes you have a byte-counter value, and you want bits/sec.

So that's:
TARGET gauge:C:/Apache2.2/htdocs/cacti/rra/cool_cpu_55.rrd:-:cpu
