Bert,

If "rrd_data.pl" is an external processor, it does not send data to RRD directly -- it simply emits the commands needed for the Hobbit process to update the RRD. Based on what you posted, I think you are on the right track -- the rrd_data.pl script is not parsing the test data in order to get data for multiple CPU's, so it is not issuing the proper commands to update multiple RRD's. I suspect that the person who wrote this section of the script probably assumed there would only be one CPU reported, or only the aggregate needed to be graphed. Not a bad assumption, but it is not working for you.

Since "rrd_data.pl" is a custom script, you will have to go back to the person who wrote the script to get them to update it for you, or you will need to update it yourself. What you will need to do (in the section that parses this test) is update the code to track multiple CPU's and then have it loop through them to generate the RRD commands for each CPU so the right RRD's are created/updated. Then you need to double check your Hobbit graph definition to make sure that it can handle multiple CPU's as well.

Good luck!

Thanks for the input, but all you mentioned is implemented. 
 
It looks like the rrd_data.pl isn't sending the data to the rrd

files. How can I check that ? When I run the rrd_data.pl script manually with the hobbit_mpstat.hostname.send as input file using the command server/ext/rrd_data.pl sodn034u mpstat client/tmp/hobbit_mpstat.sodn035u.send

I get the following output: 
 
DS:CPU:GAUGE:600:0:32
DS:usr:GAUGE:600:0:100
DS:sys:GAUGE:600:0:100
DS:wt:GAUGE:600:0:100
DS:idl:GAUGE:600:0:100
mpstat.CPU2.rrd
::::

 
I'm also puzzled by the name of the RRD file, since there is

only one rrd file created (mpstat.CPU2.rrd) I would expect that there should be 2 data files, one for each cpu, called mpstat.CPU.0.rrd and mpstat.CPU.1.rrd Regards, Bert Klomp

	A couple of things to check:

	 

	In the hobbitlaunch.cfg ensure that in the --extra-tests

for the "rrdata" section has "mpstat" listed, also the--extra-script points to the rrd_data.pl script. It probably does since you are creating the rrd data files....

	In the hobbitserver.cfg, ensure that under the TEST2RRD

"mpstat" is listed., also under the "GRAPHS" section.

	Then under the hobbitgraph.cfg file:

	 

	[mpstatusr]

	        GPRINT:idl at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

	 

	 

	 

	 

	Finally, in the bb-hosts file, ensure you have a host

like:

	X.X.X.X  <hostname>      #

TRENDS:*,mpstat:mpstatusr|mpstatsys|mpstatwt|mpstatidl

	I'm trying to setup mpstat to monitor systems with

multiple cpu's, but the graphs are not created.

	Can someone help me with this ? 

	 

	The information is send from the client to the server

and in the rrd data directory I have a file called

	mpstat.CPU2.rrd 

	but there are no values in the last ds (see example) 

	       <ds>

	                <name> CPU </name>

	                <type> GAUGE </type>

	                <minimal_heartbeat> 600

</minimal_heartbeat>

	                <min> 0.0000000000e+00 </min>

	                <max> 3.2000000000e+01 </max>

	 

	                <!-- PDP Status -->

	                <last_ds>  </last_ds>

	                <value> NaN </value>

	                <unknown_sec> 241 </unknown_sec>

	        </ds>

	 

	 

	the contents of the hobbit_mpstat.hostname.send file is 

	CPUs: 2

	CPU0usr: 17.18

	CPU0sys: 1.34

	CPU0wt: 0.06

	CPU0idl: 81.31

	CPU1usr: 26.16

	CPU1sys: 1.40

	CPU1wt: 0.06

	CPU1idl: 72.29

	 

	And I have copied the rrd_data.pl from the shire and

can't find a typo in it.

	Any suggestions would be appriciated. 

	 

	Regards, 

	 

	Bert Klomp

	 

	 

Anna, sorry my answer was confusing. I would change my answer to "you need to contact the people who maintain mpstat for assistance".

In my own environment, I have a generic script that handles the graphing needs for all of my custom scripts, so my suggestion was based on what I know to be true about generic graphing under Hobbit.

Hi Greg, the mentioned custom script ( rrd_data.pl ) seems to be a part of the initial release of mpstat dated 2006-11-26 . Therefore Your answer confuses me.
