RE: [hobbit] no graphs from mpstat

["Klomp, H." <klomph (at) nlr.nl>]

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,

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:

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

X.X.X.X  <hostname>      # TRENDS:*,mpstat:mpstatusr|mpstatsys|mpstatwt|mpstatidl

Subject: [hobbit] no graphs from mpstat

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.
