Re: [hobbit] custom rrd data graph

Well, I tried replacing all instances of pcpu_idle with pcpuIdle, restarted
server and client but still no rrd's.  Is there some way I can check to see
that the data is actually reaching the server?  I'm getting data and graphs
for load average, disk, memory utilization, etc.  The stuff that usually
shows up in trends, so I know the client can reach the host.

 I just went through a very similar situation in the last 4 days.  Some
things with underscores worked, some things didn't.  There was a suggestion
to put spaces between the DS and VALUE, which also had mixed results.



The final fix was to remove underscores from everything, and that solved
my problem across the board.  My users would have rather had the underscores
due to some naming similarities, however, they are living with it to get the
graphs J.  Funny how much power a graph has.

Hi all,

I've spent a good deal of time today perusing the archives and man pages
hoping to glean the answers to my problem of creating a custom rrd data (not
status) graph.  The process should be similar but darn near everything I've
seen deals with status graphs.

Here's the contents of my ext script on the client:

(stuff to put a value into /tmp/pcpu.txt)
$BB $BBDISP "data $MACHINE.pcpu
`cat /tmp/pcpu.txt`"


The contents of /tmp/pcpu.txt:

pcpu_idle : 97.16


On the server side of things I've modified the hobbitserver.cfg files'
TEST2RRD and GRAPHS lines to append "pcpu_idle=ncv".
I also have this line in the same file: NCV_pcpu_idle="pcpu_idle:GAUGE"

hobbitgraph.cfg also includes this definition:
[pcpu]
        TITLE ESX CPU Utilitization
        YAXIS % Used
        -u 100
        -r
        DEF:cpu_idl=pcpu.rrd:cpu_idl:AVERAGE
        CDEF:pbusy=100,cpu_idl,-
        LINE2:pbusy#00CC00:% CPU busy
        GPRINT:pbusy:LAST: \: %5.1lf (cur)
        GPRINT:pbusy:MAX: \: %5.1lf (max)
        GPRINT:pbusy:MIN: \: %5.1lf (min)
        GPRINT:pbusy:AVERAGE: \: %5.1lf (avg)\n

I don't have a pcpu.rrd file in the rrd/host directory which I would
expect to see.  I don't see any error messages in the client logs about not
being able to communicate.  Am I missing something obvious?  Any help would
be appreciated, thanks.
