[hobbit] custom rrd data graph

[Jeffcoat, Al]

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 :-).  Funny how much power a graph has.

Subject: [hobbit] custom rrd data graph

 

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.
