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.

 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

The problem comes from that your setup should read as :

TEST2RRD="$TEST2RRD,pcpu=ncv"
                    ^-- match the name of the status
NCV_pcpu="pcpu_idle:GAUGE"
    ^-- same thing here

I don't quite follow Charles.  Here's the relevant lines from my hobbitserver.cfg file:

TEST2RRD="cpu=la,disk,inode,qtree,memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp,time=ntpstat,vmstat,iostat,netstat,temperature,apache,bind,sendmail,mailq,nmailq=mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,files,procs=processes,ports,clock,lines,pcpuIdle=ncv" 

NCV_pcpuIdle="pcpuIdle:GAUGE"

The message I'm sending from the client is a data message, not a status message.  This is what's coming from my client via an ext script running every 5 minutes:

$BB $BBDISP "data $MACHINE.pcpu
`cat /tmp/pcpu.txt`

what I'm telling is that the name after "$MACHINE" must match the name
used in TESTS2RRD and NCV_foobar. I think you're mixing the name of a
status (or data) report (here "pcpu") and the name of a particular line
(or data source, or DS) in the body of that status/data message.

Ahhhh, that makes sense.  Changing my client script to:

$BB $BBDISP "data $MACHINE.pcpuIdle
`cat /tmp/pcpu.txt`
"

caused the rrd's to be created and populated with data.

The change suggested by Charles Jones was helpful as it caused a link to
appear on my trends page where there was no representation of my data at
all, but not the actual graph.  The link doesn't produce any graphs either,
but I'm getting closer.  I remember reading about that elsewhere in the
forums so I'll go research that a bit.  Thank you all very much for the
assistance.

As a final message I was able to resolve my broken graph.  The graph
definition in my hobbitgraph.cfg file was listing an incorrect .rrd file.
Adhereing to Mr. Goyard's earlier suggestion I changed the def line to
reflect the actual rrd file name ( pcpuIdle.rrd) and *poof* graph appeared
in trends.  Thank you again.
