[hobbit] Another newbie needs help w/ custom graphs

26 Sep 2008

      I took a look at a NCV that I have set up and in hobbitserver.cfg GAUGE
is capitalized.  RRD may be picky about case so try:
NCV_weblogic="usedheap:GAUGE"

Hi Rich,
I added that and bounced Hobbit, but it didn't seem to help.
Any other thoughts?

Brian,
In addition to adding 'weblogic=ncv' to TEST2RRD, you also have to add
'weblogic' (without =ncv) to GRAPHS.
Remember to bounce Hobbit after the change as it only processes the file
at startup time.

I've been working with Hobbit for all of a couple of weeks now,
although
I have some limited exposure to Big Brother in a previous life...
In order to learn the tool better, I wrote a simple custom monitor
that
watches Heap usage in an application server.  This seems to be
collecting data fine, but now I want to figure out how to graph this
information in an rrd graph.
Here's where I stand.

I have a column called "weblogic" in Hobbit.

When you click on that column for a given host, you see a field
called
"used_heap"

I edited hobbitserver.cfg and added a piece at the end of the
TEST2RRD
line:   weblogic=ncv

I also added a line to the same file:
NCV_weblogic="usedheap:Gauge"

I I'm generating a file called weblogic.rrd in
../data/rrd/<HOSTNAME>

But, when I go to the weblogic column, at the bottom of the page there
...
is a space where the graph should be that says "hobbit graph
ncv:weblogic"  No graph.
I THINK everything is ok up to this point, but then comes the
hobbitgraph.cfg file, and I have to be honest, I really don't
understand
this file at all and haven't come across a good explanation yet, so
I'm
open to someone telling me to go read some website before I post, if
it's glaringly obvious. I used some other files and the examples I
found
online to come up with this...
[weblogic]
    TITLE Heap Usage

    YAXIS Bytes

    DEF:heap=weblogic.rdd:usedheap:AVERAGE

    LINE2:heap#00CCCC:Heap Used

    COMMENT:\n

    GPRINT:heap:LAST:Heap Used \: %5.1lf%s (cur)

    GPRINT:heap:MAX: \: %5.11f%s (max)

    GPRINT:heap:MIN: \: %5.11f%s (min)

    GPRINT:heap:AVERAGE: \: %5.11f%s (avg)\n
I could use some help getting this graph going, and even explaining
the
entries in the hobbitgraph.cfg file if anyone has the patience to help
...
walk me through this.

Brian
