Re: [hobbit] Another newbie needs help w/ custom graphs

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 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
