Brilliant detective work Dan.  I am trying something similar, but 
haven't had the good luck that you enjoy.

Here is the status message being produced for a column called pg_util 
(Page Utilization):

status vm1.pg_util green 12 Nov 2005 10:55:57  Page Utilization  OK
pg_util : 1

TEST2RRD contains 'pg_util=ncv' (it's not at the end, does it need to 
be?) and

NCV_pg_util="pg_util:GAUGE"

I've disabled the code in the extra script for this test and removed it 
from the --extra-tests list.  I've verified with ps that hobbitd_channel 
and hobbitd_larrd aren't using them anymore.  I still have a custom 
graph defined for this test, is that allowed using NCV or doesn't it care?

Ok, I found the issue.

Though I've written dozens of bb clients, I've never come across
exactly how BB expects the information. This might be hobbit specific
however. In my original email, I stated I was sending the data from my
script like:

home/monitor/bb/bin/bb 1.2.3.4 "status iron1-mgmt.Memoryutil green
Memoryutil : 11"

This is not the correct way to do this hobbit-wise. You need to put a
\n in between the color status and the data you're pushing via ncv.
That is:

home/monitor/bb/bin/bb 1.2.3.4 "status iron1-mgmt.Memoryutil
green\nMemoryutil : 11"

Perhaps it's just my interpretation, but I think we should reword the
documentation to explicitly say we do not need to do any
--extra-script or --extra-tests if one is using ncv.

Finally, I perused a lot of the man pages and code for the past few
hours, and only found one error - and that was a spelling error. In
~hobbit/server/etc/hobbitgraph.cfg, temperature is misspelled:
# comment out the [tempeature] section above, and

I'm now using ncv for collecting 8 datapoints and it appears to
collect and graph data flawlessly. Thanks for the solid implementation
Henrik.

Sorry for the hasty followup, but does anyone have any advice?

Thanks

Hello All,

I've read every post on the list, but still cannot figure out why I
can't get rrds to appear.

I've written a custom script that does something like:

/home/monitor/bb/bin/bb 1.2.3.4 "status iron1-mgmt.Memoryutil green
Memoryutil : 11"

On 1.2.3.4 (server), my hobbitserver.cfg has this:

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,Memoryutil=ncv"

The reason the test is memoryutil is because it's memory utilization
gotta via snmp for an ironport device.

My interpretation of the hobbitd_rrd.8 page, and this post:
http://www.hswn.dk/hobbiton/2005/06/msg00261.html
gives me reason to believe that I don't have to do anything but have a
script pass bb a "$test (=|:) value" value, and tell TEST2RRD
"$test=ncv", and I'd be graphing in no time. However, my
~hobbit/rrd/$hostname/ still doesn't have a $test.rrd.

Am I missing something? Doing something wrong? Assuming some things I
shouldn't be? Anyone have the ncv stuff working?

Thanks

Dan
