I've made an ext script that parses mod_jk.log and computes a 5 minute average. I want this 5 minute average time sent to Hobbit and graphed (just graphed, so I'm using *data* instead of *status*).

I have done the following:
* Setup the ext script to be launched by the client.
* Added "modjk=ncv" to hobbitserver.cfg TEST2RRD section.
* Added ,modjk to hobbitserver.cfg GRAPHS section.
* Added "NCV_modjk="modjk:GAUGE" to hobbitserver.cfg
* Restarted Hobbit
* (I still need to do the graph definition, but I'm not bothering to do that yet because I'm not getting any rrd data)

I've let the client run the ext script several times, as well as running it by hand via "bbcmd", and I am still not seeing any rrd files show up in /data/rrd/hostname/

here is the tail end of the ext script:

MSG=`printf "mod_jk : %2.6f\n" $JKAVG`
$BB $BBDISP "data $MACHINE.modjk green `date` $MSG"
exit 0

Here is a running of the script, with the last line prefixed with "echo"  so that we can see what it's sending:
$ /bin/bbcmd ext/hobbit-mod_jk.sh/
2006-09-27 23:52:52 Using default environment file /users/monitor/local/hobbit/client/etc/hobbitclient.cfg
/users/monitor/local/hobbit/client/bin/bb 127.0.0.1 data cna-prod-app-28.modjk green Wed Sep 27 23:53:18 GMT 2006 mod_jk : 0.115922

If anyone can point out what I'm doing wrong, I would appreciate it.  This is my first time adding an NCV graph, and have many more to do, so want to be sure I get it right.

P.S. The $BBDISP is 127.0.0.1 because I'm using /pulldata/ mode.

  I've now inserted an extra linefeed, so again adding an echo temporarily so we can see whats going on, my output is:

  $ bin/bbcmd ext/hobbit-mod_jk.sh
  2006-09-28 04:15:54 Using default environment file /users/monitor/local/hobbit/client/etc/hobbitclient.cfg
  /users/monitor/local/hobbit/client/bin/bb 127.0.0.1 data cna-prod-app-28.modjk green Thu Sep 28 04:16:13 GMT 2006

  modjk : 0.139448

  Still no rrd file...hmmm

  The only difference from my seup. that I can see, is that I am using status and have defined the graph.

  And you can see the graph at:
  http://leopg9.no-ip.org/hobbit-cgi/bb-hostsvc.sh?HOST=leopg9&SERVICE=mailbox

As others have pointed out, the "mod_jk : N" must be on a separate line.
Also, "data" messages should not have anything but the hostname and
data-type on the first line. So try changing your script to do

VALUE=`printf "%2.6f\n" $JKAVG`
$BB $BBDISP "data $MACHINE.modjk

modjk : $VALUE
"

with a new-line right after the data identifier, and "modjk" (with no
underscore) on a line by itself.
