OK, so I've finally delved into the murky waters (ok so I had to make that sound scary and all fearsome and what not LOL) of writing my own Hobbit server extension script. And as part of the script, it collects data. I want to graph that data on hobbit. So I set up the NCV stuff... problem is that it doesn't create the RRD file correctly. Here's the relevant entries from hobbitserver.cfg:
TEST2RRD="cpu=la,disk,inode,qtree,memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp,time=ntpstat,vmstat,iostat,netstat,temperat ure,apache,bind,sendmail,mailq,nmailq=mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,qstat=ncv"
This defines which RRD files to include on the "trends" column webpage,
and the order in which they appear.
GRAPHS="la,disk,inode,qtree,memory,users,vmstat,iostat,tcp.http,tcp,netstat,mrtg::1,temperature,ntpstat,apache,bind,sendmail, mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,qstat"
Ok these columns are from qstat and are used to graph (I HOPE!) the
columns via rrd.
NCV_qstat="avgping:GAUGE,curplayers:GAUGE"
And that status message that gets sent is this:
qstat status for host 123.123.123.123 curplayers : 0 avgping : 0
IE my ext script does this:
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR date
${MSG} curplayers : $cur_players avgping : $avg_ping"
Where $MSG can be changed depending on circumstances.
However, when I dump the RRD file, I get this info:

Ok... well it seems that I wasn't allowed to have my message as the first line of the status report. Once I removed that, it collected the first data point. IE curplayers. But it's not collecting avgping. Is this correct? Or should I send each of these data points as a data message instead of in status?

AH HAH... my problem is solved!!!
Seems that I had to have an extra carriage return (or make the value(s) show up first in my status) for it to find TWO data points!

</ds>Which is EXACTLY what I wanted!!!! :) Might want to stress that Henrik. :) I had to do this in my ext script:
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`
curplayers : $cur_players
avgping : $avg_ping
${MSG}"Now if I hadn't sent ${MSG} it would have to look like this:
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`
curplayers : $cur_players
avgping : $avg_ping"
Now my next question.. LOL I'd like to have two SEPARATE graphs for this stuff... I tried this:
[qstat] TITLE Current Number of Players YAXIS # of Players DEF:curplayers=qstat.rrd:curplayers:AVERAGE LINE2:curplayers#00CCCC:Current Players COMMENT:\n GPRINT:curplayers:LAST: \: %5.1lf (cur) GPRINT:curplayers:MAX: \: %5.1lf (max) GPRINT:curplayers:MIN: \: %5.1lf (min) GPRINT:curplayers:AVERAGE: \: %5.1lf (avg)\n [qstat1] TITLE Average Ping YAXIS ms DEF:avgping=qstat.rrd:avgping:AVERAGE LINE2:avgping#00CCCC:Average Ping COMMENT:\n GPRINT:avgping:LAST: \: %5.1lf (cur) GPRINT:avgping:MAX: \: %5.1lf (max) GPRINT:avgping:MIN: \: %5.1lf (min) GPRINT:avgping:AVERAGE: \: %5.1lf (avg)\n
And that didn't work. Now if I moved the qstat1 stuff (minus title and yaxis) up into qstat.. I got one graph with two lines... I GUESS that's ok but.. ;)

And as a followup. Is there any way I can add some graphs from other hosts? IE a number of our game servers are on the same physical machine.
IE something like: 123.123.123.123 <--- Main IP 123.123.123.124 123.123.123.125 123.123.123.126
For the game servers on say .124 and .126 I'd also like the CPU/Mem graphs on the trends page also. Is this possible?
