[hobbit] NCV problems still
Hi Tracy,
Thanks for the response. If you are expecting the number of variables to vary from one status message to the next then you need to write your own parsing script and store the variables in individual RRD's ala how the disk rrd's are built.
Fy first status message has a DEV line and a RUN line but it seems to only process the DEV line. It has me stumped. I'm almost ready to give up on the NCV functionality and write my own parsing script.
Cheers
Phil

I was only able to get multiple variables into an rrd by deleting the rrd and starting over, then it started saving all of the variables properly. I assume the rrd file can't really grow new variables. I haven't yet figured out how to graph all of them though.

I have absolutely no problems when I reproduce your setup. I've done it on the Hobbit demo site at http://www.hswn.dk/hobbit/servers/ - look at the bottom of the page for the "osiris.hswn.dk" host.
All of the config. files are online, you can see them via the "Demo Site" menu item. The changes I made were:
Add "pro4=ncv" to TEST2RRD in hobbitserver.cfg
Add "pro4" (and "ncv" if it's not there) to GRAPHS in hobbitserver.cfg
Add a new setting NCV_pro4="DEV:GAUGE,RUN:GAUGE" to hobbitserver.cfg
Kill the hobbitd_rrd processes so they restart and pick up the new hobbitserver.cfg settings
Define the [pro4] setting in hobbitgraph.cfg [pro4] TITLE Pro4 graphs YAXIS Seconds DEF:dev=pro4.rrd:DEV:AVERAGE DEF:run=pro4.rrd:RUN:AVERAGE LINE2:dev#00CCCC:DEV time LINE2:run#FF0000:RUN time COMMENT:\n GPRINT:dev:LAST:DEV time \: %5.1lf%s (cur) GPRINT:dev:MAX: \: %5.1lf%s (max) GPRINT:dev:MIN: \: %5.1lf%s (min) GPRINT:dev:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:run:LAST:RUN time \: %5.1lf%s (cur) GPRINT:run:MAX: \: %5.1lf%s (max) GPRINT:run:MIN: \: %5.1lf%s (min) GPRINT:run:AVERAGE: \: %5.1lf%s (avg)\n
Start sending status messages for the "pro4" status using this script (dummy data, cut-and-pasted from your mails):
#!/bin/sh $BB 172.16.10.2 "status osiris,hswn.dk.pro4 green
dateDEV : 57 RUN : 20 " exit 0

I don't actually expect them to change, I just was able to monitor a lot more than I had originally planned, and went from 1 variable to 28. The rrd is fine, I just haven't gotten around to figuring out what to do about graphing.

I had to enable debugging to find out why the rrd wouldn't take the new variables, but once I did the errors made it obvious. Do you have error logs? My errors included not having every variable listed correctly in NCV_afs in hobbitserver.cfg, as well as needing to start with a fresh rrd.
