RRD graphs appearing in trends but not in Devmon columns?
list Richard Finegold
I'm happily getting graphs for if_load and temp for Cisco routers, but the graphs are only appearing in the trends column. RRD graphs are appearing in Devmon-checked memory and cpu columns, but presumably that's due to them using standard text instead of specific Devmon syntax. I'm using "if_load=devmon,temp=devmon" in TEST2RRD in hobbitserver.cfg, as documented in Devmon's docs/GRAPHING, should that be working? Also "if_load::1,temp" in GRAPHS. I'm not sure, because the man page for hobbitserver.cfg suggests a "bb-hostsvc.cgi(1)" man page, which doesn't seem to exist. http://www.hswn.dk/hobbit/help/manpages/man5/hobbitserver.cfg.5.html#lbAM Ah, it's been partially renamed to hobbitsvc.cgi(1). That man page only seems to address "TEST2RRD=test,test", not the optional =RRDSERVICE syntax in hobbitserver.cfg(5). devmon-0.3.1-beta1, xymon-4.2.3-RC1. I haven't applied patches, because I thought they were both already patched for each other. I'm sure I'm missing something simple (perhaps a TEST2RRD parsing patch).

It's definitely an issue in the TEST2RRD parsing. As soon as I remove "=devmon", the graphs appear. But when it's removed, the rrd files aren't updated. I'm guessing 4.2.3-RC1's "lib/hobbitrrd.c" needs to be altered, but I'm not sure how -- the lines from hobbit-4.2.0-devmon-complete.patch are present in it, and the same text is in 4.3.0's lib/hobbitrrd.c in svn. Or perhaps my rrd is incorrect, but that seems unlikely because the graphs show in the trends column and display correctly. I have rrd filenames like if_load.Gi0_0.rrd. Until this month I was using '-extra-tests=if_load --extra-script=$BBHOME/ext/devmon-rrd.pl' for [rrddata] in hobbitlaunch.cfg, might that have a lingering effect? Any advice would be appreciated.
