Hi all,
Before posting I carefully read the all the docs I could find on the matter, FAQs, HOWTOs, and the following strings:
http://www.hswn.dk/hobbiton/2006/10/msg00318.html
http://www.hswn.dk/hobbiton/2006/10/msg00326.html
http://www.hswn.dk/hobbiton/2008/09/msg00244.html
http://www.hswn.dk/hobbiton/2008/09/msg00265.html
So, I was able to slowly and painfully crawl along and write a couple of "hello world" scripts.
My server "ps" looks like this:
ezio# ps -ef | grep hobbitd_rrd | grep -v grep | grep -v hobbitd_channel hobbit 7929 7928 0 16:08 ? 00:00:00 hobbitd_rrd --rrddir=/var/lib/hobbit/rrd hobbit 7954 7953 0 16:08 ? 00:00:00 hobbitd_rrd --rrddir=/var/lib/hobbit/rrd --extra-script=/usr/lib/hobbit/server/ext/rrd_mon.sh --extra-tests=iostat --debug
Notice the "=" sign is there between --extra-script and the actual script name (see http://www.hswn.dk/hobbiton/2008/09/msg00357.html)
My extra script is so trivial I'm ashamed to post it, but it's good to check if it is going to be executed at all:
#!/bin/bash
TMPLOG="/tmp/$1.$2.out.$$" date >> $TMPLOG echo "$1, $2, $3" >> $TMPLOG cp $3 >> $TMPLOG 2>&1 exit 0
OK, nothing is created in /tmp, so, I'm assuming hobbit_rrd is NOT executing my extra script. Turning on the "--debug" option did not help much
What am I missing? Should I put all the fancy RRD-formatted-colon-separated "echoes" in my extra-script? (I wouldn't say so)
Ciao,
Ezio
