[hobbit] Comma-separated lists of hostnames, etc. in hobbit-alerts.cfg is not documented

[jm54601 at yahoo.com]

Here's a script I used to convert bbwarnrules.cfg to hobbit-alerts.cfg.  It's far from perfect, but might help you save some labor.  We also used host groups and page groups fairly extensively in bbwarnsetup.cfg.  This script merges both.

#!/bin/bash
# Converts bbwarnrules.cfg to hobbit-alerts.cfg format
# TO DO: DAY and TIME
#BBWR=/usr/local/bb/etc/bbwarnrules.cfg
#BBWS=/usr/local/bb/etc/bbwarnsetup.cfg
BBWR=bbwarnrules.cfg
BBWS=bbwarnsetup.cfg
OUT1=/tmp/HGA.`date +%s`
HG='hg-'
DHG='$hg-'
PG='pg-'
DPG='$pg-'
#for i in `grep ^hg- $BBWR|tr ' ' '+'`
for i in `cat $BBWR | tr ' ' '+'`
do
if [[ $i == [h][g]* ]]
then
# HOST=`echo $i | tr '+' ' ' | awk -F\; '{print $1}'| sed -e s/$HG/$DHG/g`
HGA=`echo $i | awk -F\; '{print $1}'`
if [[ $HGA == *[+]* ]]
then
# echo handle multiple hostgroups
echo -n HOST=
for yy in `echo $HGA | tr '+' ' '`
do
grep -w $yy $BBWS|awk -F: '{print $2}' >> $OUT1
done
for xx in `cat $OUT1`
do
echo -n $xx,
done | sed s/.$//
rm $OUT1

Thanks for the suggestion.  I'll certainly give that some thought.  Comma-separated is just the easiest when it comes to converting my existing bbwarnrules.cfg file as I can just select the hosts and replace spaces with commas.  Going forward I had thought of using macros, but I'll look at PAGEs too.

I struggled with the same thing through a lot of trial and error.  On a related note, I highly recommend trying to get away from using a comma separated list as it's a nightmare to maintain.  I'm working toward using the PAGE token, where a list of hosts on a given page alerts a group, so you're effectively grouping your hosts based on the support team responsible.  There will still be exceptions, but if you can generalize alerts so all the hosts on a given page can alert the same way, you'll save time and avoid the possibility of a host not having an alert configured.  Just my 2 cents.

Comma-separated lists of hostnames in hobbit-alerts.cfg is not documented, so maybe we could add something like this (taken from  http://hobbitmon.sourceforge.net/docs/man5/hobbit-clients.cfg.5.html) to http://hobbitmon.sourceforge.net/docs/man5/hobbit-alerts.cfg.5.html:
        HOST=targetstring Rule matching a host by the hostname.  "targetstring"
        is either a comma-separated list of hostnames (from the bb-hosts file),
        "*"  to  indicate "all hosts", or a Perl-compatible regular expression.
        E.g.  "HOST=dns.foo.com,www.foo.com"  identifies  two  specific  hosts;
        "HOST=%www.*.foo.com  EXHOST=www-test.foo.com" matches all hosts with a
        name beginning with "www", except the "www-test" host. 
Adding an example that used the comma-separated syntax to http://hobbitmon.sourceforge.net/docs/hobbit-alerts.htmland hobbit-alerts.cfg (sample) files would also be good.
And, actually, maybe something to say that the comma-separated syntax can be used in all XXX= places (except, presumably, REPEAT) and also for the recipient.  One really shouldn't have to work this basic stuff out using:
$ ./bin/bbcmd hobbitd_alert --test 
! 
We definitely need some more complex examples.  Maybe someone who has a complex and varied hobbit-alerts.cfg can post some sanitized examples that someone can commit to SVN?
Many thanks, 
SebA
