I call dns,smtp,pop3,noconn,noping as a tag. So, is there any 'how-to' to add my own tag? Let say, my tag is 'roaming'. In the bb-host will be like this (for the host I want to do a 'roaming' test):
10.10.10.10 www.yyy.xxx # roaming
I already made the script, but I don't know how hobbitd will call my script. Should I just put it as an ext script?
The short answer:
If your script does all the work of generating a status message and sending it to Hobbit using the "bb" commandline tool, then you can just run it as an external script.
The long answer:
You don't say if your script is one that runs on each of your clients and reports a status for only that client, or if it's something that runs on a central server and generates a status for several hosts. That can make a difference:
client-side scripts generally don't need any kind of tags in the bb-hosts file; you just run them on the client, and they generate a status message. Hobbit picks up whatever status messages arrive, and puts them on the web display.
server scripts may need a tag in the bb-hosts file, if they have been written to look for one. It is fairly common to have server-side scripts that perform some custom test on a series of hosts, and you can use a tag in the bb-hosts file to tell your script which hosts it should test. But you don't have to; it depends on how you want to implement your script. If you want to use a tag in the bb-hosts file, your script should do something like this.
#!/bin/sh
Name of the column we generate
COLUMN=mytest
The tag we look for in the bb-hosts file
BBHOSTSTAG=mytest
bbhostgrep --no-extras $BBHOSTSTAG | while read L; do set $L HOSTIP=$1 HOSTNAME=$2 MACHINE=
echo $HOSTNAME | sed -e's/\./,/g'do your test against the host with IP $HOSTIP
COLOR=... # The color you decide MSG=... # The message text you pass back
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR
date$MSG" done
The "bbhostgrep" picks out those lines in the bb-hosts file that has your tag in them, and you can then get the IP-address and hostname for each of them. Using this tool is the best way, because it does all of the tricky parsing of the bb-hosts file for you - and it works if you start using include-files into the bb-hosts file, or your admin begins splitting up entries onto multiple lines etc.
