[hobbit] Modem monitoring

[Smith, Jim]

Henrik,

You got me on the right track.  Here is what I have done to get this to
work like I wanted:

My external test "modemtest.sh" contains:
#!/bin/sh
BBLOCATION=modem bbtest-net --dns=ip

My hobbitlaunch.cfg has this added:
[modemtests]
        ENVFILE /home/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD $BBHOME/ext/modemtest.sh
        LOGFILE $BBSERVERLOGS/modemtest.log
        INTERVAL 15m

I added BBLOCATION="standard" and added the -test-untagged option to
bbnet.

I added a new service to bb-services:
[faxmodem]
   send "AT\r\n"
   expect "OK"
   options telnet

My bb-hosts file contains lines like this for the modems:
192.168.9.222    labfax1 # NET:modem faxmodem:3001 noconn

So far it seems to be working pretty well.  I started out with --debug
in my external test to see what was actually happening.  That was a big
help!

I'll probably keep messing around with this for a while to make sure it
is really doing what it appears to be doing.

Next I want to get the bbretest-net.sh working.  I'll try to figure that
part out on my own.  <grin>

Thanks a bunch!  This is great!

Jim Smith

You can use the "NET:..." definition in the bb-hosts file to split
up your network tests into two groups: Those that are for the modems,
and all the others. First setup your modem tests as a separate group
of tests:

* Change the entries in your bb-hosts file for these modems and
  add "NET:modem"
* Create a script ~hobbit/server/ext/modemtest with:
    #!/bin/sh
    BBLOCATION=modem bbtest-net --ping --check-response
  Remember to make it executable (chmod 755 ...)
* Add a new section to the ~hobbit/server/etc/hobbitlaunch.cfg
  file to run this script once an hour:
    [modemtests]
	ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
	NEEDS hobbitd
	CMD $BBHOME/ext/modemtest
	LOGFILE $BBSERVERLOGS/modemtest.log
	INTERVAL 1h

This runs your modem tests once an hour. Now, you also want to NOT
run them together with the standard network tests. To do that:

* Change ~hobbit/server/etc/hobbitserver.cfg and add 
    BBLOCATION="standard"
  This makes the BBLOCATION setting be "standard" by default.
* Change the CMD line in the [bbnet] section in hobbitlaunch.cfg
  and add the --test-untagged option:
    [bbnet]
	ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
	NEEDS hobbitd
	CMD bbtest-net --report --ping --checkresponse --test-untagged
	LOGFILE $BBSERVERLOGS/bb-network.log
	INTERVAL 5m
  The --test-untagged option means that there is an implicit
  "NET:standard" definition on all entries in the bb-hosts file,
  which do not have an explicit NET:... definition.

Henrik
