So you are using a custom script to monitor instead of hobbitclient-*.sh ?
This really isn't an option for me, since I have literally dozens of
servers that all have the same hobbit homedir, although I have written

It does not matter. You can still write an external script like this

[external]
        ENVFILE /path/to/local/etc/hobbitclient.cfg
        CMD /path/to/local/external/script
        LOGFILE /path/to/local/logs/external.log
        INTERVAL 5m

That will work just fine even though you are sharing same hobbit client

I tried that...2 problems:
1. I don't have a local place to store things (the homedirs are SAN, and I don't have permissions to use /usr/local and whatnot). 2. I tried similar to above anyway, using /tmp, and the client log fills up with errors because it cannot find the ext script to launch. To get around this, any ext scripts I write, I include a hostname check, such that they only run on the hosts I want. My wishlist item is that Hobbit would support an option to run ext tests via hobbitclients.cfg, but it will probably never be added due to security concerns :)
