Hi Janine,
I'm the author of Karma, and you're right it has not been updated in a
number of years. I tend to use Nagios (http://nagios.org) these days as
it has some really great features, and can monitor the whole enterprise,
run tests on remote servers, and is a generally great all-around
schedule/notification system. It will monitor ping, http, ssh, disk
partitions, logfiles with a builtin plugin, or with any external programs
(swatch is one I really like http://swatch.sourceforge.net/)
On the Oracle side it comes with a basic plugin to check that Oracle is
alive and the listener is up. However it is fully scriptable with any
language. Perl is ideal for this, as Jared and Mladen can attest. I have
some scripts I use, and was thinking of releasing a more general plugin
which can be configured to do just about any query, and check results. If
you're concerned about the overhead of reopening connections to Oracle
each time you to a db check, you can use mod_perl with Apache to make
connections persistent.
HTH,
Sean
