What kind of monitoring are you looking for?

Generally what is out there is either

a) long term graphing and trend analysis (that lets you determine that you will need more disk space in 3 months) or

b) watching for a service to go down, in which case you send an email or SMS.

I am after both of these but also I need a way to aggregate a lot of log files and perform actions like "If there was no log entry X in the last N days send an email" or "If system A wrote N entries to database and system B did not process any in time T perform some action or raise an alarm". I would guess a kind of aggregating of events and running scripts based on what happened. All the systems could be modified to log to an additional place if needed.

I can't say I've used it, but this sort of sounds similar to what splunk (http://www.splunk.com/) does.
