If you are thinking about general monitoring - you can use Nagios regards, Marcin Przepiorowski On Tue, Dec 30, 2014 at 8:46 AM, Lothar Flatz <l.flatz@xxxxxxxxxx> wrote: Hi Edwin, my vote is on lab128 if you want a substitute for diagnostics and tuning pack.

At the time I also had access to the Toad DBA pack. This replicates some additional missing technology in standard edition e.g load testing and SQL tuning.
