Database monitoring tools

Hi list,

We´ve been , for several years , monitoring and
administering our Oracle databases with custom-made
SQL scripts. 

Using those scripts we are able to proactively avoid
possible problems and everything works fine ,
performance is good , no one is complaining.

But , I don´t know why (maybe to show some nice hit
ratios graphs to CIO) , management decided that we
need a GUI tool to monitor our databases. I tried to
deceive him from the idea , because we are a small
shop (+- 10 instances , 50 Gb the largest one) and
such tools are expensive , etc. But all my arguments
were not sufficient to change his mind.

So , we are evaluating GUI tools and we´ve already
looked at:
- BMC Patrol
- Quest Central
- Embarcadero 
- OEM (with diagnostic , performance and change
management packs)

Funny , now management agrees with me and said that
all they are expensive tools.

So , I wish to know what you guys are using to monitor
and administer your databases , if there is
open-source monitoring tools (I´ve tested one called
VROOM but , in my opinion , it su**s) and what you
think about such tools. Maybe , with other points of
view I can make him (the manager) to decide to keep
using our scripts or dig in the pocket and buy the
necessary tools.

Sorry for the long message and thanks in advance.
Regards,
Antonio Belloni
