Metric Extensions can be defined on any target: hosts, databases, and so on.
What is most valuable?
The most valuable features are the Metric Extensions & Advanced Threshold management.
Extend Oracle's monitoring capabilities to monitor conditions specific to your IT environment
Provides a comprehensive view of your environment
Create metrics on any target type
Can be defined on any target:
EM is a one-stop shop used to manage and monitor the entire Oracle E-Business Suite, BI and EPM infrastructure in our company. So, in our BI environment, we wanted to run a script to kill sessions which are running over 60 minutes and wanted to track and tune those sessions. We used Metric Extensions for the same.
Advanced Thresholds allow you to define and manage alert thresholds that are either adaptive (self-adjusting) or time-based (static).
Adaptive thresholds are thresholds based on statistical calculations from the target's observed behaviour (metrics).
Time-based static thresholds are user-defined threshold values to be used at different times of the day/week to account for changing target workloads.
We used time-based threshold settings for weekday and weekend load on various environments. This way we could fine tune the alerts for varying loads.
How has it helped my organization?
It gives an end-to-end view of our complex IT infrastructure and its health in real-time.
What needs improvement?
The Adaptive Settings descriptions could be clearer. 95% percentile, etc. is not clearly specified.

I have used it for over five years.
What was my experience with deployment of the solution?
I have not encountered any deployment issues.

Technical support is good.
How was the initial setup?
Initial setup was pretty straightforward.
What about the implementation team?
An in-house team implemented it.
What was our ROI?
It reduced the number of incidents; we could predict failures.
Which other solutions did I evaluate?
Before choosing this product, we evaluated Quest/Toad, but it did not do end-to-end monitoring across the stack of products.
What other advice do I have?
It is one of the best, state-of-the-art products from Oracle; truly a single pane of glass to manage IT infrastructure.
