Recently while working on one of the test exadata machine came across one of the very useful tool to monitoring exadata system health. Being one of the most popular topics that customers talk about is the monitoring of your exadata health.
The best tool for this is the Exachk (see MOS Doc ID 1070954.1)
This document contains the current Exachk release.
The recommendation or advices for Exachk is to:
1) Run the exachk (at a minimum) quarterly, and after any changes are made to the configuration
2) ALWAYS run the current exachk. This script is periodically updated/improved upon so it is very important to be current
3) Keep track of any failures to ensure that you can identify any new items that appear in the report
4) A score of 80 or above is a good score for production. It is very rare to have a score that is 99+.
