This report provides an overview of host exception events and unavailability.

How to interpret the report

On the cover sheet, two pie charts show the number of hosts by host groups and host categories.

On the first page, the graphs show the evolution of exception events by day and by month. A radar graph provides the exception event distribution by host groups.

On the second page, the graph shows the maintainability and reliability of the host groups, as determined by an index based on MTRS and MTBF times.

Afterwards, a series of bar charts present information by host group, showing the evolution of exception events by host type. Finally, there is a comparison of the least maintainable and reliable host for each host group.
