Indicates that the usage of a component corresponding to
a particular metric has crossed the threshold limit during
Components with a red status icon beside them ( )
the specified threshold duration. In such cases, the status
icon also appears as for the appropriate category in
the XP/P9000 Array Health section.
Can include the following: Components shown as black text
• The components whose usage corresponding to a
particular metric is at 95% of the threshold limit or
higher during the specified threshold duration. The status
icon in such cases appears as in the appropriate
category, if there are no other components that are over
utilized in that category.
•
The components whose usage corresponding to a
particular metric is within 95% of the threshold limit
during the specified threshold duration. The status icon
in such cases appears as in the appropriate
category, if there are no other components that are over
utilized or nearing the set threshold limits in that
category.
NOTE: You can sort the component records in the Statistics section based on their current state.
The critically utilized components are displayed first followed by those components whose usage
is nearing or within the set threshold limits.
For the Frontend, Cache, Backend, or MP Blade category, select components in the Statistics section
