Pool capacity is evaluated every few hours (after a new topology collection) to determine if a low pool capacity alarm should be generated, and to summarize the number of pools experiencing capacity pressure on the Environment Summary/Monitoring/Summary for Arrays and Filers.
Clicking on the array name will display a view that identifies the pools with Severe or High capacity issues. A low pool capacity alarm will have been generated for every pool that is not OK, if the low pool capacity rule is enabled.
The SanStorage Pools Capacity Summary Report summarizes the total and available capacity, and estimated time until full, for the pools or aggregates in the selected Storage devices. The report can be optionally limited to the pools or aggregates with thin-provisioned entities.
The rule StSAN E Pool Low Available Capacity with Email will be evaluated after every collection that provides new capacity information. A fatal alarm will be generated for every pool experiencing severe capacity pressure. A critical alarm will be generated for every pool experiencing high capacity pressure. A warning alarm will be generated for every pool included under the monitor count. No email will be generated for warning alarms.
These variables are used in pool capacity evaluation to compare to the estimated Time Until Full. For over-committed pools, they will generate alarms as Fatal/Critical/Warning. For pools that are not over-committed, they will generate alarms as Critical or Warning, based on the available capacity in the pool.
There variables are used to examine pool capacity when no estimated Time Until Full value is available, and when the Time to Full is very long. Critical or Warning alarms will be generated for pools that are not over-committed. Fatal and Critical alarms will be generated if the pool is over-committed.
