This statistic shows the used percentage of the system pool capacity based on the raw pool size. It is used as a threshold alert and cannot be displayed in a graph. Unlike other statistics, it is updated every five minutes instead of every second.
To create this capacity alert in the CLI, navigate to the analytics and datasets context. If using worksheets, navigate to analytics, the desired worksheet, and then the dataset context. For datasets, use the "create" command. For worksheets, use the "set name" command. Below, the "\" character denotes a line break.
clownfish:> analytics clownfish:analytics> datasets clownfish:analytics datasets> create syscap.percentused
OR
clownfish:> analytics clownfish:analytics> worksheets clownfish:analytics worksheets> select worksheet-000 clownfish:analytics worksheets worksheet-000> dataset clownfish:analytics worksheets worksheet-000 dataset \ (uncommitted)> set name="syscap.percentused" clownfish:analytics worksheets worksheet-000 dataset \ (uncommitted)> commit
This statistic can be used as a threshold alert for the used system pool capacity in a percentage. If the threshold is exceeded and the alert is triggered, you can mitigate the situation before the system pool becomes too full and performance is impacted.
None.
See Capacity: System pool bytes used for a threshold alert, in bytes, for the system pool used capacity.
