Capacity: System Pool Bytes Used

This statistic shows the used bytes, in Gigabyte units, for the system pool capacity, including data, metadata, and snapshots, except for reservations. 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.

hostname:> analytics
hostname:analytics> datasets
hostname:analytics datasets> create syscap.bytesused


hostname:> analytics
hostname:analytics> worksheets
hostname:analytics worksheets> select worksheet-000
hostname:analytics worksheets worksheet-000> dataset
hostname:analytics worksheets worksheet-000 dataset \
(uncommitted)> set name="syscap.bytesused" 
hostname:analytics worksheets worksheet-000 dataset \
(uncommitted)> commit

When to Check System Pool Bytes Used

This statistic can be used as a threshold alert for the used system pool capacity in bytes. 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.
