5 Understanding Analytics Statistics

Analytics statistics provide incredible observability into Oracle ZFS Storage Appliance, showing how the appliance is behaving, and how clients on the network are using it. While the statistics presented by Analytics might appear straightforward, there might be additional details to be aware of when interpreting their meaning. This is especially true for the purposes of performance analysis, where precise understanding of the statistics is often necessary.

To minimize service downtime in clustered systems, statistics and datasets are not available during failback and takeover operations. Data is not collected, and any attempt to suspend or resume statistics is delayed until failback and takeover operations have completed and data collection automatically resumes.
