Establishing baselines

You can establish baselines for your system by recording the normal levels of various operational values. In the future, you can compare current values to these baselines to help detect and resolve abnormal values.

Property Value How to obtain
Average storage consumption

_____________ GB consumed/day

_____________% consumed/day

Go to the Grid Manager. On the Nodes page, select the entire grid or a site and go to the Storage tab.

On the Storage Used - Object Data chart, find a period where the line is fairly stable. Hover your cursor over the chart to estimate how much storage is consumed each day

You can collect this information for the entire system or for a specific data center.

Average metadata consumption

_____________ GB consumed/day

_____________ % consumed/day

Go to the Grid Manager. On the Nodes page, select the entire grid or a site and go to the Storage tab.

On the Storage Used - Object Metadata chart, find a period where the line is fairly stable. Hover your cursor over the chart to estimate how much metadata storage is consumed each day

You can collect this information for the entire system or for a specific data center.

Rate of S3/Swift operations

_____________ operations/second

Go to the Dashboard in the Grid Manager. In the Protocol Operations section, view the values for S3 rate and the Swift rate.

To see ingest and retrieval rates and counts for a specific site or node, select Nodes > site or Storage Node > Objects. Hover your cursor over the Ingest and Retrieve chart for S3 or Swift.

Failed S3/Swift operations

_____________

Select Support > Tools > Grid Topology.

On the Overview tab in the API Operations section, view the value for S3 Operations - Failed or Swift Operations - Failed.

ILM evaluation rate

_____________ objects/second

From the Nodes page, select grid > ILM.

On the ILM Queue chart, find a period where the line is fairly stable. Hover your cursor over the chart to estimate a baseline value for Evaluation rate for your system.

ILM scan rate

_____________ objects/second

Select Nodes > grid > ILM.

On the ILM Queue chart, find a period where the line is fairly stable. Hover your cursor over the chart to estimate a baseline value for Scan rate for your system.

Objects queued from client operations

_____________ objects/second

Select Nodes > grid > ILM.

On the ILM Queue chart, find a period where the line is fairly stable. Hover your cursor over the chart to estimate a baseline value for Objects queued (from client operations) for your system.

Average query latency

_____________ milliseconds

Select Nodes > Storage Node > Objects. In the Queries table, view the value for Average Latency.
