Establishing baselines

Baseline information is operational data during normal system operations that provides clues that can help you solve problems.

You can gather useful baseline information using the StorageGRID Webscale system:

Property Value How to obtain
Average storage consumption

_____________/consumed/day GB

_____________/consumed/day %

Go to the Dashboard in the Grid Manager, and click graph icon for one of the Available Storage charts.

Find a period where the operation is fairly stable and estimate the daily storage consumption rate in bytes and in percentage.

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

Rate of S3/Swift Operations

_____________ Operations/s

Select Support > Grid Topology. Then, select Overview > Main.

Under API Operations, view the value for S3 Operations - Rate or Swift Operations - Rate.

Failed S3/Swift Operations

_____________

Select Support > Grid Topology. Then, select Overview tab > Main.

Under API Operations, view the value for S3 Operations - Failed or Swift Operations - Failed.

ILM Evaluation Rate

_____________ objects/second

Select Nodes > deployment > ILM. Choose a range (1 hour, 1 day, 1 week, 1 month, 1 year, or Custom). Hover your cursor over the ILM Queue graph to view the Evaluation Rate.

Average Query Latency

_____________ milliseconds

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

Failed Queries

_____________

Select Nodes > Storage Node > Objects. In the Queries table, view the value for Queries - Failed (timed-out).

Failed Queries for Consistency Level Unmet

_____________

Select Nodes > Storage Node > Objects. In the Queries table, view the value for Queries - Failed (consistency level unmet).
