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 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

Go to the Dashboard in the Grid Manager. Under Protocol Operations, view the values for S3 rate and Swift rates.
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).
