Collecting data

After you have defined the problem and have assessed its risk and impact, collect data for analysis. The type of data that is most useful to collect depends upon the nature of the problem.

Type of data to collect Why collect this data Instructions
Create timeline of recent changes Changes to your StorageGRID system, its configuration, or its environment can cause new behavior.
Review alerts and alarms

Alerts and alarms can help you quickly determine the root cause of a problem by providing important clues as to the underlying issues that might be causing it.

Review the list of current alerts and alarms to see if StorageGRID has identified the root cause of a problem for you.

Review alerts and alarms triggered in the past for additional insights.

Monitor events Events include any system error or fault events for a node, including errors such as network errors. Monitor events to learn more about issues or to help with troubleshooting.
Identify trends, using chart and text reports Trends can provide valuable clues about when issues first appeared, and can help you understand how quickly things are changing.
Establish baselines Collect information about the normal levels of various operational values. These baseline values, and deviations from these baselines, can provide valuable clues.
Perform ingest and retrieval tests To troubleshoot performance issues with ingest and retrieval, use a workstation to store and retrieve objects. Compare results against those seen when using the client application.
Review audit messages Review audit messages to follow StorageGRID operations in detail. The details in audit messages can be useful for troubleshooting many types of issues, including performance issues.
Check object locations and storage integrity If you are having storage problems, verify that objects are being placed where you expect. Check the integrity of object data on a Storage Node.
Collect data for technical support Technical support might ask you to collect data or review specific information to help troubleshoot issues.
