Metrics are numeric samples of data collected over time. They can measure infrastructure, such as operating system performance or disk activity, application performance, or custom business and operational data that is coded into your organization’s applications.
Metrics are an effective tool for monitoring, troubleshooting, and identifying the root causes of problems. They can help your organization:
- Gain end-to-end visibility into application performance.
- Track key performance indicators (KPIs) over time.
- Determine if an outage has occurred and restore service.
- Determine why an event occurred and how it might be prevented in the future.
Sumo does not ingest metric data that is more than one week old.
Metrics data is stored in Sumo Logic as raw, one minute, and one hour resolutions. It's retained according to the following retention policy:
|Data Type Retained||Retention Period|
|1 minute resolution||30 days|
|1 hour resolution||1 year|
For historical rollups (1 minute and 1 hour) Sumo calculates the max, min, avg, sum, and count values for a metric per minute or hour.
