Data retention policy

You can configure data retention for each service. By default only traces, spans, and db query statements that satisfies the default values will be saved and shown in APM dashboard. If you have configured anything for a service, then everything gets saved as per the configured values.

note

The number of days we store data collected is by default 7 days for traces and 90 days for metrics.

By default all error traces and error spans are saved. The default values are:

  • default traces over 300 ms latency
  • default db query statements over 80 ms latency
  • default maximum number of spans in a trace that are saved is 200
