How does Prometheus handle archiving and cleaning up monitoring data?

Prometheus typically utilizes Retention and Retention Policy to manage the archiving and cleaning of monitoring data.

Retention refers to the length of time that monitoring data is kept, and can be configured in the Prometheus configuration file. Once the data exceeds the retention time, Prometheus will automatically clean up this expired data.

Retention Policy is a more flexible data preservation strategy that allows different retention periods to be set based on different time frames and data granularities. By implementing a Retention Policy, monitoring data archiving and cleaning processes can be more finely controlled.

In addition, Prometheus also supports remote storage and backup, enabling monitoring data to be stored in a remote storage system or regularly backed up to a different storage medium to ensure the security and reliability of the data.

Overall, Prometheus offers a variety of features and flexible configuration options to help users effectively manage archiving and cleaning of monitoring data.
