How to solve the data coverage issue in Prometheus?

One way to solve the problem of data overwrite in Prometheus is to use external persistent storage to save the data. By writing Prometheus data to persistent storage, it ensures that the data will not be lost or overwritten. Additionally, setting a data retention policy for Prometheus can ensure that only the necessary data is kept, and expired data is regularly cleaned up.

Additionally, you may consider utilizing Prometheus’ remote storage feature to store data in a remote database instead of local storage, which can enhance data reliability and persistence.

Finally, regularly backing up data is also a way to address the issue of data loss. By regularly backing up data, you can recover the backed-up data in case of data loss or overwrite.
