How does Prometheus deal with abnormal data and data loss situations?

Prometheus deals with abnormal data and data loss by using the following methods:

1. Data loss prevention: Prometheus avoids data loss by persisting time series data using a local disk as the default storage location, ensuring that data remains intact even in unexpected situations.
2. Abnormal data: Prometheus comes with built-in rules and alerting features to help users quickly detect and address abnormal data. Users can also define custom alert rules to trigger notifications when data is out of line.
3. Data recovery: Prometheus also provides mechanisms for data recovery, such as data backup and restore functions, to quickly recover data in case of data loss. Additionally, Prometheus also supports data replication and high availability configurations to ensure the security and reliability of data.

Overall, Prometheus ensures the stable operation of the system by handling abnormal data and data loss situations through methods such as data persistence and backup, monitoring and alerting of abnormal data, data recovery, and high availability configuration, to ensure that users can quickly identify and resolve issues.
