Explain how alerts are classified and prioritized in monitoring systems.

In monitoring systems, alerts are classified by importance level and problem type to quickly identify which incidents require immediate attention and which can be addressed later. The following priority levels are usually distinguished:

• Critical — failures leading to complete service unavailability or data loss.
• High — significant issues affecting performance or functionality.
• Medium — problems that do not affect service operation but require attention.
• Low — informational notifications or warnings.

Classification can be based on:

• Metric type (CPU, memory, network).
• Alert source (server, application).
• Time of occurrence and duration of the problem.

Prioritization helps operators respond quickly to the most critical incidents, reducing downtime and improving service quality.
