It worth reading CEL official docs to learn about the language and its syntax.
Keep utilizes CEL (Common Expression Language) as a powerful and flexible tool to evaluate and filter alerts against predefined rules. CEL enables users to write precise expressions that define conditions under which alerts are processed, displayed, or acted upon. This capability enhances alert management by allowing granular control over visibility and response to incoming alerts.
Alerts are dynamically evaluated against CEL expressions to determine which alerts meet the specified criteria. This real-time filtering ensures only the most relevant alerts are surfaced.
