Expressions
Expressions is a powerful tool that allows formulating complex filters for playbook events. Playbook event filters use Common Expression Language (CEL).
The Common Expression Language (CEL) is a non-Turing complete language designed for simplicity, speed, safety, and portability. CEL's C-like syntax looks nearly identical to equivalent expressions in C++, Go, Java, and TypeScript.
Examples:
filter: check.type == 'http'
filter: check.type == 'http' && summary.failed > 3
Context
| Field | Description | Schema |
|---|---|---|
check | Check referenced by the event | Check |
summary | Check 1h summary of pass/faill/latency | |
component | Component referenced by the event | Component |
