Sensu Go Severity Filter

TravisCI:

The Sensu Go Severity Filter is a Sensu Event Filter that
filters Sensu Go Events by Check status severity (ok, warning,
critical, unknown).

This Filter Asset implements the Sensu 1.x built-in Handler
severities filter logic.

Configuration

Configure filter definitions

Define one or more filters with sensu-severity-filter as a runtime
asset and using the has_severity function in a filter expression.
The following example shows a filter which will allow events with a
critical check severity:

---
type: EventFilter
api_version: core/v2
metadata:
  name: only_critical
  namespace: default
spec:
  action: allow
  runtime_assets:
    - sensu-severity-filter
  expressions:
    - has_severity(event, "critical")
