* Alerting: Sanitize invalid label/annotation names for external alertmanagers Grafana's built-in Alertmanager supports both Unicode label keys and values; however, if using an external Prometheus Alertmanager label keys must be compatible with their data model. This means label keys must only contain ASCII letters, numbers, as well as underscores and match the regex `[a-zA-Z_][a-zA-Z0-9_]*`. Any invalid characters will now be removed or replaced by the Grafana alerting engine before being sent to the external Alertmanager according to the following rules: - `Whitespace` will be removed. - `ASCII characters` will be replaced with `_`. - `All other characters` will be replaced with their lower-case hex representation. * Prefix hex replacements with `0x` * Refactor for clarity * Apply suggestions from code review Co-authored-by: brendamuir <100768211+brendamuir@users.noreply.github.com> Co-authored-by: brendamuir <100768211+brendamuir@users.noreply.github.com> |
