Regular expressions
Regular expression syntax and glob syntax are not interchangeable. Chronosphere Observability Platform supports only one of these query matching patterns in supported areas of the product. For example, drop rules support glob syntax, whereas recording rules support regular expression syntax.
All regular expressions in Prometheus use RE2 syntax (opens in a new tab). Chronosphere Observability Platform supports RE2 syntax compatibility with Prometheus for queries using regular expressions in the following areas:
- Changes Explorer
- Dashboards
- Lens configuration
- Metrics Explorer
- Monitors
- Muting rules
- Recording rules
- Trace Explorer
Because the implementation of this parser is customized, the syntax might vary in some instances.
