add rust server logs to the formats list - #1426
Conversation
WalkthroughAdds a new rust_server_logs format with three regex patterns to resources/formats.json and introduces a unit test validating extraction across sample logs in src/event/format/known_schema.rs. Changes
Sequence Diagram(s)sequenceDiagram
autonumber
participant L as Log Line
participant EP as EventProcessor
participant F as formats.json (rust_server_logs)
participant R as Regex Engine
L->>EP: submit raw_log
EP->>F: load rust_server_logs patterns
loop Try patterns in order
EP->>R: apply Pattern1 / Pattern2 / Pattern3
alt match
R-->>EP: named groups (timestamp, level, module, body, ...)
EP-->>L: extracted fields
else no match
R-->>EP: no match
end
end
note over EP: If matched, optional fields (logger_context, thread_id, line_number) present only when captured.

1469-1501: LGTM: adding rust_server_logs format is a solid extensionNew format entry and field sets align with existing conventions and should interop cleanly with the extraction pipeline.
