logsink compatible with gcp cloud run log parser ...?

[breathe]

Is there a log sink that outputs logs in a format that can be directly understood by gcloud?

From a little googling' I'm failing to find anything that directly documents how to induce google's own cpp logger api to output messages that are directly understood by gcp services like cloud run (where an agent with custom log format parsing capability) is not used.

Even if I can configure a logging agent somehow with custom parsing logic -- I'd much rather have such custom log format parsing logic in the mix anyway and just configure my logger to directly output information in the expected (non-lossy) format ...
