@Abhishek00810 Thank you for your contribution! You noted in your description that this closes issue #835. Is the -o flag working as expected? |

@chaptersix Yes, the -o flag works as expected. I verified locally that when --output json is used, these startup logs are automatically suppressed. This is because the CLI's Printer implementation explicitly ignores Printlnf calls when in JSON mode. This behavior ensures that integration tests using -o json receive valid, clean JSON without the startup banner, satisfying the requirement from issue #835. |

What was changed
Updated the local server startup log messages to explicitly include the "Temporal" prefix.
Server: ...->Temporal Server: ...UI: ...->Temporal UI: ...Metrics: ...->Temporal Metrics: ...Why?
To address the ambiguity mentioned in issue #835 where users (especially in multi-service local environments) could confuse Temporal's startup logs with their own application's logs. This clarifies exactly which ports belong to the Temporal development server.
Checklist
Closes [Feature Request] Allow server startup logging to be disabled or rewritten #835
How was this tested:
Ran the server locally using
go build ./cmd/temporal && ./temporal server start-dev --headlessand verified the console output matches the new format.No.
