Summary

netlify logs had no way to read Netlify Server logs.

This adds --source server, backed by the same server logs endpoint the UI's server logs page uses:

• History pages through the window. The API stops paging 10,500 lines back; when that cuts the window short the command warns (on stderr with --json).
• --follow polls every 2s with a 10s look-back, as the UI's live view does, and prints only lines it has not printed yet. It stops on a 401, 403 or 404 and reports other failures without stopping.
• --deploy-id and --url are rejected with --source server, since server logs are not tied to a deploy.

The source is opt-in; the default stays functions and edge functions.

📝 Summary

Summary by CodeRabbit

• New Features
  • View server logs alongside other log sources for a selected time range or in follow mode.
  • Server log entries show their source, actor, and severity, with historical results displayed oldest first.
  • A warning indicates when historical server log results are truncated, including when output is requested in JSON format.
• Usage Notes
  • The --url and --deploy-id filters cannot be used with the server log source.

The logs command now supports server logs as a source. Historical mode fetches paginated logs for the requested time range and reports when results are truncated. Follow mode polls for new server logs. The command rejects server requests combined with --deploy-id or --url. Tests cover retrieval, streaming, command behavior, and output. Documentation includes server-log examples.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Return a failure status when server following stops on an HTTP error.

If a server-only follow request returns 401, 403, or 404, streamServer stops polling and calls logError. That callback writes to stderr but does not mark the command as failed. With no remaining stream, the command can exit with status 0 despite retrieving no logs. Propagate permanent stream failure to the command's exit status. (raw.githubusercontent.com)
