Status & Diagnostics

Command	Description	Example
yerd ping	Check that the daemon is alive (prints pong).	yerd ping
yerd status	Show a snapshot of daemon, proxy, DNS, ports, CA, and PHP health.	yerd status
yerd doctor	Diagnose common problems and report findings.	yerd doctor
yerd doctor fix	Attempt safe, unprivileged repairs (e.g. restart a crashed FPM pool).	yerd doctor fix

yerd ping            # pong, if the daemon is up
yerd status          # one-screen health snapshot
yerd doctor          # report problems and remedies
yerd doctor fix      # apply safe automatic fixes, then list what still needs you

yerd status reports the daemon PID, uptime and RSS, version, TLD, the bound HTTP/HTTPS ports (flagging rootless fallback or an active macOS pf redirect), the DNS responder address, CA trust state and path, resolver install state, load average, site counts, and a per-version PHP pool listing (state, PID, listen socket, RSS, available update).

yerd doctor prints each finding with a severity mark (✓ ok, ⚠ warn, ✗ fail), a detail line, and a → remedy where one exists. yerd doctor fix first lists what it applied, then what still needs manual attention.

Exit codes for diagnostics

yerd doctor (and yerd doctor fix) exit 1 if any finding is Fail severity, otherwise 0. A Warn alone does not fail the exit code. This holds in both human and --json modes, so doctor is safe to use in CI gates.

If the daemon is unreachable, yerd doctor is special-cased: instead of the generic "daemon unreachable" error, it surfaces a synthetic Daemon not running Fail finding and exits 1, so a down daemon shows up as a doctor failure, consistently across --json and the exit code.

See the Diagnostics guide for an explanation of each check.
