Live Monitoring
Stream logs and monitor tunnel health in real time
Log Viewer
Every running profile has a Monitor tab that streams cloudflared output in real time. The log viewer displays both stdout and stderr from the tunnel process, giving you full visibility into what's happening.
Logs are color-coded by level:
- INF (info) — Normal operations like connection establishment
- WRN (warning) — Non-critical issues like retry attempts
- ERR (error) — Failures that may require attention
The viewer auto-scrolls to the latest entry. You can scroll up to inspect earlier logs without losing new output.
Real-Time Streaming
FlareDeck captures output from the cloudflared child process as it runs. There's no polling or delay — logs appear as they're written. This is especially useful for:
- Debugging connection issues — See exactly when and why connections fail
- Monitoring traffic — Watch requests flow through the tunnel
- Catching errors early — Spot misconfigurations before they become problems
Tunnel Status Indicators
Each profile shows a status indicator in the sidebar:
| Status | Indicator | Description |
|---|---|---|
| Running | Green | Tunnel is active and healthy |
| Starting | Yellow | cloudflared process is launching |
| Stopping | Yellow | Tunnel is shutting down gracefully |
| Stopped | Gray | Tunnel is not running |
| Error | Red | Process exited with an error |
The status updates automatically based on the cloudflared process state and log output.
Health Checks
When a tunnel is running, FlareDeck monitors the cloudflared process health:
- Process alive — Checks that the
cloudflaredprocess hasn't crashed - Connection count —
cloudflaredestablishes multiple connections (typically 4) to Cloudflare's edge; FlareDeck tracks these via log output - Error detection — Repeated errors in the log stream trigger a status change
If a tunnel repeatedly fails to connect, check the Troubleshooting guide for common causes and solutions.
Common Log Messages
INF Starting tunnel tunnelID=abc-123The tunnel process has started.
INF Connection established connIndex=0 ...A connection to Cloudflare's edge network was established. Healthy tunnels typically show 4 connections.
ERR Unable to establish connection ... dial tcp: connect: connection refusedThe local service specified in an ingress rule isn't running or is unreachable.
WRN Retrying connection in up to 4s connIndex=0A connection was lost and cloudflared is attempting to reconnect.
