Logs
Tails the OTel logs from a wendy-agent, rendering them in the terminal. By default it shows all apps and the agent's logs.
Tails the OTel logs from a wendy-agent, rendering them in the terminal. By default it shows all apps and the agent's logs.
With --app, you can filter on a per-app basis. You can also set a minimum log level using, for example, --level error.
If you provide --json, the output will be JSONL, one line per log statement.
To inspect the device's kernel ring buffer (dmesg) instead of container/agent logs, use wendy device os-logs.
Flags
| Flag | Description |
|---|---|
--app <name> | Only show logs from the named app. For multi-service apps this also includes each service container's logs, so crash output from a crash-looping service member is reachable with --app <appId>. |
--service <name> | Only show logs from the named service. |
--level <level> | Minimum log level: trace, debug, info, warn, error, or fatal. Defaults to info when neither --level nor --min-severity is given, so kernel dmesg debug/trace output stays hidden unless you ask for it. |
--min-severity <n> | Minimum OTel severity number; a numeric alternative to --level. |
--tail <N> | Request the last N stored log batches matching the active filters before following new output (default 0). The window counts only batches that survive --app/--service/--level, so other apps logging at high volume on the same device cannot push the requested app's logs out of the requested window. |
--no-follow | Print the logs the device replays and exit instead of following new output. Combine with --tail <N> to get the last N matching batches, e.g. wendy device logs --app <app> --tail 20 --no-follow. The command ends when the device closes the stream after its replay (agents with finite log replay), when it switches from replayed to live output, or after a short pause once the replay stops (1.5 s, stretched on a slow link up to 10 s; the command notes on stderr when it ended this way with fewer batches than --tail, or than the 20 the device caches without it). Device agents released before 2026-08-19 replay history only with --tail, and those before 2026-05-22 not at all; when nothing is replayed, the command says so on stderr and exits. |
wendy device info
Shows organization, agent version, OS, architecture, GPU, NPU, and hardware info for the target device.
Os Logs
wendy device os-logs streams the device's kernel ring buffer (dmesg) for inspecting kernel/boot/hardware messages. By default it replays the buffered records and then keeps followi
