- # Debugging
-
- ## tendermint debug kill
-
- Tendermint comes with a `debug` sub-command that allows you to kill a live
- Tendermint process while collecting useful information in a compressed archive.
- The information includes the configuration used, consensus state, network
- state, the node' status, the WAL, and even the stack trace of the process
- before exit. These files can be useful to examine when debugging a faulty
- Tendermint process.
-
- ```bash
- tendermint debug kill <pid> </path/to/out.zip> --home=</path/to/app.d>
- ```
-
- will write debug info into a compressed archive. The archive will contain the
- following:
-
- ```
- ├── config.toml
- ├── consensus_state.json
- ├── net_info.json
- ├── stacktrace.out
- ├── status.json
- └── wal
- ```
-
- Under the hood, `debug kill` fetches info from `/status`, `/net_info`, and
- `/dump_consensus_state` HTTP endpoints, and kills the process with `-6`, which
- catches the go-routine dump.
-
- ## tendermint debug dump
-
- Also, the `debug dump` sub-command allows you to dump debugging data into
- compressed archives at a regular interval. These archives contain the goroutine
- and heap profiles in addition to the consensus state, network info, node
- status, and even the WAL.
-
- ```bash
- tendermint debug dump </path/to/out> --home=</path/to/app.d>
- ```
-
- will perform similarly to `kill` except it only polls the node and
- dumps debugging data every frequency seconds to a compressed archive under a
- given destination directory. Each archive will contain:
-
- ```
- ├── consensus_state.json
- ├── goroutine.out
- ├── heap.out
- ├── net_info.json
- ├── status.json
- └── wal
- ```
-
- Note: goroutine.out and heap.out will only be written if a profile address is
- provided and is operational. This command is blocking and will log any error.
