Implement a new subcommand: tendermint debug. This subcommand itself has two subcommands:

1. $ tendermint debug kill <pid> </path/to/out.zip> --home=</path/to/app.d>

Writes 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

The Tendermint process will be killed.

2. $ tendermint debug dump </path/to/out> --home=</path/to/app.d>

This command will perform similar 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.
