# Command: debug
|
||
|
|
|
||
|
|
The `debug` command builds an archive containing Nomad cluster
|
||
|
|
configuration and state information, Nomad server and client node
|
||
|
|
logs, and pprof profiles from the selected servers and client nodes.
|
||
|
|
|
||
|
|
If no selection option is specified, the debug archive contains only
|
||
|
|
cluster meta information.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```plaintext
|
||
|
|
nomad debug [options]
|
||
|
|
```
|
||
|
|
|
||
|
|
This command accepts comma separated `server-id` and `node-id` IDs for
|
||
|
|
monitoring and pprof profiling. If IDs are provided, the command will
|
||
|
|
monitor logs for the `duration`, saving a snapshot of Nomad state
|
||
|
|
every `interval`. Captured logs and configurations are subjected to
|
||
|
|
redaction, but may still contain sensitive information and the archive
|
||
|
|
contents should be reviewed before sharing.
|
||
|
|
|
||
|
|
If an `output` path is provided, `debug` will create a timestamped
|
||
|
|
directory in that path instead of an archive. By default, the command
|
||
|
|
creates a compressed tar archive in the current directory.
|
||
|
|
|
||
|
|
Consul and Vault status and version information are included if
|
||
|
|
configured.
|
||
|
|
|
||
|

|
pprof data.
|
||
|
|
