# Command: alloc-status
|
|
|
|
The `alloc-status` command displays status information and metadata about an
|
|
existing allocation and its tasks. It can be useful while debugging to reveal
|
|
the underlying reasons for scheduling decisions or failures, as well as the
|
|
current state of its tasks.
|
|
|
|
## Usage
|
|
|
|
```
|
|
nomad alloc-status [options] <allocation>
|
|
```
|
|
|
|
An allocation ID or prefix must be provided. If there is an exact match, the
|
|
full details of the allocation will be displayed. Otherwise, a list of matching
|
|
allocations and information will be displayed.
|
|
|
|
