# 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.
## General Options
<%= general_options_usage %>
## Alloc Status Options
* `-short`: Display short output. Shows only the most recent task event.
* `-verbose`: Show full information.
## Examples
Short status of an alloc:
```
$ nomad alloc-status --short 13901f26
ID = 13901f26
Eval ID = c3c9a1db
Name = example.cache[0]
Node ID = 1f029d38
Job ID = example
Client Status = running
==> Tasks
Name State Last Event Time
redis running Started 29/03/16 03:04:53 UTC
web running Started 29/03/16 03:04:53 UTC
```
Full status of an alloc, which shows one of the tasks dying and then being restarted:
```
$ nomad alloc-status a7365fe4
ID = a7365fe4
Eval ID = c3c9a1db
Name = example.cache[0]
Node ID = 1f029d38
Job ID = example
