# RabbitMQ Top Plugin
Adds UNIX top-like information on the Erlang VM to the [management UI](https://www.rabbitmq.com/management.html).
The closest interactive CLI alternative in recent releases is `rabbitmq-diagnostics observer`.
This is what it looks like:
## Installation
This plugin ships with RabbitMQ as of `3.6.3`. Enable it with
``` bash
# use sudo as necessary
rabbitmq-plugins enable rabbitmq_top
```
### RabbitMQ 3.5.x
You can download a pre-built binary of this plugin for RabbitMQ `3.5.x` from [RabbitMQ Community plugins page](https://bintray.com/rabbitmq/community-plugins/rabbitmq_top).
## Usage
Sort by process ID, memory use or reductions/sec (an approximate
measure of CPU use).
Click on the process description (e.g. "my queue") to see that
object's management view.
Click on the process ID (e.g. "<0.3423.0>") to see some more
Erlang process details.
See [Memory Use Analysis guide](https://www.rabbitmq.com/memory-use.html) on RabbitMQ website
for more information.
## HTTP API
You can drive the HTTP API yourself. It installs into the management plugin's API; you should understand that first. Once you do, the additional paths look like:
/api/top/<node-name>
List of processes. Takes similar query string parameters to other
lists, `sort`, `sort_reverse` and `columns`. Sorting is quite
important as it currently hard-codes returning the top 20 processes.
/api/process/<pid>
Individual process details.
## More Screenshots
Individual process metrics are also available:
## Building from Source
You can build and install it like any other plugin (see
[the plugin development guide](https://www.rabbitmq.com/plugin-development.html)).
