Launching the Alerts User Interface

The Alerts user interface is bundled with HCP but you need to copy the metron-alerts tar file to the desired host before you can launch the UI.

Prerequisite:

In order to view alerts in the Metron Alerts UI you must first generate alerts from the Metron topologies.

Download a copy of the HCP code from https://github.com/apache/metron.
```
git clone https://github.com/apache/metron.git
```
Perform a fresh build of Metron to retrieve the Alerts tar file:
```
cd <ROOT FOLDER of CODE>
mvn clean package -DskipTests
```
Copy metron/metron-interface/metron-alerts/target/metron-alerts-METRON_VERSION-archive.tar.gz to the Metron host.

Untar the archive in the $METRON_HOME directory. The directory structure will look like:

 ```
    bin
       start_alerts_ui.sh
    web
       alerts-ui
         package.json
         server.js
         web assets (html, css, js, ...)
    ```

Start the application with the following script:

./bin/start_alerts_ui.sh
        Usage: server.js -p [port] -r [restUrl]
        Options:
          -p  Port to run metron alerts ui [required]
          -r, --resturl  Url where elastic search rest api is available  [required]

Launch the Alerts UI using a web browser:
```
http://<metron_server>:3000/alerts-list
```

	Note
	There is no login module for the Alerts UI.
