Metering Gateway Installation and Configuration

The MGT application is a metering gateway that accepts metering data from grids within a customer's datacenter and forwards that data to CA's metering system. In addition, MGT provides an interface through which the customer may manage the SSL certificate MGT uses to communicate with CA's metering system.

Initial Application Setup

To install and configure the MGT application, perform the following:

Download the application and copy it to the CA 3Tera AppLogic distro (that is, /root/applogic-3.0)
From the CA 3Tera AppLogic distro, import the application to the grid:
```
./aldo ai grid=<grid name> applications=MGT
```
Login to your grid and resize the data volume. The size of the data volume should be sufficient to store at least 30 days of metering data for all grids that report to this instance of MGT (approximately 4 MB per grid for 30 days of metering data). For example, to resize the data volume to 3 GB, execute:
```
vol resize MGT:data size=3G
```
Configure the application. To retrieve the set of parameters that may be configured, see the MGT reference or execute:
```
app config MGT --boundary
```
Start the application. Execute:
```
app start MGT
```
Setup the client-side SSL certificate.

Note: The grid on which the MGT application is running must have access to the internet because MGT communicates with CA's metering server.
