# ListMeters

The `ListMeters` action returns information about statistics meters, including the meter name, the meter type, and whether the meter is enabled. It shows both enabled and disabled meters.

By default, `ListMeters` returns all meters for all the connected services. You can use Port and Type to restrict the response to a specific service or type of meters.

`ListMeters` does not include any statistical values for the meters. To retrieve this information, use the GetStatistics action.

## Example

    a=ListMeters

    a=ListMeters&Port=9000&Type=process

## Optional Parameters

This action accepts the following optional parameters.

Parameter | Description
--- | ---
Port | The port on which the service for which you want to return the list of meters is running.
Type | The type of meter to return.

## Comments

You can also send `ListMeters` from Coordinator, which retrieves the meters from the connected Controller components. For more information, refer to the Coordinator Reference.
