# ListMeters

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

By default, `ListMeters` returns all meters for all the connected Controllers, and all services. You can use ControllerUUIDs, Port, and Type to restrict the response.

Coordinator attempts to retrieve the latest live values for meter names from the Controllers. If a Controller is unavailable, Coordinator uses the cached values, and returns a warning that the values are cached. You can also explicitly request the cached values by setting `LiveDetails` to `False`. In this case, Coordinator does not return a warning.

`ListMeters` does not return 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
--- | ---
ControllerUUIDs | The UUIDs of the Controllers for which you want to return the list of meters.
LiveDetails | Whether to retrieve the latest meters from connected Controllers, or to use the cached versions.
Port | The port on which the service for which you want to return the list of meters is running.
