# RunScript

Controller uses Lua scripts to monitor the services it controls. You can use the `RunScript` action to run a Lua script to test system changes on an on-demand basis.

The `RunScript` action returns the same information as the GetStatusOverview action.

## Example

    a=RunScript&ScriptName=/scripts/luaScripts/checkstatus.lua&Port=9000

## Required Parameters

The following action parameters are required.

Parameter | Description
--- | ---
ScriptName | The name of the script to run.

## Optional Parameters

This action accepts the following optional parameters.

Parameter | Description
--- | ---
Labels | The labels of the services on which to run the script.
Port | The port on which to run the script.
Type | The type of script to run.
Types | The service types on which to run the script.

## Comments

You can also send the `RunScript` action from Coordinator by specifying a comma-separated list of Controller UUIDs on which to run the script (if unspecified, it runs it on all Controller servers).

For example:

    a=RunScript&ScriptName=/scripts/luaScripts/checkstatus.lua&controllerUUUIDS=d267cf80-063a-8030-a2de-24be0523821c,4e572f80-460c-8030-a2de-005056bd31f6

This action returns information for the Controller servers with the specified UUIDs. For more information, refer to the Coordinator Reference.
