## `Monitor_check` Method

The RGM runs the `Monitor_check` callback method on a resource on a node for the specified resource to ascertain whether the cluster node is capable of mastering the resource. In other words, the RGM runs this method to determine whether the application that is being managed by the resource can run successfully on the node.

Typically, this situation involves ensuring that all the system resources that are required by the application are indeed available on the cluster node. As discussed in `Validate` Method, the function `svc_validate()` that you implement is intended to ascertain at least that.

Depending on the specific application that is being managed by the resource type implementation, the `Monitor_check` method can be written to carry out additional tasks. The `Monitor_check` method must be implemented so that it does not conflict with other methods that are running concurrently. If you are using the DSDL, the `Monitor_check` method should call the `svc_validate()` function, which implements application-specific validation of resource properties.
