// Updates a monitor. You can update a monitor to change the maximum number of
// city-networks (locations and ASNs or internet service providers), to add or
// remove resources, or to change the status of the monitor. Note that you can't
// change the name of a monitor. The city-network maximum that you choose is the
// limit, but you only pay for the number of city-networks that are actually
// monitored. For more information, see Choosing a city-network maximum value (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/IMCityNetworksMaximum.html)
