Abstract: Connection activity between a device and service provider's network is monitored. Connection parameters calculated based on the connection activity are stored. An activity map is generated to capture and display the connection parameters which indicate activity or repeated patterns of activity over time. The activity utilizes a time grid to display a plurality of parameter regarding device status and activity. The x-axis of the time grid divides a time period into portions of time at a first time length. The y-axis of the time grid divides the portions of time at the first time length into smaller lengths of time at a second time length. Multiple layers of indicators are used in the time grid to indicate the status of several parameters during the same time period.
