2.3 Monitoring

Depending on whether or not you have subscribed to application and/or server monitoring, the Monitoring interface allows you to view statistics and graphs about applications and servers within your Corente network.

  • Server monitoring allows local administrators to monitor local servers. Simply register the server(s) with the local Corente Virtual Services Gateway in App Net Manager, and you can view usage statistics about each server concerning CPU, disk space, physical memory, and/or swap space.

  • Application monitoring allows your company to deploy applications easily between sites within your Corente network. Simply register the application with the local Corente Virtual Services Gateway in App Net Manager, and you can share the application securely (like an User Group) with any other Corente location(s) within your intranet or extranet. Corente application monitoring was designed with the following principles in mind: to confirm to both users and administrators that the applications are functioning correctly; to facilitate communication between both parties when they are not; to provide reports to help with capacity planning; and to provide diagnostic capabilities to locate bad actors within the network.

  • Top Talkers allows you to monitornetwork activity between machines on the local network and machines at remote sites and/or the Internet, to identify what machine pairs are using up the most bandwidth (i.e., the "top talkers").

The features that are available on the Monitoring screen(s) depend on whether or not you have logged in to Gateway Viewer via the Admin Login.

2.3.1 User Interface

The User Interface of Monitoring will be displayed if you have subscribed to application monitoring and if you have not logged into Gateway Viewer via the Admin Login button. This is the default page of the Gateway Viewer application.
