Monitoring allows you to view statistics and graphs about applications and servers within your application network, as well as data about bandwidth usage by individual machines.
Application
Application monitoring allows your company to deploy applications easily between sites within your application network. Simply register the application with the local Corente Services Gateway in App Net Manager, and you can share the application securely (like a User Group) with any other Corente Services Gateway within your intranet or extranet. 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.
Server monitoring allows local administrators to monitor local servers. Simply register the server(s) with the local Corente 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.
Top Talkers allows an administrator to monitor network 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.
The User Interface of Monitoring will be displayed if you have not logged into Gateway Viewer via the Admin Login button. This interface allows users to view the status of each application that is available on local and remote networks, and to communicate with the specific administrator of each application via email. This interface will be available only if you have been permitted access to an application from a network that has subscribed to the application monitoring service. Depending on the permissions that the user's IP address has been granted via tubes in App Net Manager, this page may not be available or applications that appear on this page may not be accessible. If unsure, users should contact their administrators to determine what applications they have been permitted to access. The tables on this interface can be sorted via any category simply by selecting that category's heading. The category that is currently used for sorting will be displayed in bold characters. By default, the tables will be sorted alphabetically by the Application category. The information on this interface will refresh automatically every 1 minute. You can manually refresh the interface at any time by right-clicking your mouse and selecting Refresh from the menu that appears.
The Application Status Summary table displays information about applications that you can access on local or remote networks via your company's secure application network:
- Application

The Administrator Interface of Monitoring will be displayed if you have logged into Gateway Viewer via the Admin Login button and subscribed to the application monitoring and/or server monitoring service. This interface provides network administrators with tools for analysis and problem drill down concerning the network as well as the applications and servers running on the network. It is more complex than the user interface and contains multiple screens:
You can set the refresh rate for the Administrator Interface of Monitoring by clicking the refresh icon that is displayed at the top of each page. Enter a value in the dialog box that appears. You can enter a value between 0 seconds and 3600 seconds (1 hour). This value is persistent and will be used for all Monitoring pages. The default refresh rate is 60 seconds (1 minute). A refresh rate of 0 seconds means that you do not want the page to automatically refresh. To manually refresh a page at any time, click the right mouse button within the frame that you would like to refresh and select the Refresh option from the menu that appears.
In general, do not use the Back button on your browser to navigate through the monitoring interface. This may cause cached information to be displayed. To ensure that you are viewing the most up-to-date data, use only the hyperlinks provided on the interface to load pages.
The Application Status on Network page provides a summary of the local applications, network links, and servers that are registered on the local Corente Services Gateway for monitoring and/or sharing with other application network locations.

The Top Talkers page will be available from the Monitoring menu if you have logged into Gateway Viewer via the Admin Login button.
Top Talkers allows an administrator to monitor network 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"). This feature is useful, for example, as a way of identifying machines infected by a Trojan horse or local users abusing BitTorrent.
When an administrator selects Top Talkers, the page will be opened using the default configuration settings. Top Talkers will begin after a 10 second delay, during which time it is gathering information. The Top Talkers page will then be updated automatically based on the refresh rate that you choose for the Monitoring pages. (The maximum refresh rate allowed for Top Talkers is 60 seconds. If a refresh rate longer than 60 seconds has been chosen for the Monitoring pages, the refresh rate will be temporarily changed while the Top Talkers page is open to refresh every 60 seconds. Similarly, the minimum refresh rate allowed is 10 seconds. If a refresh rate shorter than 10 seconds has been chosen, the refresh rate will be temporarily changed to 10 seconds while the Top Talkers page is open.) Each refresh presents new, non-aggregated data.
Only one administrator can monitor the Top Talkers page for a Corente Services Gateway at a time. If another administrator of the Corente Services Gateway attempts to open the Top Talkers page, an error message will be displayed to inform the administrator that someone else is already using it.
The page presents the following data in a table:
- Local Host
The WINS name (if applicable) of the local machine in the top talker pair.
- Local IP
The IP address of the local machine in the top talker pair.
- Port
The port number being communicated with on the local machine in the top talker pair (when Display Type is By Address and Port; see Set Options).
- Remote IP
The IP address of the remote machine to which the Local Host is "talking".
- Remote Port
The port number being communicated with on the remote machine (when Display Type is By Address and Port; see Set Options).
- Bytes Sent
The number of bytes sent by the local top talker to the remote machine.
- Bytes Received
The number of packets or bytes received by the local top talker from the remote machine.
- Bytes Total
The aggregate number of packets or bytes both sent and received by the local top talker to/from the remote machine.
An administrator can click Set Options to view or change the monitor and display options. Any new selections will apply to all subsequent reports until the options are changed again or you navigate to another page.
Only the traffic that travels through the Corente Services Gateway will be measured by Top Talkers. This means that if your Corente Services Gateway is in the Peer configuration, only secure Corente Services network traffic and traffic that is specifically routed through the gateway will be included in the calculations.
When you select Set Options, you can change how the Top Talkers page reports and displays data. You can change the options on this page as follows:
- Interface
Select the network interface of the Corente Services Gateway that will be monitored for discovering top talkers. By default, the LAN-side interface of the gateway will be used.
- Address Range
Enter an address pool of local IP addresses that will be included in calculating the top talkers. By default, this field will be filled in with the address range defined for that interface.
- Display Type
Choose the way in which is data is examined and displayed. By default, By Address and Port will be selected. Bandwidth use will be examined in port number to port number pairs between each pair of local and remote machines. This can be helpful for administrators, if they are trying to narrow down the specific bandwidth stealing culprits on the machine pairs (i.e., web traffic, a specific application, etc.). Selecting By Address Only will change Top Talkers monitoring so that top talkers will be determined by the total traffic between machine pairs.
- Duration
Enter the amount of time (in seconds) for monitoring. By default, the duration is set to 10 seconds.
- Report Count
Enter the number of top talkers to display. By default, the top 10 talkers will be displayed. The maximum number of top talkers that can be displayed is 50.
When you select Submit to save your changes, the new options will apply to all subsequent Top Talkers refreshes (until the options are changed again). If you navigate to another page, all options you have changed will return to the default values.
