The state of system communications can be seen on this page.
Ping server
This does a simple "ping" to the server connected. If no response is received within a reasonable period of time (2 seconds), it will display a "Fail" status. If there is a response, "Success" shows.
Comet stream
This will monitor events coming from the comet stream. In particular, it looks at the "live_data" events. If it gets the expected number of events over a 5 second period, it will display "Success". If it gets none, it will display "Fail". If it does receive some but is less than the expected number, it will display "Slow".
API test
A simple API will be consumed to see if the api_server is responding. This api simply gets the system firmware version. If no response is ever received in relation to this api call, it will return "Fail" else "Success".
Browser compatibility
The GUI will just run the same browser tests it does at startup. It will check for certain versions of IE and the protocol used. Here are some of the messages that may display:
If any of these states is detected, an "i" help icon shows. When the icon is clicked, the Recommended browser help topic shows.
If none of these states is detected, it will display "Supported". No help icon is displayed.
See Recommended browsers for information about browsers which effectively support this system.
Push server
This shows the result of attempt to communicate with the push server. If communication occurs, "Success" shows, if not, "Fail" shows. This does not require any push notifications to have been created/configured. See Notifications for information about configuring push notifications.
Click the Refresh button to verify system communications are successful.
If results to Refresh do not show as Successful, a related issue is antivirus software running on the client device. Using HTTPS will minimize the likelihood of antivirus software negatively impacting display capabilities. For users who are not connected to the Internet, disabling antivirus software should be considered.
If Refresh persistently shows no Successful results for an option, see Customer support for guidance.
