System status
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), "Fail" shows. If a response is received, "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 five second period, "Success" shows. If it gets none, "Fail" shows. If it receives less than the expected number, "Slow" shows.
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, "Fail" shows. If a response is received, "Success" shows.
Browser compatibility
The GUI will run the same browser tests that it does at startup. It will check for certain versions of IE and the protocol used. Here are some of the messages that may show:
- This version of IE is not supported
- WEBGL is not supported by this browser
- Protocol is not secure (https)
- Not supported
- Supported, but zoom level is not 100%
If any of these states is detected, an "i" icon shows. When the icon is clicked, the Recommended browsers help topic shows.
If none of these states is detected, "Supported" shows. No help icon shows in this case.
Push server
This shows the results of an attempt to communicate with the push server. If successful, "Success" shows. If not, "Fail" shows. This does not require any push notifications to have been created/configured. See Notifications for configuring a push notification.
