Real time gauges are useful when you have to monitor the current value without considering historical values. The article Setting up Real Time Gauges describes how gauges can be set to update in real time.
Here are a few problems that might come up with real time gauges, and the possible solutions:
Problem 1: Gauge does not update in real time
If the real-time gauge is set up to receive data from the server and the gauge renders initially but does not update subsequently, ensure that:
you have specified a valid path for the
if the URL has special characters like
&, then URL-encode the
dataStreamURLattribute returns correct data. To test this, run the URL on a separate page on your browser and it should return data in text format. Ensure the data returned does not contain carriage return (new-line characters) or HTML elements
you have specified a valid value for the
the page that provides incremental data update to the gauges is hosted on the same sub-domain. For instance, a chart residing at “server1.mydomain.com” will not be able to access data from “mydomain.com”.
To load data from a different domain, setup a proxy page at the sub-domain. The page will request data from the distant domain and relay it to the gauge.
