Media stream monitor with heartbeat timer
A stream monitor can request a streaming media server to send stream records associated with streams currently being served. The stream monitor uses the stream records to test streams being served by the streaming media server. The stream monitor can concurrently test multiple streams for connection errors, silence errors, metadata errors, and other errors. The stream monitor initiates a data stream monitoring application, initiates a heartbeat timer to produce a periodic heartbeat signal and delivers, to a host webpage, a last data stream record to be tested in conjunction with the heartbeat signal. When a periodic heartbeat signal is not received in a timely manner the monitor restarts the stream testing application at the last data record tested.
1. A method for data stream monitoring, the method comprises:
initiating a data stream monitoring application;
initiating a heartbeat timer to produce a periodic heartbeat signal;
delivering, to a host webpage, a last data stream record to be tested in conjunction with the periodic heartbeat signal;
detecting that the periodic heartbeat signal was not received with the last data stream record; and
restarting, based on the detecting, the data stream monitoring application at the last data record tested.
2. The method of claim 1 , wherein the initiating a heartbeat timer to produce a periodic heartbeat signal triggers delivering of the periodic heartbeat signal to an application host container of the data stream monitoring application.
3. The method of claim 2 , wherein the delivering of the periodic heartbeat signal to the application host container indicates that flash virtual memory (VM) is still running.
4. The method of claim 1 wherein the delivering, to a host webpage, a last data stream record to be tested in conjunction with the periodic heartbeat signal includes delivering a JavaScript message to the host webpage.
5. The method of claim 1 further comprises creating a test stream metadata controller instance includes adding listeners for a controller's clear text, error, or info events.
6. The method of claim 1 , further comprises dispatching a data ready event, indicating that it is ready to display data.
7. The method of claim 1 wherein the heartbeat timer is a ping-timer.
8. The method of claim 1 further comprises listening for a stream event once for every stream record received.
9. A stream monitoring method, the method comprises:
a host web page initializing a stream monitoring application;
accepting a last data stream record and a total number of streams to retrieve for testing at one time;
loading and rendering testing components;
storing a last record parameter passed to the stream monitoring application;
initializing a heartbeat timer;
adding listeners for a timer event;
starting the heartbeat timer to send periodic heartbeat signals on a selected periodic basis;
sending the last data stream record with the heartbeat timer to the hosting web page;
when not receiving the heartbeat timer, recognizing an application failure; and
restarting the stream monitoring application by the host web page.
10. The stream monitoring method of claim 9 , wherein the initializing a heartbeat timer to produce a periodic heartbeat signal triggers delivering of the periodic heartbeat signal to an application host container of the stream monitoring application.
11. The stream monitoring method of claim 10 , wherein the delivering of the periodic heartbeat signal to the application host container indicates that flash virtual memory (VM) is still running.
12. The stream monitoring method of claim 9 further comprises creating a test stream metadata controller instance.
13. The stream monitoring method of claim 9 , wherein the adding listeners includes adding for a controller: clear text event, error event, or information events.
14. The stream monitoring method of claim 9 , further comprises dispatching a data ready event, indicating that it is ready to display data.
15. The stream monitoring method of claim 9 , wherein the heartbeat timer is a ping-timer.
16. The stream monitoring method of claim 9 further comprises listening for a stream event once for every stream record received.
17. A stream monitoring method, the method comprises:
initializing, by a host web page, a stream monitoring application;
accepting a last data stream record and a total number of streams to retrieve for testing at one time;
loading and rendering testing components;
triggering an instantiation of a test stream metadata view;
passing the stream monitoring application as a parameter;
creating a test stream metadata controller instance to store a reference of the test stream metadata view;
registering base view event data ready as an event handler;
initializing a heartbeat timer;
adding listeners for a timer event;
starting the heartbeat timer to send periodic heartbeat signals on a selected periodic basis;
sending the last stream record with the heartbeat timer to the hosting web page;
when not receiving the heartbeat timer, recognizing an application failure; and
restarting the stream monitoring application by the host web page.
18. The stream monitoring method of claim 17 , wherein the initializing a heartbeat timer to produce a periodic heartbeat signal triggers delivering of the periodic heartbeat signal to an application host container of the stream monitoring application.
19. The stream monitoring method of claim 18 , wherein the delivering of the periodic heartbeat signal to the application host container indicates that flash virtual memory (VM) is still running.
20. The stream monitoring method of claim 17 further comprises listening for a stream event once for every stream record received.
