How to Create Devices and Targets
Identify the Media You Are Trying to Monitor
This is frequently confused with the web page or media player location on your website. The target of a streaming media task will not be the URL of a player or webpage that contains the player, but the actual media resource path that is used by a player to play the file.
Once you have identified the location, check the media file type. What protocol does it use? (make sure to specify the protocol in the file path (such as rtmp:// or https://, for example).
Depending on the file type and codec, the task will play the media file back in one of several engines that generate slightly different monitoring values: a general player, or Windows Media Player.
The task execution involves the following steps:
- The system hits the stream URL and connects the stream server.
- In the case of the playlist, the system gets the list of the stream URLs.
- The stream properties such as codec, quality, etc. are requested from the server.
- The system downloads the first 30 sec of the stream to decode.
- If the source server is unavailable or the system failed to download the 30 sec of stream playback, the error will be generated.
Creating a Target
Enter the address of the actual media source you wish to monitor. Note that the URL must link directly to the media file and not a web page that contains a media player. For example, “http://streammedia.com/stream.asf”.
Time Validation Threshold (in seconds)
Enter the number of seconds the task should wait for a response from the web page before ending the task and returning an error. If this is left blank the default timeout for a task is 120 seconds.
Apart from the media URL, you can choose MediaEngine and ReportDetails by adding to the Prepare Script field:
(Tasks as Media).MediaEngine= “GENERAL”;
(Tasks as Media).ReportDetails = “FULL”;
Tasks[<sequential number of the task>] – specifies the sequential number of the task in the device. Note that the numbering of tasks in the device starts from 0. So to refer to the first task in the device you should provide Tasks.
MediaEngine = ( “GENERAL”, “WMP”)
ReportDetails = (“STANDART”, “FULL”, “SHORT”)
You can set a filter to ignore specific error types and codes. For example, DNS errors could be filtered out based on who is responsible for DNS server operations. You can create filters that will ignore specific errors that you know may occur and are not relevant to the goal of a specific device.
In addition, you can set up the system to ignore a range of error codes using a dash, or multiple error codes using semicolons as a separator.
