During the planning of your digital signage network assessing maintenance and monitoring is paramount. To improve remote media player health monitoring, I wrote an application that takes a current screen grab, collates health information such as CPU temperature, system status, free hard drive space, critical errors and uploads this vital information to a central FTP or web server.
Once this information has been uploaded it can be used to form part of an administrative web site to monitor the health and status of a digital signage network in real time. If there is an issue to resolve, it is good practice to install remote access software to gain control of the media player as if you were standing infront of it.
Below is a screen shot of a web site I wrote which displays the vital digital signage network information on a single web page that automatically refreshes with the latest information every 5 minutes. If there is a potential problem with a media player, the monitoring staff will know about it before the client does! It is also an effective way of ensuring the correct screen content is playing and the digital signage software is running correctly.
