STV Import: Java Heap Monitor
 

Running out of Java Heap space can cause many issues when running SageTV. You can go to the System information menu to see how big your Java heap is and how much memory is available, but how often do you really look there?

This STVi gives you the option to display a small bar style graph in the upper right portion of the Main Header that displays how much Java heap space is available. It also allows you to have System Messages generated if the amount of used Java heap memory exceeds user defined thresholds.

To install: Unzip to your SageTV install directory (usually C:/Program Files/SageTV/SageTV) and import the JHM stvi. There is no need to shutdown Sage.

Once installed you can configure the options by going to Setup->Detailed Setup->Customize menu. At the end of the list you will find the Java Heap Monitor.

Explanation of options:

• Enable or Disable - Does what it says. Disable turns off all functionality.
• Current Values - Displays the current heap status in the same format as is used in the System Information menu (Used/Total/Max).
• Show Meter in Main Header - Control if the graphical meter is displayed or not.
• Meter Update Interval - Controls how often the meter in the Main Header is updated. The value is specified in milliseconds. You can set it as low as 500ms but I recommend you leave it at 1000ms or higher.
• Use System Messages - Controls if system messages will be generated if the size of the Java heap exceeds the threshold levels.
• Warning Threshold - If the size of the Java heap exceeds this level a warning level (yellow) system message will be generated. A message will be generated once every hour if the heap size does not go below the threshold.
• Error Threshold - If the size of the Java heap exceeds this level an error level (red) system message will be generated. A message will be generated once every hour if the heap size does not go below the threshold.

Note that the meter related options can be set for each client/extender/placeshifter. The system message related options are server based.

Version 1.11 available for Sage7.

Version 1.20 is now available:

• Use new STV hook provided to avoid collisions with other STVi's that need to put icons in the header.
• Changed default setting so the meter is enabled by default.
