System Monitor for CPU / Memory

This extension displays system's cpu or memory usage on the extension icon. Mouse over on it to show more details. You can set options in the popup page: • Display Type: CPU or Memory • Display Format: Number or Graph • Update Frequency • Enable or Disable Note: 1. Memory Usage: because system cache is also counted as used memory, high memory usage does not necessarily mean insufficient memory. 2. CPU Temperature: it is displayed in the tooltip of the extension icon when you select "Display Type: CPU", and it is only available on Chrome OS.
