Monitor Memory Usage by Host

To monitor memory usage by host:

1. Click the Memory tab in the left pane.

   The second chart (Memory Usage by Host) lets you compare the memory usage between different app server instances. Each instance is represented by a cell. The size of each cell is determined by the host memory usage, while the color of each cell is determined by the percentage change in the host memory usage. Shades of red indicate a growth in memory usage while shades of green indicate that the memory usage has shrunk. Grey cells indicate no change in memory usage.

2. Click the Group By list to select the metrics to group the app server instances.

3. Select the app server instances for which you want to view specific information by clicking the corresponding cell. If you’ve decided to group the app server instances, then you can select a group of instances by clicking a specific block.
   Data about the current trend of heap usage and the forecasted memory usage for the selected app server instances loads in the Trend and Forecast chart.
