Class Loading

The Class Loading page shows a graph of samples currently stored in memory by FusionReactor. Class loading shows the number of classes being loaded and unloaded.

Why would I want to see Class Loading?

This graphs aids can help find performance issues caused by excessive time spent loading classes.  This may further point to issues where dynamically-created classes are being manipulated excessively.

Class Loading Graph

Several time spans are available, with differing resolutions. These will be filled as data points that are collected by FusionReactor.

Each time varying graphs shows two independent values overlaid: 

Classes Loaded - Count: Blue

  • This shows the number of classes loaded since the last sample.

Classes Unloaded - Count: Green

  • This shows the number of classes unloaded since the last sample.

You're able to deselect and reselect each independent values by simply clicking on their respective names. When a value is deselected (greyed out) then that value will no longer be displayed on the activity graph.

Placing your mouse pointer on a data point within the graph displays a tool-tip with details about that sample, including:

  • Date and time of the request
  • Classes Loaded - Count
  • Classes Unloaded - Count 

When browsing the 1 Hour, 1 Day, and 1 Week activity graphs you're able to select time frames by using the slider under the graph.
