The ECS Streamer driver publishes debug information that is not typically viewable. With the Microsoft DebugView utility, administrators can view and log debug information that all applications write.

Download DebugView from https://docs.microsoft.com/en-us/sysinternals/downloads/debugview.

Run DebugView as administrator.

Figure 14.    Running DebugView

When running DebugView, ensure that Capture Win32 and Capture Global Win32 are selected.

Figure 15.    DebugView settings

If you repeat a partition properties test specifying ;LB=true, the DebugView window will show the following output:

00140407 10:34:52 AM [9392] IP list coming in Init...prior to any possible client side load balancing

00140408 10:34:52 AM [9392] 10.246.22.187

Enable more debugging output by running the Enterprise Vault dtrace.exe utility from the Enterprise Vault product installation directory and running the following command:

set StorageManagement v y

Figure 16.    Running Enterprise Vault DTrace

If you repeat the same test on the ECS partition, you will get a more detailed debug output.
