Tracing

ESMAC provides access to several Enterprise Server Cluster tracing facilities.

Configuring an Enterprise Server Cluster for Tracing

To configure an Enterprise Server Cluster region for tracing, go to the ESMAC home page, and note the name of your SIT - it is listed in the Startup section slightly below the middle of the main panel. Then click on SIT in the Resources group in the left-hand column, and on the next screen, click the Details button to the left of where the name of your SIT appears.

On the following screen, check the cluster trace box in the Trace Points pane:

Alternatively, from the main ESMAC page, you can enable cluster traces dynamically by clicking on the Control button towards the top of the left-hand column and checking the cluster trace box in the Trace Points pane:
