All products must use the same OAS server.

The fully qualified domain name (FQDN) all products use has a common "cookie domain."

The users' web browsers need to send the OAS cookies, which affects the choice of common "cookie domain."

All possible FQDNs must be registered within OAS to allow them to work.

Install agents on a limited number of machines.

Restart the server.

Agents self tune so there is no need to control the overhead.

Never install more than 5 agents.

Use multiple consoles.

Unplug the server.

You can toggle back and forth between the source code and the AppInternals Xpert performance data to examine selected class/method transactions that exceed a particular duration.

You can open the source code directly into Transaction Trace Warehouse.

In Visual Studio or Eclipse source code, you can click on the name of a generic method or click inside the code for the method and link to traces on transactions that the .NET or Java code generated, and display those transactions in Transaction Trace Warehouse.

You can click on the name of a generic method or click inside the code for the method and link to AppInternals Xpert metrics that the method generated, displaying in the desktop console.

You can open the source code directly into Transaction Trace Analysis.

Historical comparison row

The threshold values came from the data source, AppInternals Xpert.

The absolute worst response time in the dashboard's time range was 1.5 minutes.

The gauge is actually showing the minimum maximum value.

The gauge's value is the average of the maximum servlet response times for the dashboard's time interval.
