Connect to the Postgres configuration database and view the definition for the appropriate dashboard view.

In Manage Resources, select the dashboard and click the Details button.

In the Open Saved Dashboard dialog panel, right-click on the dashboard name and select Preview.

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.

This transaction takes about 4 seconds to complete and this analysis proves the user's belief that additional WAN bandwidth would improve application performance.

The majority of activity is between the two servers.

Most of the traffic consists of small messages.

Much of the application response time is caused by the Wide Area Network (WAN).

An error message is displayed and the license manager window opens.

AppTransaction Xpert starts as normal, but issues a warning that another license should be purchased.

AppTransaction Xpert doesn't start and does not throw an error message.

The failure to start causes your laptop to shutdown.

Use the built-in email and SNMP mechanism or a custom forensic script in AppInternals Xpert to send alerts to the existing system.

Configure alerts in AppResponse Xpert to send SNMP traps to the existing system.

Set up BrowserMetrix to send email alerts to an email gateway.

Add email alerts to the RPM Dashboard settings.

Configure Transaction Trace Warehouse to send email alerts to an email gateway when certain thresholds are met.

Both provide average data, but AppInternals Xpert has data at 1-second granularity while AppResponse Xpert has data at 1-minute granularity.

Measuring common requests, AppResponse Xpert data provides network and server processing delay while AppInternals Xpert provides server processing delay only.

Assuming response time is being evaluated for a common request available from both data sources, AppInternals Xpert data is the maximum response during each 1-second bucket while AppResponse Xpert data is averaged over a 1-minute bucket.

AppInternals Xpert "Max. Active" metrics on Servlet/JSP/Web Aggregate metrics should exactly match AppResponse Xpert "Connections" metric.

Look at the waterfall view for individual page views in AppResponse Xpert and verify it has the beacon.gif request to the BrowserMetrix Collector.

View the page source of a page that should be tracked in the browser to ensure it has the initial JavaScript snippet loaded.

Analyze network packets from the browser workstation with AppTransaction Xpert to verify it makes a request to the BrowserMetrix Collector.

View the transaction details from Transaction Trace Warehouse (assuming the back-end is also instrumented with AppInternals Xpert) to check the HTTP headers for presence of a BrowserMetrix cookie.

Look at AppResponse Xpert data for requests to the BrowserMetrix Collector process to validate they occur.

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.

This is not feasible currently.

Recompile or modify the code.

Set the JAVA_TOOL_OPTIONS environment variable to add the argument into the application start up.

We should not instrument applications that use embedded virtual machines.

Tiers with identical code are deduplicated and correlated for each transaction at run time.

Each trace includes all the tiers necessary to execute the transaction at run time.

Tiers that are identical in the same transaction are excluded at run time.
