As long as a user can view the dashboard, they can make their own local edits.

The user has to own the dashboard to be able to do full editing.

The owner can grant specific users full access.

By default, anyone who can authenticate to the OPNET Authorization Server can create their own dashboard.

Dashboards can be shared so that authentication is not required, and right-click integration is fully functional.

Being able to view a dashboard panel lets you adjust its time range and copy the panel to your own dashboard for further editing.

External content can be inserted into any dashboard by using the Auxiliary Panel content type.

Traffic capture using capture agents

Ability to decode web application traffic

Ability to run Multi User Quick Predict (MUQP)

Integration with the AppResponse Xpert appliance

Using Wireshark to decode the trace is recommended.

Using Wireshark to decode the trace is mandatory.

AppTransaction Xpert uses its internal decoder to decode the trace.

AppTransaction Xpert uses trace explorer to decode the trace.

From AppTransaction Xpert, use the AppTransaction Xpert capture manager

From AppSensor Xpert, when defining synthetic tests

From AppResponse Xpert, use the packet download manager

Using the distributed agent controller

From the packet trace warehouse

Estimate connectivity to capture agents

Ports cannot be changed after the installation.

Change the server.xml HTTP_PORT and HTTPS_PORT specifications in the installation folder.

Changes are need on both server.xml and bindings-jboss-beans.xml.

Log in to the BrowserMetrix default web user interface.

Safari does not support the W3C Navigation Timing specification.

Safari is a more responsive browser.

BrowserMetrix does not process "time to first byte" currently.

This is the user's first visit to the site or the previous page was not one of the instrumented pages.

Use Riverbed Steelhead to inject the script at run time from the web server.

Use Riverbed Stingray to inject the script at run time from the web server.

Manually paste the Javascript in any web page you want to monitor with BrowserMetrix.

Edit a master file for the application by adding the Javascript to the header section of the file.

By default, the DSA attempts to keep 1-second data for 2 hours. The length of this time period is specified by the RawDataPersistDuration attribute in the dsa.xml file.

The DSA deletes the oldest 1-second data from the database If there is less than 10 percent of free disk space (the default for the RawDataPersistFreeSpaceTargetPercent attribute)

The DSA deletes the oldest 1-second data from the database if the database file is larger than specified in the RawDataPersistMaxDiskTarget attribute (unlimited as default).

If both the RawDataPersistFreeSpaceTargetPercent and RawDataPersistMaxDiskTarget attributes are satisfied, the DSA deletes data, if necessary, to retain only as much data as specified by RawDataPersistDuration.

At startup, and every 2 hours thereafter (or the frequency specified by RawDataPersistPurgeInterval), the DSA deletes the oldest 1-second data from the database.

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.

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.

Route clients around the load balancer.

Create a firewall rule to ensure the client IP addresses are seen.

Specify a route in the router for the client IP addresses.

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.

AppResponse Xpert, because it shows server and network delays for individual page views.

AppInternals Xpert Transaction Trace Warehouse, because it includes network delay and indicates what happens within each tier.

BrowserMetrix SaaS, because it reports the most detail of end-user performance, is measured at the browser, and is easiest to set up.

AppTransaction Xpert, because it reports the most detail of transaction performance as seen by the workstation's network packets.

BrowserMetrix On-Premise, because it provides the most detail of end-user performance and the ability to see Transaction Trace Warehouse data for server-side delay information.

The servers cannot be the problem.

It must be the network.

There is no problem. The user's experience is normal and expected.

No conclusion can be made due to insufficient data.

More monitoring and analysis is required to identify and eradicate monitoring gaps at the end user, network, server, and back-end dependencies.
