It uses a window, not a port.

Large network transfer effects and large protocol delays

Several paths are used to receive traffic, so packets can be received out of order.

A TCP retransmission when looking at a trace on the sender side.

A TCP retransmission when looking at a trace on the receiver side.

It cannnot indicate a TCP retransmission. That is recorded using the TCP retransmission statistic only.

The Web tier is the bottleneck because it has the most open requests waiting for a response.

The DB tier is the bottleneck because it is the lowest tier that is clearly not handling requests in time.

The App tier is the bottleneck because it is the first tier not handling the same number of requests as the tier above it.

The Web tier is the bottleneck because at an Offered Load of 300, there are still 50 requests waiting from the Web tier, and it never recovers. The lower tiers do not get the requests passed to them because the Web tier is not processing fast enough.

The App tier is the bottleneck because the DB tier is handling everything the App tier sends it.

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

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.

Some code compilation or modification is needed.

You can set the IBM_JAVA_OPTIONS environment variable to add the argument into the application startup.

IBM SDK Java is not supported.

Setting the IBM_JAVA_OPTIONS environment variable will add the same argument into every IBM SDK Java application startup.

Response time for SQL statements

Database usage by application and user

It tracks throughput in terms of database calls, transactions, rows, bytes, and active sessions.

You get of list of next-hop IP addresses or host names to use to create dashboards.

The field automatically populates with the data sources for the IP address or host names from which you can open pre-configured dashboards.

The "Create New Dashboard" panel opens with templates you can use to create a dashboard with the given IP address or host name.

The dashboards already created with the given IP address or host name automatically open in a new tab.

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.
