Overview of CA Application Delivery Analysis Data

The CA Application Delivery Analysis product documentation provides information for interpreting report data and for diagnosing issues that stem from a monitored network, server, or application.

The metric that serves as a starting point for any troubleshooting activity is transaction time, another term for response time. A transaction consists of the following components:

• One request and one server response
• One period of data transfer
• One or more acknowledgments
• Observed latency from retransmitted packets

CA Application Delivery Analysis data identifies performance from the network perspective. Corresponding data in an analysis highlights activity and performance data with multiple views of TCP sessions, volume statistics, and response times. As you investigate a performance issue, consider the transaction time and related metrics such as throughput.

Note: Session-level performance data is available only for the IPv4-based port mirror data that is received on the Multi-Port Monitor logical ports. Session level data is not available for the packet digest data from NI GigaStor or from WAE devices.

The process is as follows:

• Click Session Analysis in an CA Application Delivery Analysis report.
• CA Application Delivery Analysis passes information to Multi-Port Monitor to identify the context and time frame of the data for the selected network, server, or application.
• In a separate browser window, the Multi-Port Monitor web interface opens to the Analysis page. Data is filtered to display relevant performance data for the selected context. The graphs in an analysis look different from the graphs displayed in CA Application Delivery Analysis because Multi-Port Monitor data is available in 1-minute increments. The smallest CA Application Delivery Analysis reporting interval is 5 minutes.

  Averaging of metrics is also different because of the different reporting interval lengths. Your configuration determines whether data displayed in the analysis appears in the management console. For example, data from networks that are not defined in CA Application Delivery Analysis is available only in the analysis.

• You can apply more filters, select different chart formats, change the time frame, and save custom analyses.
