Engineering Trend

This CA Application Delivery Analysis view provides an engineering chart for a particular Server metric, Network metric A Network metric indicates an application performance problem is caused by a network that is communicating with the application. Use the CA Application Delivery Analysis management console to customize the performance thresholds for each of the following Network metrics: Network Round Trip Time, Network Connection Time, Effective Network Round Trip Time, and Retransmission Delay. or Combined metric A Combined metric indicates that an application performance problem is caused by either a server that hosts the application or a network that is communicating with the application, or both. The CA ADA management console sets a performance threshold for each of the following Combined metrics: Data Transfer Time and Transaction Time. Note that the management console does not create application incidents. However, because Combined metrics include both Network and Server metrics, the management console can rate a server or network as Minor (yellow) or Major (orange), and rate the corresponding performance impact on the application itself. For example, if a Server metric is rated as Minor, the management console can also rate a Combined metric for the application as Minor..

If baseline The baseline data that is plotted in many views shows statistical deviations from "normal" performance for a given statistic. Metrics are considered to be "normal" based on the calculated baseline average. The way the baseline is calculated varies by the registered data source. The Standard Deviation is used to gauge the statistical validity of the baseline values. Baseline values are included in charts to help you see places where performance values are changing rapidly. data is applicable, the grey line indicates the number of observations. Not every metric supports baseline or observation data.

Note: This view does not support data from multiple data sources. If you registered multiple instances of CA Application Delivery Analysis, edit the view to filter by one data source. Or change the dashboard group context by clicking the Group link. Using either method, you can select one data source in the Groups tree to serve as the view context.

Configure this view to measure application performance using any of the available CA Application Delivery Analysis metrics. If you receive an incident notification, or notice degraded performance, use this view to quickly drill to the Components reports on the Engineering report of the CA Application Delivery Analysis management console and begin troubleshooting the metric details for the selected application.

Edit the filter criteria for the view to display performance information for a different metric.
