Performance by Server

This CA Application Delivery Analysis view provides information about how servers are performing. This view displays performance data from the last 24 hours. If the time period for the report is longer than 24 hours, the view only displays performance data for the most recent 24 hours.

If you have enough observations, and if a threshold is available for each combination of application, server, network, and 5-minute period, CA Application Delivery Analysis classifies the metric using one of these ratings:

Acknowledged

Displays a severity state (diagonal stripes) to indicate a CA Application Delivery Analysis or CA Performance Center user acknowledged an incident. When this happens, the CA Performance Center marks data the incident covers as Acknowledged. CA Application Delivery Analysis automatically marks future data covered by an acknowledged incident as Acknowledged.

No Data

Displays a severity state (blank) to indicate no data is available.

Unrated

Displays a severity state (gray) to indicate that either there is insufficient past data (two full business days of data are needed) to establish a threshold, or there were not enough observations to exceed the minimum observations threshold.

Normal

Displays a severity state (green) to indicate the metric value is between zero and the Minor threshold.

Minor

Displays a severity state (yellow) to indicate that the metric value exceeds the Minor threshold as defined in the CA Application Delivery Analysis management console.

Major

Displays a severity state (orange) to indicate that the metric value exceeds the Major threshold as defined in the CA Application Delivery Analysis management console.

Unavailable

Displays a severity state (red) to indicate the application on a server is not running (unavailable). This rating appears when you click All Server Metrics in Settings. This rating is only applicable to a user-defined application where the CA Application Delivery Analysis administrator has assigned servers to the application.

To isolate the component and metric contributing to a performance problem, click one of the worst-performing items at the top of the graph.

Or, edit the filter criteria for the view. By default, all data is included. Filter criteria include:

Metric Type

Select the Server metrics A Server metric indicates that an application performance problem is caused by a server that hosts the application. Use the CA ADA management console to customize the performance thresholds for each of the following Server metrics: Server Response Time, Server Connection Time, Refused Session Percentage, and Unresponsive Session Percentage., Network metrics 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 metrics 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. you want to use to filter the list of networks.
