Foglight APM for Real User Experience 5.9.11 - User Guide

Overview of APM tiles

Foglight APM includes a tile view for each monitored domain. In order to populate these tiles, the appropriate Foglight cartridge must be installed and configured to monitor the domain or component. For example, in order to view the Application Servers - Java tile, you must install Foglight for Java EE Technologies and configure it to monitor at least one Java™ application server.

The metrics displayed on a tile are specific to the domain, but the overall look and functionality of the tiles are common. For example, the following tile presents JMX data:

Topology Object Name: JMXServer

Alarm State

The icon in the top left corner indicates the current state of alarms for the component.

Title Bar

The title bar includes the component name, and the Explore icon . Click the icon to open a detail view. For more information, see Overview of Detail views.

Component Icon

Each component is represented by a unique icon that provides easy, at-a-glance recognition of the domain.

Key Metric

The most important metric for the domain is displayed in the largest font, directly below the component icon, on the left side of the tile. Where no one metric takes precedence (for example, on the Host tile), the current alarms are displayed instead.

Graphical Summary

The right side of the tile displays a graphical summary of key metrics for the component. For example, the JMX tile includes a health breakdown for MBeans, as in the example above. Other domains include a chart of the key metric for the time range selected (such as Response Time), an overall health history (color-coded bar), or a list of session bottlenecks.

Additional Metrics

Additional metrics that are key to the component appear at the bottom of the tile.

NOTE: The values of these metrics are always current, unless the value appears in italics (for example, GC 0.26%). Italicized metrics reflect the period average instead of the current value.

Application Servers - .NET tile

Use the Application Servers - .NET tile to gather performance information about the state of .NET® transactions monitored by Foglight for Microsoft .NET, version 5.9.x or later.

Topology Object Name: CustomApplicationTransaction

 
Table 24. Description of the Foglight for Microsoft .NET view
Data displayed
•
Hits. The number of calls served in the most recent collection interval.
 
•
Health History Bar. The color-coded bar represents the alarm state of the monitored component over the time range selected in the SOC. The color of the bar changes depending on the alarm state. Red indicates a Fatal state, orange indicates Critical, yellow means Warning, and green is the Normal state.
 
•
Response Time. A plot of the request response time.
 
•
Exceptional Exits. The number of exceptional exits recorded.
 
•
Bottleneck. Indicates the portion of the application where requests are experiencing slowdowns.
 
* 
NOTE: The Foglight application server monitoring solutions, Foglight for Microsoft .NET and Foglight for Java EE Technologies, share a single tile view as of version 5.9.1. For older versions of the Cartridge for Microsoft .NET, see the .NET tile.

.NET tile

Use the .NET tile to gather performance information about the state of .NET® transactions monitored by Foglight for Microsoft .NET, version 5.6.x or earlier.

Data displayed

Alarms. A count of fatal, critical, and warning alarms on the host system.

 

The four top used external resources from the following list are displayed on the tile:

•
Internal. All method calls that are not related to any other call types in this list.
•
Database. Method calls related to databases.
•
Web Svc. Method calls related to web services.
•
Mail. Method calls related to sending mail.
•
Remoting. Method calls related to remoting client-side resources.
•
WCF. Method calls related to WCF client-side resources.
 
•
Load. The average load on the .NET® system.
•
Transaction. The current number of transactions per second.
•
Exception. The current number of exceptions per second.
•
Server. The .NET server name.

Application Servers - Java tile

The Application Servers - Java Tile summarizes the performance of a Java EE system monitored by Foglight for Java EE Technologies. Use this tile to gather performance information about the state of Java™ transactions.

Topology Object Name: CustomApplicationTransaction

 
* 
NOTE: In previous releases, the topology object for the Cartridge for Java EE Technologies was JavaEEAppServer.

If the application server includes Request Types in the selected time range and the server has served at least one request in the selected time range, you can click the title bar to drill down to the Application Server detail view. If there are no request types, clicking the title bar drills down to the server details.
