Runtimes Support for Red Hat Lightspeed
Red Hat JBoss Enterprise Application Platform
JBoss Enterprise Application Platform (JBoss EAP) 7.4 Update 11 and 8.0 GA onward, contain the insights-java-client. The insights-java-client is enabled for JBoss EAP only if JBoss EAP is installed on Red Hat Enterprise Linux (RHEL), and the RHEL application has insights-java-client installed, configured, and registered. For more information, see the Client Configuration Guide for Red Hat Lightspeed.
Note: An issue in JBoss EAP Update 11 can cause an Out of Memory error on startup for JBoss EAP instances running with a small heap size and large number of deployments, when JBoss EAP is on RHEL with the insights-client installed. Until the bug is fixed, for JBoss EAP instances with a small heap size can disable Insights as shown here. This issue has been fixed in This content is not included.JBoss EAP Update 12 and later versions.
What data does the insights-client collect?
JBoss EAP insights-java-client collects and sends the following data to Red Hat Lightspeed:
- Server configuration which is trimmed of all sensitive data.
- List of all applications deployed on JBoss EAP and their respective jar file names and hashes.
- List of all the jar file names and hashes that are available in the classpath of the server.
- JBoss EAP server installation details such as JBoss EAP versions, JBoss EAP XP versions, information if JBoss EAP uses its Git integration to manage configuration.
If you set the logging level to DEBUG for the category org.jboss.eap.insights.report , you can get the EAP specific JSON payload in the log files.
Configuration options
The in-process clients are configured using a combination of environment variables and system properties. You can use the following environment variables to configure the insights-client available with JBoss EAP.
| Environment variable | Java System Property | Description | Default value |
|---|---|---|---|
| RHT_INSIGHTS_JAVA_OPT_OUT | rht.insights.java.opt.out | Opt out of Red Hat Lightspeed | false |
| RHT_INSIGHTS_JAVA_PROXY_HOST | rht.insights.java.proxy.host | Host name of the proxy server | |
| RHT_INSIGHTS_JAVA_PROXY_PORT | rht.insights.java.proxy.port | Port number of the proxy server |
Note: You can also set these configuration options using Java system properties. However, the environment variables take precedence over the Java system property.
Red Hat Data Grid
Red Hat Data Grid 8.4 Update 7 onward, contains the insights-java-client. The insights-java-client is enabled only if Red Hat Data Grid is installed on Red Hat Enterprise Linux (RHEL), and the RHEL system has insights-java-client installed, configured, and registered. For more information, see the Client Configuration Guide for Red Hat Lightspeed.
