Followed the instructions for setting up JVM Metrics (JVMs page (Java): View app server metrics from JMX | New Relic Documentation). Our spring boot application is served via embedded Tomcat web server. The JVM metrics for Memory and Threads are shown. But the Http sessions tab show always an empty chart. The data sources tab shows " There are currently no metrics to display here for your Application Server". Why there is no http sessions metrics data collected from Tomcat server?
spring boot version: 2.2.5
