Hi guys,
We have a question: how we build a chart using data from custom MBean provided by one of the Tomcat infrastructure servers?
On the application side we define an MBean named "PredictiveAutoCall:type=AutoCallStats”. That bean and its attributes are visible through the MBean Browser for the node. However, we need to display data from that bean on a dashboard as charts, and for that we have to create metrics. This is where the problem appears: metrics created in the Tomcat configuration, as well as those created in a specially created AutoCalls configuration, are not displayed in Metric Browser and unavailable for drawing a chart.
Actually the connection between Metric Browser and Configuration>Instrumentation>JMX is not obvious. In our infrastructure we run several Tomcat servers but AutoCallStatsMBean is defined on only one of them. Given that, the JMX settings have no node connection - they are linked just to a configuration. We don’t see how we can configure that AutoCallStatsMBean should be searched on only one specific node or tier.
Our further experiments showed a strange behavior: when we renamed the "JDBC Connection Pools” metric for a Tomcat configuration, browser started to display two metrics: with an old and a new name and same sets of attributes. After we renamed the metric again, there are still 2 metrics in browser. That looks like a bug.
