Tomcat requests metricsetedit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

Requests Metricset retrieves the JMX key Catalina:name=*,type=GlobalRequestProcessor using Jolokia. It exposes the following metrics:

  • tomcat.requests.mbean: Number of requests processed
  • Number of requests processed
  • tomcat.requests.bytes.received: Amount of data received, in bytes
  • tomcat.requests.bytes.sent: Amount of data sent, in bytes
  • Total time to process the requests
  • Number of errors

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.


For a description of each field in the metricset, see the exported fields section.
