Tomcat memory metricset
editTomcat memory metricset
editThis 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.
Memory Metricset retrieves the JMX key java.lang:type=Memory
using Jolokia. It exposes the following metrics:
-
tomcat.memory.heap.usage.committed
: Committed heap memory usage. -
tomcat.memory.heap.usage.max
: Max heap memory usage. -
tomcat.memory.heap.usage.used
: Used heap memory usage. -
tomcat.memory.heap.usage.init
: Initial heap memory usage. -
tomcat.memory.other.usage.committed
: Committed non-heap memory usage. -
tomcat.memory.other.usage.max
: Max non-heap memory usage. -
tomcat.memory.other.usage.used
: Used non-heap memory usage. -
tomcat.memory.other.usage.init
: Initial non-heap memory usage.
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
