Heap chart
Heap is the portion of a VM or container’s memory allocated to individual applications.
Turbonomic collects heap data from Application Components discovered by Applications and APM targets. When you set the scope to one or several Application Components, the data that Turbonomic collected displays in the Heap chart.
The chart shows average and peak/low values over time. Use the selector on the chart to change the time frame.
An empty chart could be the result of delayed discovery, target validation failure, unavailable data for the given time frame, or an unsupported Application Component (see the next section for a list of supported Application Components).
Supported application components
Data is available in the Heap chart for Application Components discovered via the following targets:
| Target | Supported application components |
|---|---|
| AppDynamics | Java applications, .NET, Node.js |
| Dynatrace | Java applications |
| Instana | Java applications |
| JBoss | Java applications |
| JVM | Java applications |
| New Relic | Java applications, Node.js |
| Tomcat | Java applications |
| WebLogic | Java applications |
| WebSphere | Java applications |
Heap resize actions
Turbonomic generates Heap resize actions if an Application Component provides Heap and Remaining GC Capacity, and the underlying VM or container provides VMem. These actions are recommend-only and can only be executed outside Turbonomic.
Remaining GC capacity is the measurement of Application Component uptime that is not spent on garbage collection (GC).
