Customize AMS memory settings

AMS runs across multiple components, each of which impacts memory use.

Because AMS uses multiple components, such as Apache HBase and Apache Phoenix to store and query metrics, you must consider multiple properties for tuning AMS memory use.
Tune the AMS memory settings using the following properties:
Table 1. AMS Memory Settings
Configuration Property Description
Advanced ams-env metrics_collector_heapsize Heap size configuration for the Collector.
Advanced ams-hbase-env hbase_regionserver_heapsize Heap size configuration for the single AMS HBase Region Server.
