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.
Advanced ams-hbase-env	hbase_master_heapsize	Heap size configuration for the single AMS HBase Master.
Advanced ams-hbase-env	regionserver_xmn_size	Maximum value for the young generation heap size for the single AMS HBase RegionServer.
Advanced ams-hbase-env	hbase_master_xmn_size	Maximum value for the young generation heap size for the single AMS HBase Master.
