Frequent CPU spikes observed on AMS Service

Frequent CPU spikes observed on AMS Service

New Contributor

Hi Team,

 

We are using AMS collector service running on a host, which also has zookeeper and other slave/client services running, we observe frequent spikes on CPU usage on this node for AMS process, even after tuning below parameters as per cluster 21-100 nodes as per below link.

 

metrics_collector_heap_size=1664

hbase_regionserver_heapsize=1024

hbase_master_heapsize=5120

hbase_master_xmn_size=768

Version:

HDP- 3.1.0.0-78

Ambari Metrics - 0.1.0

 

What further tuning is required to fix CPU spikes caused by AMS process.
