Ambari Server Performance - This alert appears when the size of the below API call does not respond back within the threshold limit configured in the alert notifications. The reason for this could be the content of the API response just got bigger over the releases.

curl: http://<host>:<port>api/v1/clusters/<clustername>;

Ambari alert sample:

Alert 1: (Time : 01 December 2016 19:42) 
CRITICAL Ambari Server Performance 
Performance Overview: Database Access (Request By Status): 1ms (OK) Database Access (Task Status Aggregation): 1ms (OK) REST API (Cluster): 16,454ms (CRITICAL) 
Cluster: <clustername> 
Alert2 : (Time : 02 December 2016 10:40 ) 
Ambari Server Performance 
Performance Overview: Database Access (Request By Status): 1ms (OK) Database Access (Task Status Aggregation): 1ms (OK) REST API (Cluster): 8,544ms (CRITICAL) 
Cluster: <clustername>

Possible fix:

Increase the threshold limit configured in the alert notification or disable the alert. In future releases of Ambari, this alert will be modified to ask for less information.

Thanks!
