Issue/Introduction

How  the APM Loadbalancing algorithm work in SaaS?

Environment

APM SaaS 

Resolution

The LB algorithm computes two utilization values in percentage for each collector.

  * agent count utilization

  * metric count utilization

Both values are in percentage so they can be aggregated and none of them has a precedence.

 

"total utilization" of the collector is defined as max value of agent count utilization and metric count utilization. When an agent asks to be connected the loadbalancer picks the collector with the smallest "total utilization".
