Issue/Introduction

  Question:  

  What does the heuristic metric IS Clamped represent?

 

  Answer:  

  The metric  "Custom Metric Host (Virtual) - Custom Metric Process (Virtual) - Custom Metric Agent (Virtual)(SuperDomain) - <Host_Name> - <Process_Name> -    <Agent_Name> - IS Clamped"  is entirely controlled by the EM Agent clamp settings defined in apm-events-threshold-config.xml

 

 

  The clamp property is set by  introscope.enterprisemanager.agent.metrics.limit

 

   Once the clamp hits, a new metric must report to the EM for the "IS Clamped" metric to be displayed as 1. 

   This can raise some confusion as there can be instances where an agent is clamped by the EM, but the "IS Clamped" metric is still reporting 0.
