Issue/Introduction

.NET APM Agent Losing Metrics after an App Pool is recycled.   

Environment

Release : 14.6

Component : APM Agents

Cause

Connection timing issue.

Resolution

Changed the setting introscope.agent.agentAutoNamingMaximumConnectionDelayInSeconds=240 in the problem environment. And upgraded to APM 20.4 agent.

Additional Information

Still seeing %1 agent. But looking at the "old" (without %1) and new (with %1) agent allows seeing metrics.
