Issue/Introduction

We have some APMIA agents that are not showing on APM UI. We see following messages in the agent logs:

 

[INFO] [IntroscopeAgent.IsengardServerConnectionManager] Connected controllable Agent to the Introscope Enterprise Manager at HostName:PORT,com.wily.isengard.client.transport.websocket.SSLWebSocketFactory. Host = "HOSTNAME", Process = "Infrastructure", Agent Name = "Agent", Active = "false".

[INFO] [IntroscopeAgent.InfrastructureAgent] New list accepted

 

[INFO] [IntroscopeAgent.ConnectionThread] Connected to HostName:PORT,com.wily.isengard.client.transport.websocket.SSLWebSocketFactory in disallowed mode.

Environment

Release : 20.2

Component : APM Agents

Resolution

DX APM SAAS team resized the tenant, after the resize of the tenant there are no agents in disallowed mode. The tenant appeared to max out at the 1.5M metric limit with less than 100 agents. It is recommended to review the agent configuration to understand why having such high metric count with just small number of agents and possibly tune the agent configurations to reduce the excessive metric reporting.
