CA Application Performance Management (APM / Wily / Introscope)

Issue/Introduction

Seeing metric gaps in our .NET Agents.  The agent log did capture some clamp limited being reached in the past, e.g. for instances:

[INFO] [IntroscopeAgent.Agent] Statement Normalizer: number of times the extension returned null has hit clamp limit. Further failures will not be logged    
[INFO] [IntroscopeAgent.Agent] Absolute URL metric clamp of 5 reached, All metics will now report under the Default group.    
[INFO] [IntroscopeAgent.WilyTransactionStructure] Head filter check has reached component clamp at 30    

 

 

Environment

Release : 10.7.0

Component : Introscope .NET

Resolution

IIS application time out action is set to terminate.  Thus when the app is not running, it will terminate and cause the Agent to stop as there is nothing to monitor.  This is causing the gaps in metrics.
