Monitoring agent side clamping value

Issue/Introduction

Would like to monitor agent side clamping value.

Looks like agent side clamped never triggered when Clamped value is reached, and we end up in a situation where we do not know when the agent get clamped.

Resolution

The metric (Example):
SuperDomain|Custom Metric Host (Virtual)|Custom Metric Process (Virtual)|Custom Metric Agent (Virtual)|Agents|xxxxxxx-win19|Infrastructure|Agent:Is Clamped

This above metric only track manager side clamping value and it will change if the manager side clamping is hit.

This above matric does not track agent side clamping value.

Example:

introscope.agent.metricClamp=100000

To track the agent side clamping value, there are a couple of options available.

1- reviewing the agent log to see if the agent side clamping value is hit as it is indicated in the agent log.

2- track the following metric on manager side.
SuperDomain|Custom Metric Host (Virtual)|Custom Metric Process (Virtual)|Custom Metric Agent (Virtual)|Agents|xxxxxxx-win19|Infrastructure|Agent:Metric Count

So, an alert can be configured on this above value when it is above 100000.
