Preconditions:

• Kibana Environment should exist.
• Endpoint security and Agent should be installed

Steps to Reproduce:

1. Navigate to 'Integration' tab under 'Fleet' section.
2. Add Endpoint Security Integration to existing 'Default Policy'.
3. Navigate to 'Policies' tab and Click on Edit button of Endpoint Security Integration policy.
4. Now update your Integration Policy to Detect Mode and Save the changes.
5. Now enroll an Agent from 'Agents' tab. Notice that the agent has been installed successfully and is in Healthy state
6. After Sometime, Observe that Agents runs into an 'Unhealthy' state and KPI count is displayed as '0' under 'Unhealthy' header on Agents table.

Expected Result:
Agents should remain in 'Healthy' state and KPI count should display correct count for all the Status header on Agents table.

What's working:
This issue is not occurring if the agent is in Healthy state

What's not working:
Status ribbon remains Green if the Agent went into an Unhealthy State
It should be displayed as 'Yellow' instead as per color coding

we can confirm this after the changes for Fleet Server are found working - it may be a dupe of one fixed already as part of development.

Hi @EricDavisX ,

We are closing this for now as per our comment posted on #93910_ comment.

We will re-open it if found it reproducible on later builds.

Thanks
