In FortiSIEM, an agent’s status of "Running Inactive" indicates that the agent is installed and running but not actively sending data or has encountered a misconfiguration. The following reasons can cause this status:

1. The agent was registered incorrectly

If an agent was not registered properly, it might not establish a proper connection with the FortiSIEM system, resulting in an inactive status.

2. The agent is temporarily down

If the agent goes offline (e.g., due to system shutdown, network issues, or agent crash), it will show as inactive.

3. The template was not assigned

Agents require a template to function correctly. If no template is assigned, the agent cannot collect or process events, leading to an inactive state.
