Agent functionality evaluation in managed endpoints

A non-transitory computer-readable medium having encoded therein programming code executable by one or more processors to perform or control performance of operations of health and functionality evaluation of an agent on a managed endpoint, the operations comprising:

• receiving, at a service bus, an agent event message, wherein the agent event message includes data representative of a current status of the agent loaded on the managed endpoint, the agent event message is communicated when the agent checks in with a cloud management device, the agent event message includes first data representing platform health indicators and second data representing capacity health indicators, the platform health indicators are quantifications of functionality of communication channels and components that implement the agent on the managed endpoint, the capacity health indicators are quantifications of functionality of engines that are configured to implement a management operation at the agent, and the first data and the second data are communicated separately;
• examining, by a series of detectors, the agent event message for a change in status of at least one aspect of health of the agent;
• responsive to the agent event message indicating the change, emitting, by the series of detectors, an updated agent event;
• triggering generation of a health score of the agent based on the updated agent event and historical agent health data, the health score representing a current level of functionality degradation of the agent that is based on an agent platform health and health of the engines delivered on the managed endpoint;
• communicating to a webhost the health score;
• and
• causing display, on a web-hosted user interface, the health score of the agent.
