Health check as a service

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a computer system, cause the computer system to perform operations comprising:

• receiving, at the computer system and from a requesting entity separate from the computer system, a request to perform a health check for a network environment associated with a set of multiple flows;
• obtaining, with the computer system and from a network analytics engine, flow information associated with a set of multiple flows;
• selecting, with the computer system and from the set of multiple flows, a subset for the health check, wherein the subset includes (a) a first flow between a first endpoint comprising a first virtualized computing instance (VCI) and a second endpoint and (b) a second flow between a third endpoint comprising a second VCI and a fourth endpoint;
• initiating, with the computer system, the health check for the subset by generating and sending (a) a first instruction to a first management entity to instruct a first host to inject first health check packet for forwarding between the first pair of endpoints of the first flow, and (b) a second instruction to the first management entity or a second management entity to instruct a second host to inject a second health check packet for forwarding between the second pair of endpoints of the second wherein each of the first management entity and the second management entity is a management plane entity or a control plane entity, the first endpoint executes on the first host, and the third endpoint executes on the second host;
• receiving, at the computer system, first report information, generated by a first observation point on a data path between the first endpoint and the second endpoint and triggered by the first health check packet, and second report information, generated by a second observation point or the first observation point on a data path between the third endpoint and the fourth endpoint and triggered by the second health check packet;
• and
• determining, at the computer system and based at least in part on the first report information and the second report information, health status information associated with the subset.
