Health status monitoring for services provided by computing devices

A server computing device for monitoring a status of a service, the server computing device comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the server computing device to implement a monitoring agent associated with a service, wherein the monitoring agent is configured to:
• receive a health check message from a health check engine over a network interface;
• generate the status of the service based on a status of each of a plurality of service instances;
• and
• transmit the status of the service to the health check engine.

At least one non-transitory computer readable storage medium configured to store instructions that, when executed by at least one processor included in a server computing device, cause the server computing device to monitor a status of a service instance, by carrying out steps that include:

• collecting statistics associated with one or more service dependencies of the service instance during a tracking window;
• calculating a ratio of successful responses to failed responses in a plurality of responses generated by the service instance during the tracking window;
• and
• generating the status of the service instance by comparing the ratio to a threshold value.
