ABSTRACT:
A server self health monitor (SHM) system monitors the health of the server it resides on. The health of a server is determined by the health of all of a server's sub-systems and deployed applications. The SHM may make health check inquiries to server sub-systems periodically or based on external trigger events. The sub-systems perform self health checks on themselves and provide sub-system health information to requesting entities such as the SHM. Sub-systems self health updates may be based on internal events such as counters or changes in status or based on external entity requests. Corrective action may be performed upon sub-systems by the SHM depending on their health status or the health status of the server. Corrective action may also be performed by a sub-system upon itself.
