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.

A method and apparatus are provided for performing health check requests on one or more network devices or network resources. The method and apparatus provide a build tool for building a health check request having an extensible data format adaptable to a protocol supported by the network device or network resource of concern. The health check request can be built using data captured from a unit of network traffic on a transmission medium or with data provided via a user interface, or a combination of both. A health check request built using the method or apparatus can support any protocol including proprietary protocols avoiding the need for a requestor to learn a protocol format in order to build a health check request checking an operational characteristic of a network device or network resource. The method and apparatus allow this to be accomplished using data captured from a successful transaction.
