Method for performance measure of special system and management of special process in remote site

摘要

PURPOSE: A method for measuring the system performance and managing a process in a remote place is provided to reduce the port use of a server and to obtain the information by decreasing the load of the corresponding system maximally during measuring the system performance and monitoring the process. CONSTITUTION: The allocated port number is initialized to zero if a server program is started(ST11). After the initialization, a socket file descriptor is set by using a socket function(ST12). The socket file descriptor is joined to the system port by using a binding function(ST13). A listen state is waited until an external connection is entered from the outside by using a listen function(ST14). The connection from the outside is checked at a wait state(ST15). If the connection from the outside exists, the number of the allocated port is confirmed(ST16). If the number is zero, a new port is allocated by using an accept function, and the information is transmitted to the new port(ST17). If the number is not zero, the information is transmitted by using the previously used port(ST18).
