TRACKING DIGITAL CERTIFICATE USAGE THROUGH INSTRUMENTATION

摘要

An embodiment of a system is disclosed in which a monitoring computer system may store instrumentation program code, and then copy the instrumentation program code into a server computer system without modifying a communication application module stored in the server computer system. The instrumentation program code, when executed, may causes the server computer system to perform operations including, for example, intercepting a message sent by a client computer system to the communication application module, and detecting a digital certificate included in the message. The instrumentation program code may further cause the server computer system to perform operations such as determining an expiration time of the digital certificate, and initiating a renewal of the digital certificate.
