KSM (KAAS Server Monitor) is an event-driven system monitor. It's originally desinged to monitor server status and take necessary actions according to detected server response.

It uses a simple state machine to do the job. User can define and set various methods to detect server status, report failures, and take pre-defined actions. The goal of KSM is not limited in server monitoring, it can be easily extended by using its flexible configuration file.

KSM say hello to server periodically, and checks server response. If the response is invalid, there is a instance of failure. When there is a certain of numbers of failure instance reached, a server failure event is reported. KSM can be configured to send failure report and take necessary actions.

KSM is not limited in server monitoring, althrough it originally designed to do so. KSM can be applied to any job which can be described by above logic.

KSM shows following features:
• Highly configurable in server failure detection.
• Build in HTTP capability through CURL library.
• Support C strftime variable in failure report generation.
• A flexible event-driven state machine, simple to understand.
