A distributed environment requires a monitoring system to oversee the operation of various distributed nodes. A monitoring service is crucial because it ensures a high-quality computing environment and a reliable service. The interface and framework determine the effectiveness of a monitoring system. This paper uses the concept of user-adaptive visualization to design its interface and proposes a flexible modular framework. Designers can use the proposed modular framework to flexibly extend existing modules, design visual interfaces to satisfy user requirements, and improve system failover schemes. The implementation of such a monitoring system for monitoring data preservation nodes is also provided. The system including faulttolerance and notification functions supports full monitoring services for Storage Resource Broker (SRB) or integrated Rule-Oriented Data System (iRODS) based systems. The experimental results show that the proposed framework is suitable for data preservation services and is robust and responsive when faced with system failures. Disk free space, CPU load, SRB connect check, DB status, oracle error check, SRB error check, iROD check, temperature, output current, output frequency, main battery, battery capacity, output voltage, and PING and SSH Number of events 87,457,019customizable. These features ensure lower overheads and costs, but also increased robustness and responsiveness. Future studies should explore more advanced framework applications, including security auditing and resource performance tuning. Functionality should also be extended to match other data transfer systems, protocols, and cloud computing services. T.-Y. CHEN ET AL.
