Real Time Network Server Monitoring using Smartphone with Dynamic Load Balancing


Dhuha Basheer Abdullah and Zeena Abdulgafar Thanoon

The services provided by network servers are very important, therefore, the monitoring of these servers in real time is required to discover the obstacles in order to improve servers performance. In this paper, a file server system was designed to be monitored by a smartphone in real time through the use of dynamic scheduling algorithm for three main metrics: CPU usage, Memory usage and Free hard disk space. Dynamic load balancing (DLB) was implemented between servers depending on CPU usage of servers. Also, a dynamic checkpoint (DCP) technique was introduced to minimize files download time. The experiments show that the use of DLB reduced the CPU Usage for both servers and the download time for all clients. Also, the use of the proposed DCP technique is more efficient than the traditional static checkpoint technique.

Keywords: Real time, dynamic load balancing, checkpoint, smartphone
