Linux system is by using the vmstat tool. The important Columns in vmstat with respect to I/O are the bi and bo fields. These fields monitor Movement of blocks in and out of the disk subsystem. Having a baseline is key to being able To identify any changes over time. The hard disk tracking tool in Linux can use vmstat, The most important columns are bi and bo. they monitor the movement of input and output

Monitoring is the core task of cluster management. Monitoring data can be used for scheduling tasks, load balancing, reporting hardware and software failures to administrators, and extensive control of system usage. Monitoring information must be obtained without impacting the performance of the cluster. This article discusses ways to obtain monitoring data using the/proc file system and Java. The application of Java in

-identified,However, this method is useful if the problem can be reproduced;. Tracing is the collecting of performance data over time to diagnose a problem. This isGood way to perform remote performance analysis. Some of the drawbacks includePotential for having to analyze large files when performance problems are not repeatable,And the potential for not having a
