SAR (System activity Reporter report) is one of the most comprehensive system performance analysis tools available on Linux, which can be used to report the activities of the systems in many ways, including: Read and write of files, usage of system calls, disk I/O, CPU efficiency, Memory usage, process activity, and IPC-related activities. In this paper, the CentOS 6.3 x64 system is introduced as an example

Glances is a Linux, BSD open Source command-line system monitoring tool, which uses the Python language development, uses the Psutil library to collect the system data, can monitor the CPU, the load, the memory, the disk I/O, the network traffic, the file system, the system temperature and so on information. Compared to top/vmstat/iostat and other old monitoring tools
not indicate a ram bottleneck. The virtual memory system often makes page exports to the memory segment, but the page import operation indicates that the server needs more memory, and the page import needs to copy the memory segment from swap disk back to RAM, causing the server to become slower.There are several ways to solve this problem:1. The simplest, increase the RAM;2. Reduce the need for RAM by changing the SGA;3. Reduce the need for RAM. (e.g., reduction of PGA)Reference Documentation:
