SYSSTAT是一个软件包,包含监测系统性能及效率的一组工具,这些工具对于我们收集系统性能数据,比如CPU使用率、硬盘和网络吞吐数据,这些数据的收集和分析,有利于我们判断系统是否正常运行,是提高系统运行效率、安全运行服务器的得力助手;
sysstat 10.1.4 发布了,包括改进有:
sar, pidstat, and mpstat now stop and display their average statistics when they receive a SIGINT signal (crtl/c).
pidstat now displays the task's UID for all tasks.
The option -U has been added to pidstat; this option tells it to display the username of the task instead of its UID.
When this option is followed by a user name, only tasks belonging to the specified user are displayed by pidstat
