sysstat
system performance tools for Linux The sysstat package contains the following system performance tools:
- sar: collects and reports system activity information;
- iostat: reports CPU utilization and disk I/O statistics;
- tapestat: reports statistics for tapes connected to the system;
- mpstat: reports global and per-processor statistics;
- pidstat: reports statistics for Linux tasks (processes);
- sadf: displays data collected by sar in various formats;
- cifsiostat: reports I/O statistics for CIFS filesystems.
sudo apt install sysstat
使用问题
服务未开启
➜ ~ sudo sar -d
无法打开 /var/log/sysstat/sa16: 没有那个文件或目录
请检查是否允许数据收集
解决办法:
编辑/etc/default/sysstat, 将 ENABLED="false"改为ENABLED="true", 然后sudo /etc/init.d/sysstat restart
sar
每1秒打印一次各网络接口的数据收发情况，打印1000次：sudo sar -n DEV 1 1000
每1秒打印一次块设备的数据收发情况，打印1000次: sudo sar -d 1 1000
每1秒打印一次中断次，打印1000次: sudo sar -I SUM 1 1000
联想X1 Extreme Gen3安装debian后没有wifi驱动
sudo apt install firmware-iwlwifi
