为方便问题发生后,问题原因的分析排查,我们可以在服务器中事先部署如下脚本,方便故障发生后,问题原因的分析排查
脚本部署方法:
1.将脚本【linux_reports.sh】上传到服务器
2.登陆虚拟机,并切换到root用户
3.执行命令: chmod +x <path>/linux-reports.sh 【<path>替换成实际脚本上传的目录】
4.执行命令:crontab -e
5.添加定时任务:* * * * * <the path of the script>/linux-reports.sh <ouputs name> <keeps>
备注:
范例:*/6 * * * * /root/linux-reports.sh performancelog 120 &
a.performancelog为输出日志名称k,可以根据实际情况任意指定
b.120为性能数据保留的最长期限,单位为分钟。比如120,就是代表所有的性能数据收集的时间在120分钟之内的予以保留,超过120分钟的会被删除。如果想保留超过一天及以上的,只有输入确定的分钟数即可,比如保留三天,那么分钟数为4320。
c.所有的性能数据都存放在目录/var/tmp/下. 命名类似:
6.可以通过如下方法查看搜集到的性能日志:
1 2 3 4 5 6 7 8 9 10 11 12 | gunzip performancelog_hlmcent69nma_070001-22-Nov-2017. tar .gz tar xvf performancelog_hlmcent69nma_070001-22-Nov-2017. tar cd hlmcent69nma_070001-22-Nov-2017/ [root@hlmcent69nma hlmcent69nma_070001-22-Nov-2017] # ll total 28 drwxr-xr-x. 2 root root 4096 Nov 22 07:00 cpu drwxr-xr-x. 2 root root 4096 Nov 22 07:00 disks drwxr-xr-x. 2 root root 4096 Nov 22 07:00 log drwxr-xr-x. 2 root root 4096 Nov 22 07:00 memory drwxr-xr-x. 2 root root 4096 Nov 22 07:00 network drwxr-xr-x. 2 root root 4096 Nov 22 07:00 sar -rw-r--r--. 1 root root 489 Nov 22 07:00 vminfo |
