监控对比

zabbix

• 优点
  • 报警系统
  • 图表展示好
  • Creation of new alerts - either fault based or performance based.

• Creating an alert & its trigger can be made easier.
• More VM-based data collection counters should be introduced to have better VM monitoring.
• The raw counters collection agent in every node is relatively weak. It goes down often, which needs more stability.

ifconfig eth0 |awk 'NR==2{print $2}' # 输出IP,如果没有制表符，则第二列不好输出
## 关闭防火墙
systemctl disable --now firewalld
getenforce # 查看是否关闭
iptables -L # 查看流量是否允许过来
free -m # 内存大点，至少两个G, 4G最好
