(2)可视化web管理界面。
(3)免费开源。
(4)支持中文。
(5)自动发现。
(6)分布式监控。
(7)实时绘图。
3.zabbix的主要功能
硬件监控。如交换机、路由器、打印机等。
2.系统监控。如CPU,内存,磁盘。硬盘IO,系统负载等。
3.服务监控。如apache,nginx,tomcat,redis,TCP连接数等。
4.性能监控。如网站性能,服务器性能,数据库性能。
5.日志监控。如访问日志,错误日志。
6.安全监控。如用户登录数,本地文件改动,passwd文件变化。
7.网络监控。如端口,SMTP,网络使用率,网络入流量,网络出流量。

二、检查本地k8s环境
1.检查系统pod运行状态
[root@k8s-master ~]# kubectl get pods -ANAMESPACE NAME READY STATUS RESTARTS AGEkube-system calico-kube-controllers-7bc6547ffb-2nf66 1/1 Running 1 (9m28s ago) 2d16hkube-system calico-node-8c4pn 1/1 Running 1 (9m16s ago) 2d16hkube-system calico-node-f28qq 1/1 Running 1 (9m10s ago) 2d16hkube-system calico-node-wmc2j 1/1 Running 1 (9m29s ago) 2d16hkube-system coredns-6d8c4cb4d-6gm4x 1/1 Running 1 (9m28s ago) 2d16hkube-system coredns-6d8c4cb4d-7vxlz 1/1 Running 1 (9m29s ago) 2d16hkube-system etcd-k8s-master 1/1 Running 1 (9m30s ago) 2d16hkube-system kube-apiserver-k8s-master 1/1 Running 1 (9m29s ago) 2d16hkube-system kube-controller-manager-k8s-master 1/1 Running 1 (9m30s ago) 2d16hkube-system kube-proxy-8dfw8 1/1 Running 1 (9m29s ago) 2d16hkube-system kube-proxy-ghzrv 1/1 Running 1 (9m9s ago) 2d16hkube-system kube-proxy-j867z 1/1 Running 1 (9m15s ago) 2d16hkube-system kube-scheduler-k8s-master 1/1 Running 1 (9m28s ago) 2d16h
2.检查node节点状态
[root@k8s-master ~]# kubectl get nodes -owideNAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIMEk8s-master Ready control-plane,master 2d16h v1.23.1 192.168.3.201 <none> CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6k8s-node01 Ready <none> 2d16h v1.23.1 192.168.3.202 <none> CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6k8s-node02 Ready <none> 2d16h v1.23.1 192.168.3.203 <none> CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 containerd://1.6.6
三、配置nfs共享存储
1.安装nfs
yum install -y nfs-utils
2.创建共享目录
mkdir -p /nfs/data
3.配置共享目录
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports
4.启动相关服务
systemctl enable rpcbindsystemctl enable nfs-serversystemctl start rpcbind
5.使配置生效
exportfs -r
6.查看nfs
[root@k8s-master ~]# exportfs/nfs/data <world>
7.其他节点检查nfs共享
[root@k8s-node01 ~]# showmount -e 192.168.3.201Export list for 192.168.3.201:/nfs/data *
四、安装zabbix-mysql
1.编写zabbix-mysql的yaml文件

3.登录zabbix
初始账号admin/zabbix
4.查询zabbix-server的监控项图表
