zabbix集成寡妇

https://grafana.com/

## 1.安装grafana
[root@zabbix ~]# yum install -y https://dl.grafana.com/enterprise/release/grafana-enterprise-9.1.1-1.x86_64.rpm

## 2.启动grafana
[root@zabbix ~]# systemctl start grafana-server

## 3.检查端口
[root@zabbix ~]# netstat -lntup|grep 3000
tcp6       0      0 :::3000                 :::*                    LISTEN      1372/grafana-server

## 4.打开浏览器访问

## 如果zabbix无法安装，需手动安装
[root@web01-zbx ~]# grafana-cli plugins install alexanderzobnin-zabbix-app
✔ Downloaded alexanderzobnin-zabbix-app v4.2.9 zip successfully
[root@web01-zbx ~]# systemctl restart grafana-server

zabbix性能调优

1. Zabbix属于写多读少的业务, 所以需要针对zabbix的MySQL进行拆分。MySQL一定要使用SSD固态盘

2. 将Zabbix-Agent被动监控模式, 调整为主动监控模式。

3. 使用zabbix-proxy分布式监控, 在大规模监控时用于缓解Zabbix-Server压力

4. 去掉无用监控项, 增加监控项的取值间隔, 减少历史数据保存周期(由housekeeper进程定时清理)

5)针对于Zabbix-server进程调优, 谁忙就加大谁的进程数量, 具体取决实际情况, 不是越大越好

[root@zabbix ~]# vim /etc/zabbix/zabbix_server.conf
StartPollers=20
StartPollersUnreachable=20

6)针对于Zabbix-server缓存调优, 谁的剩余内存少, 就加大它的缓存值(zabbix cache usage图表)

[root@web02 ~]# vim /etc/zabbix/zabbix_server.conf
CacheSize=8M
HistoryCacheSize=16M
HistoryIndexCacheSize=4M

7. 关注管理->队列, 是否有被延迟执行的监控项
