1. 创建监控用户
[admin]# obclient -h127.0.0l -P2881 -D -uroot@sys -p -A
obclient [sys]> grant select on oceanbase.* to monitor identified by 'OceanBase010';2. 更新配置文件
参考obagent配置文件：https://github.com/oceanbase/obdeploy/blob/master/example/obagent/obagent-only-example.yaml
编辑obagent.yaml配置文件
[admin]# vi obagent.yaml
obagent:

[admin]# wget https://github.com/prometheus/prometheus/releases/download/v2.43.0/prometheus-2.43.0.linux-amd64.tar.gz
[admin]# tar -zxvf prometheus-2.43.0.linux-amd64.tar.gz
[admin]# cd prometheus-2.43.0.linux-amd64
[admin]# ./prometheus --config.file="/home/admin/obagent/conf/prometheus_config/prometheus.yaml"浏览器访问：http://192.168.1.71:9090/graph
9. 安装Grafana
[admin]# wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.4.7-1.x86_64.rpm
[admin]# sudo rpm -ivh grafana-enterprise-9.4.7-1.x86_64.rpm
[admin]# sudo /bin/systemctl start grafana-server.service然后添加prometheus的数据源（http://192.168.1.71:9090）
可以到grafana官网下载OceanBase提交的监控模版：
oceanbase-metrics_rev2.json
host-metrics_rev1.json
