使用prometheus和grafana监控ceph集群

在安装了ceph的mon节点上（ip：192.168.20.150），执行一下命令

wget http://static.zybuluo.com/zphj1987/jiwx305b8q1hwc5uulo0z7ft/ceph_exporter-2.0.0-1.x86_64.rpm

rpm -qpl ceph_exporter-2.0.0-1.x86_64.rpm

rpm -ivh ceph_exporter-2.0.0-1.x86_64.rpm

systemctl start ceph_exporter

wget http://static.zybuluo.com/zphj1987/7ro7up6r03kx52rkwy1qjuwm/prometheus-2.3.2-1.x86_64.rpm

rpm -qpl prometheus-2.3.2-1.x86_64.rpm

rpm -ivh prometheus-2.3.2-1.x86_64.rpm

systemctl start prometheus

wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.2.1-1.x86_64.rpm

yum localinstall grafana-5.2.1-1.x86_64.rpm

systemctl start grafana-server.service

 

之后页面上输入地址：http://192.168.20.150:3000

默认用户名密码:admin/admin

之后添加prometheus数据源

 

导入模板 
ceph 的 Dashboard 模板可用从这里下载 https://github.com/magine1989/Ceph_Prometheus_Grafana

然后导入，分别导入3个Dashboard 

导入后就可以看到了 

点进去就可以看到数据了（exporter选择如下图所示的）
