一、Ceph内置模块
Ceph manager 内部的模块中包含了 prometheus 的监控模块,并监听在每个 manager 节点的 9283 端口，该端口用于将采集到的信息通过 http 接口向 prometheus 提供数据。
二、监控搭建
1、启用 prometheus 监控模块
ceph mgr module enable prometheus
2、验证模块开启
ceph mgr module ls |less{"always_on_modules": ["balancer","crash","devicehealth","orchestrator","pg_autoscaler","progress","rbd_support","status","telemetry","volumes"],"enabled_modules": ["dashboard","iostat","nfs","prometheus","restful"],"disabled_modules": [{"name": "alerts","can_run": true,"error_string": "","module_options": {"interval": {"name": "interval","type": "secs",
3、验证 mgr 节点端口监听
root@ceph-mgr1:~# ss -lntup | grep 9283
tcp LISTEN 0 5 *:9283 *:* users:(("ceph-mgr",pid=1247,fd=36))
4、查询prometheus指标节点信息
ceph mgr services
查询出prometheus对应的metrics地址信息
5、浏览器访问mgr指标
输入 http://IP:9283
6、集成Prometheus
添加 mgr 节点 metrics 采集任务
vim prometheus.yml
- job_name: "ceph-mgr"static_configs:- targets: ["172.168.100.38:9283"]
重启prometheus
systemctl restart prometheus
prometheus server验证
集成grafana数据大盘
在 grafana 添加 采集 ceph集群的 prometheus 数据源
