Prometheus Server
Prometheus Server 本身也將以容器的方式運(yùn)行在 host 192.168.56.103 上授帕。
Exporter
Prometheus 有很多現(xiàn)成的 Exporter伐蒋，完整列表請(qǐng)參考 https://prometheus.io/docs/instrumenting/exporters/
-
我們將使用：
Node Exporter，負(fù)責(zé)收集 host 硬件和操作系統(tǒng)數(shù)據(jù)蛙讥。它將以容器方式運(yùn)行在所有 host 上。
cAdvisor，負(fù)責(zé)收集容器數(shù)據(jù)讼油。它將以容器方式運(yùn)行在所有 host 上晓折。
安裝Node Exporter
docker run -d \
-v "/proc:/host/proc" \
-v "/sys:/host/sys" \
-v "/:/rootfs" \
--net=host \
prom/node-exporter \
--path.procfs /host/proc \
--path.sysfs /host/sys \
--collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"
ip + 端口 驗(yàn)證
使用--net = host 方便通信
- 各節(jié)點(diǎn)運(yùn)行 cAdvisor惑朦，用來監(jiān)控容器
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
