然后进去创建访问配置。
prometheus node exporter docker
收集本地系统信息。使用9100端口。
https://github.com/prometheus/node_exporter
上面给出的是3.8版本，需要docker 1.25.5 以上才支持，否则Version in ".\docker-compose.yml" is unsupported.
https://github.com/docker/compose/releases/tag/1.25.5
升级docker版本，或者手动修改下version：
---
version: '3.3'
services:
node_exporter:
image: quay.io/prometheus/node-exporter:latest
container_name: node_exporter
command:
- '--path.rootfs=/host'
network_mode: host
pid: host
restart: unless-stopped
volumes:
- '/:/host:ro,rslave'
然后启动
docker-compose up -d
安装 & 配置 grafana agent
使用apt源：
mkdir -p /etc/apt/keyrings/
wget -q -O - https://apt.grafana.com/gpg.key | gpg --dearmor | sudo tee /etc/apt/keyrings/grafana.gpg > /dev/null
echo "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com stable main" | sudo tee /etc/apt/sources.list.d/grafana.list
sudo apt-get update
sudo apt-get install grafana-agent
或者直接下载二进制包：
# https://github.com/grafana/agent/releases
wget -q https://github.com/grafana/agent/releases/download/v0.38.1/grafana-agent-0.38.1-1.amd64.deb -O /tmp/grafana-agent.deb
dpkg -i /tmp/grafana-agent.deb
rm -f /tmp/grafana-agent.deb
grafana agent默认使用9090端口，如果有冲突就修改。这里改成使用19090、19091：
# port 9090 maybe occupied by, such as cockpit
# change to use 19090, 19091
sed -i -e "s/127.0.0.1:9090/127.0.0.1:19090/g" -e "s/127.0.0.1:9091/127.0.0.1:19091/g" /etc/default/grafana-agent
配置/etc/grafana-agent.yaml。把grafana cloud的账号和url地址填上。
