Prometheus + Grafana 疾速上手,监控主机的 CPU, GPU, MEM, IO 等状态。

前提

  • Docker

客户端

Node Exporter

用于采集 UNIX 内核主机的数据,这里下载并解压:

wget https://github.com/prometheus/node_exporter/releases/download/v1.1.2/node_exporter-1.1.2.linux-amd64.tar.gztar xvfz node_exporter-1.1.2.linux-amd64.tar.gzcd node_exporter-1.1.2.linux-amd64nohup ./node_exporter &

查看数据:

$ curl http://localhost:9100/metrics# HELP go_gc_duration_seconds A summary of the pause duration of garbage collection cycles.# TYPE go_gc_duration_seconds summarygo_gc_duration_seconds{quantile="0"} 0go_gc_duration_seconds{quantile="0.25"} 0go_gc_duration_seconds{quantile="0.5"} 0...

DCGM Exporter

用于采集 NVIDIA GPU 的数据,以 Docker 镜像运行:

docker run -d --restart=always --gpus all -p 9400:9400 nvidia/dcgm-exporter

查看数据:

$ curl localhost:9400/metrics# HELP DCGM_FI_DEV_SM_CLOCK SM clock frequency (in MHz).# TYPE DCGM_FI_DEV_SM_CLOCK gauge# HELP DCGM_FI_DEV_MEM_CLOCK Memory clock frequency (in MHz).# TYPE DCGM_FI_DEV_MEM_CLOCK gauge# HELP DCGM_FI_DEV_MEMORY_TEMP Memory temperature (in C)....

服务器

Prometheus

配置 ~/prometheus.yml

global:  scrape_interval: 15sscrape_configs:# Node Exporter- job_name: node  static_configs:  - targets: ['192.167.200.91:9100']# DCGM Exporter- job_name: dcgm  static_configs:  - targets: ['192.167.200.91:9400']

运行 Docker 镜像:

docker run -d --restart=always \-p 9090:9090 \-v ~/prometheus.yml:/etc/prometheus/prometheus.yml \prom/prometheus

Grafana

运行 Docker 镜像:

docker run -d --restart=always -p 3000:3000 grafana/grafana
