Prometheus + Grafana 快速上手,監控主機的 CPU, GPU, MEM, IO 等狀態。

前提

使用者端

Node Exporter

用於採集 UNIX 核心主機的資料,這裡下載並解壓:

wget https://github.com/prometheus/node_exporter/releases/download/v1.1.2/node_exporter-1.1.2.linux-amd64.tar.gz
tar xvfz node_exporter-1.1.2.linux-amd64.tar.gz
cd node_exporter-1.1.2.linux-amd64
nohup ./node_exporter &

檢視資料:

$ 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 summary
go_gc_duration_seconds{quantile="0"} 0
go_gc_duration_seconds{quantile="0.25"} 0
go_gc_duration_seconds{quantile="0.5"} 0
...

DCGM Exporter

用於採集 NVIDIA GPU 的資料,以 Docker 映象執行:

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

檢視資料:

$ 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).
...

伺服器

Prometheus

設定 ~/prometheus.yml

global:
  scrape_interval: 15s

scrape_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']

執行 Docker 映象:

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

存取 http://localhost:9090/

存取 http://localhost:9090/targets

Grafana

執行 Docker 映象:

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

存取 http://localhost:3000/
