Download and install

Possible options:

1) Download precompiled versions from https://prometheus.io/download/

2) Hard way, build everything yourself

$ mkdir -p $GOPATH/src/github.com/prometheus
$ cd $GOPATH/src/github.com/prometheus
$ git clone https://github.com/prometheus/prometheus.git
$ cd prometheus
$ make build
$ mkdir -p $GOPATH/src/github.com/prometheus
$ cd $GOPATH/src/github.com/prometheus
$ git clone https://github.com/prometheus/alertmanager.git
$ cd alertmanager
$ make build
$ go get github.com/prometheus/node_exporter
$ cd ${GOPATH-$HOME/go}/src/github.com/prometheus/node_exporter
$ make
$ go get github.com/mindprince/nvidia_gpu_prometheus_exporter
$ cd ${GOPATH-$HOME/go}/src/github.com/mindprince/nvidia_gpu_prometheus_exporter
$ make

Yaml files

1. prometheus.yml

prometheus config file, example that i use

global:
  # Set the scrape interval to every 15 seconds
  scrape_interval: 15s # Set the scrape interval to every 15 seconds
  # Evaluate rules every 15 seconds
  evaluation_interval: 15s

# Alertmanager configuration
alerting:
  alertmanagers:
  - scheme: http
    static_configs:
    - targets:
    # Alertmanager port
      - "localhost:9093"

# Rules yaml file (additional metrics + alert rules)
rule_files:
  - "alert_rules.yml"

# A scrape configuration
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  # Where to listen to additional metric exporters
  # GPU metrics (Nvidia_gpu_prometheus_exporter)
  - job_name: 'gpu'
    static_configs:
    - targets: ['localhost:9445']

  # Node metrics (Node_exporter)
  - job_name: 'node'
    static_configs:
    - targets: ['localhost:9100']

2. alertmanager.yml

alertmanager config file, example


global:
  smtp_smarthost: smtp.gmail.com:587
  smtp_from: SOME_EMAIL
  smtp_auth_username: USERNAME
  smtp_auth_password: PASSWORD
  smtp_auth_identity: IDENTITY(EMAIL)

route:
  group_by: [Alertname]
  receiver: email-me
  # How long to wait before sending a notification again if it has already
  # been sent successfully for an alert
  repeat_interval: 2h

receivers:
- name: email-me
  email_configs:
  - to: aveysov@gmail.com, dvoronin322@gmail.com

3. alert_rules.yml

metric rules for alertmanager (when to fire alarm), example

groups:
- name: box_2_stats
  rules:
  - alert: GPU_HIGH_TEMPERATURE
    # Fire when average gpu temperature for past 2 minutes more than 90 celsius
    expr: avg_over_time(nvidia_gpu_temperature_celsius[2m]) > 90
    for: 30s
    annotations:
        description: "{{ $value }} celsius mean GPU temperature for past 2 minutes!"

  - alert: CPU_HIGH_TEMPERATURE
   # Fire when average cpu temperature for past 2 minutes more than 90 celsius
    expr: avg_over_time(node_hwmon_temp_celsius[2m]) > 75
    for: 30s
    annotations:
        description: "{{ $value }} celsius mean CPU temperature for past 2 minutes!"

  - alert: RAM
   # Fire when available RAM < 500 MB
    expr: round((node_memory_MemAvailable_bytes) / 1024 / 1024) < 500
    for: 1m
    annotations:
        description: "Only {{ $value }} MB RAM available!"

  - alert: NVME_MEM
   # Alert when less than 10 GB available on NVME disk
    expr: round(node_filesystem_avail_bytes{mountpoint="/mnt/nvme"} / 1024 / 1024 / 1024) < 10
    for: 5m
    annotations:
        description: "{{ $value }} space available on /mnt/nvme!"
   
   - alert: SDE1_MEM
    expr: round(node_filesystem_avail_bytes{device="/dev/sde1"} / 1024 / 1024 / 1024) < 5
    for: 5m
    annotations:
        description: "{{ $value }} space available on SDE!!"
        
   - alert: SDE1_MEM
    expr: round(node_filesystem_avail_bytes{device="/dev/sde1"} / 1024 / 1024 / 1024) < 5
    for: 5m
    annotations:
        description: "{{ $value }} space available on /mnt/nvme!"

  - alert: MD
   # Fire when disk is not available
    expr: (node_md_disks_active - node_md_disks) > 0
    for: 10m
    annotations:
        description: "Something wrong with disk"

  - alert: IOWAIT
   # Fire when iowait > 0.85 per second for past 5 minutes
    expr: rate(node_cpu_seconds_total{mode="iowait"}[5m]) > 0.85
    for: 5m
    annotations:
        description: "High iowait value! ({{ $value }} mean for past five minutes)"

Run everything

I use this .sh script to run everything at once

#!/bin/bash
cd node_exporter-0.18.1.linux-amd64/ && ./node_exporter \
& nvidia-docker run -p 9445:9445 -ti mindprince/nvidia_gpu_prometheus_exporter:0.1 \
& cd alertmanager-0.17.0.linux-amd64/ && ./alertmanager --config.file=alertmanager.yml \
& cd prometheus-2.10.0.linux-amd64/ && ./prometheus --config.file=./prometheus.yml --web.listen-address="0.0.0.0:9092" \
