Supervision tool#

prometheus#

Tendermint also supports the use of prometheus metrics. This function is enabled by setting prometheus=true in config/config.toml. Through setting prometheus_listen_addr, the default supervision address :26660 is changed. The default status is set as enable on OKTC’s testnet.

Metrics available on OKTC#

Supervision tool#

Create monitor.yml

version: '2'
services:
  prometheus:
    image: prom/prometheus
    container_name: prometheus
    hostname: prometheus
    user: "root"
    volumes:
      - ./prometheus_config.yml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"

  grafana:
    image: grafana/grafana
    container_name: grafana
    hostname: grafana
    user: "root"
    ports:
      - '3000:3000'

Create prometheus_config.yml in the same directory

global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

scrape_configs:
  - job_name: 'node'
    static_configs:
      - targets: ['localhost:26660']
        labels:
          instance: fullnode

Enable prometheus and grafana in the same directory

docker-compose -f monitor.yml up -d

After enabling the above, you can see the information on prometheus via http://localhost:9090. You can configure a dashboard (template id: 7044) suitable for oktc via http://localhost:3000(the default account name and password are both admin) and adjust it by customizing the names of metrics.

Note: Users can also enable prometheus and grafana through other methods.
