openobserve - observability

February 5, 2025

using openobserve

openobserve is a obervability server (backend for metrics, traces and logs) for free.

how it works

send windows event logs, metrics and other observability data to an opentelemetry backend using a opentelemetry collector.

prepare your backend

  • start the server with an admin account

  • add more users (unfortunately not service accounts)

docker compose
networks:
  loki:

volumes:
  o2-data:
    labels:
      org.manathome.description: "openobserve data storage"

services:
  openobserve:
    image: public.ecr.aws/zinclabs/openobserve:latest
    container_name: openobserve
    restart: unless-stopped
    environment:
      ZO_ROOT_USER_EMAIL: "man.from.home@gmail.com"
      ZO_ROOT_USER_PASSWORD: "(use your own)"
    ports:
      - "5080:5080"
    volumes:
      - o2-data:/data
    networks:
      - loki

  openobserve-init:
    image: curlimages/curl:latest
    container_name: openobserve-init
    entrypoint: >
      /bin/sh -c "
      echo 'Waiting for openobserve...';

      until curl -s http://openobserve:5080/healthz; do
        echo 'Waiting for OpenObserve to be ready...';
        sleep 2;
      done;

      echo 'Create Account...';

      curl -X POST http://openobserve:5080/api/default/users \
      -H 'Content-Type: application/json' \
      -H 'authorization: Basic (encoded from above)' \
      -d '{\"email\":\"o2-log-account@gmail.com\",\"role\":\"admin\",\"password\":\"(another-pw-choose-yourself)\"}';

      echo '..';
      echo 'account setup completed.'"
    restart: "no"
    depends_on:
      - openobserve
    networks:
      - loki

caveats

I could not create service accounts (needed for agents authentication) on startup or via api. So I could not ramp up a fresh environment via IaC as intended.
