Available platform are:-

Usage

Either follow the choice A. or B. below to run Observium.

A. Manual Run Containers

  • Prepare working directory for docker containers, for example below.
  $ mkdir -p /home/docker/observium/{data,logs,rrd}
  • Run official MariaDB container
  $ docker run --name observiumdb \
    -v /home/docker/observium/data:/var/lib/mysql \
    -e MYSQL_ROOT_PASSWORD=passw0rd \
    -e MYSQL_USER=observium \
    -e MYSQL_PASSWORD=passw0rd \
    -e MYSQL_DATABASE=observium \
    -e TZ=$(cat /etc/timezone) \
    mariadb
  • Run this Observium container
  $ docker run --name observiumapp --link observiumdb:observiumdb \
    -v /home/docker/observium/logs:/opt/observium/logs \
    -v /home/docker/observium/rrd:/opt/observium/rrd \
    -e OBSERVIUM_ADMIN_USER=admin \
    -e OBSERVIUM_ADMIN_PASS=passw0rd \
    -e OBSERVIUM_DB_HOST=observiumdb \
    -e OBSERVIUM_DB_USER=observium \
    -e OBSERVIUM_DB_PASS=passw0rd \
    -e OBSERVIUM_DB_NAME=observium \
    -e OBSERVIUM_BASE_URL=http://yourserver.yourdomain:8080 \
    -e TZ=Asia/Bangkok
    -p 8080:80
    mbixtech/observium

Note:

  • You must replace passwords specified in environment parameters of both containers with your secure passwords instead.
  • OBSERVIUM_BASE_URL supports AMD64 container only (plan to support ARM32v7 soon).

B. Use Docker Composer

  • Follow instuctions below to create extra working directory of docker containers (You can change /home/docker directory to your desired directory).
  $ cd /home/docker
  $ git clone https://github.com/somsakc/docker-observium.git observium
  $ cd observium
  $ mkdir data logs mysql

Note: You do not need to clone whole git repository. You can download docker-compose.yml file and .env file file. Then, place both files into e.g. /home/docker/observium directory mentioned above.

  • Change some environments to your appropreate values in docker-compose.yml file, e.g. OBSERVIUM_ADMIN_USER, OBSERVIUM_ADMIN_PASS.

  • Force pulling the latest observium image from docker hub web site. It is to ensure that you will get the latest one.

  $ docker-compose pull
  • Run both database and observium containers.
  $ docker-compose up

  $ docker-compose exec app /opt/observium/add_device.php <hostname> <community> v2c
  $ docker-compose exec app /opt/observium/discovery.php -h all
  $ docker-compose exec app /opt/observium/poller.php -h all

TODOs

I have a lot of plan to enhance this project. However, my work is priority to focus first. I hope I will have more time to do it.

  • Enhance more on Kubernetes platform, for both AMD64 and ARM64 (Pi).
  • Enhance more with secure TLS to Observium GUI.
  • Secure more container image.
  • Integrate rsyslog [2022/Q3]
