Integration with Ansible

• Ubuntu machine (local, virtual machine, or cloud VM)
• User with sudo privileges
• Basic familiarity with Ansible and Fluent Bit
• OpenObserve account (Cloud or Self-Hosted)
• Ansible Installed

1. Configure log output path in ansible.cfg:

[defaults]
log_path = /tmp/ansible_log_demo.txt

1. Create a sample playbook:

vi local_task.yml

2. Add the following contents:

---
- name: Ansible Local Task Demo
  hosts: localhost
  connection: local
  tasks:
    - name: Create a sample file
      ansible.builtin.file:
        path: /tmp/ansible_log_demo.txt
        state: touch

    - name: Write a message to the sample file
      ansible.builtin.copy:
        content: "This is a demo log entry from Ansible."
        dest: /tmp/ansible_log_demo.txt

3. Run the playbook:

ansible-playbook local_task.yml

After running, check /tmp/ansible_log_demo.txt to confirm logs are generated.

1. Install Fluent Bit using the official script:

curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh

For manual install or using package managers, refer to Fluent Bit Docs

2. Verify installation:

fluent-bit --version

1. Edit Fluent Bit config file:

sudo vi /etc/fluent-bit/fluent-bit.conf

2. Add the following configuration:

[SERVICE]
    Flush         5
    Daemon        Off
    Log_Level     info

[INPUT]
    Name          tail
    Path          /tmp/ansible_log_demo.txt
    Tag           ansible.demo
    Refresh_Interval 5

[OUTPUT]
    Name http
    Match *
    URI /api/<O2_ORG_NAME>/<O2_STREAM_NAME>/_json
    Host <O2_HOST>
    Port 443
    tls On
    Format json
    Json_date_key    _timestamp
    Json_date_format iso8601
    HTTP_User <O2_USER>
    HTTP_Passwd <O2_PASSWORD>
    compress gzip

Note - Replace <O2_ORG_NAME>, <O2_STREAM_NAME>, <O2_HOST>, <O2_USER>, and <O2_PASSWORD> with your OpenObserve values. - Example URI: /api/default/ansible/_json for the default org and ansible stream.

1. Start the Fluent Bit service:

sudo systemctl start fluent-bit
sudo systemctl enable fluent-bit

2. Check service status:

sudo systemctl status fluent-bit

Ensure there are no startup errors. Logs will now be tailed and sent to OpenObserve.

1. In your Openobserve instance, Go to Logs → select your log stream → Set time range → Click Run Query

   

• Ensure Fluent Bit is running: sudo systemctl status fluent-bit
• Double-check the HTTP config and authentication
• Use Fluent Bit in debug mode:

sudo fluent-bit -c /etc/fluent-bit/fluent-bit.conf -vv

• Confirm log_path is correctly set in ansible.cfg
• Use verbose flags (-v, -vv, -vvv) to produce more logs
• Confirm Ansible has permission to write to /tmp

• Make sure the path /tmp/ansible_log_demo.txt exists
• Tail the file manually to confirm updates:

tail -f /tmp/ansible_log_demo.txt

• Adjust Refresh_Interval or restart Fluent Bit if needed
