Documentation Grafana Agent Flow mode Get started Install Ansible

Install or uninstall Grafana Agent Flow using Ansible

You can use Ansible to install and manage Grafana Agent Flow on Linux hosts.

Before you begin

• These steps assume you already have a working Ansible setup and a pre-existing inventory.
• You can add the tasks below to any new or existing role.

Steps

To add Grafana Agent Flow to a host:

1. Create a file named grafana-agent.yml and add the following:

   yaml Copy

   - name: Install Grafana Agent Flow
     hosts: all
     become: true
     tasks:
       - name: Install Grafana Agent Flow
         ansible.builtin.include_role:
           name: grafana.grafana.grafana_agent
         vars:
           grafana_agent_mode: flow
           # Destination file name
           grafana_agent_config_filename: config.river
           # Local file to copy
           grafana_agent_provisioned_config_file:  "<path-to-config-file-on-localhost>"
           grafana_agent_flags_extra:
             server.http.listen-addr: '0.0.0.0:12345'

   Replace the following:

   • <path-to-config-file-on-localhost>: The path to the River configuration file on the Ansible Controller (Localhost).

2. Run the Ansible playbook. Open a terminal window and run the following command from the Ansible playbook directory.

   shell Copy

   ansible-playbook grafana-agent.yml

Validate

To verify that the Grafana Agent Flow service on the target machine is active and running, open a terminal window and run the following command:

shell Copy

$ sudo systemctl status grafana-agent.service

If the service is active and running, the output should look similar to this:

Copy

grafana-agent.service - Grafana Agent
  Loaded: loaded (/etc/systemd/system/grafana-agent.service; enabled; vendor preset: enabled)
  Active: active (running) since Wed 2022-07-20 09:56:15 UTC; 36s ago
Main PID: 3176 (agent-linux-amd)
  Tasks: 8 (limit: 515)
  Memory: 92.5M
    CPU: 380ms
  CGroup: /system.slice/grafana-agent.service
    └─3176 /usr/local/bin/agent-linux-amd64 --config.file=/etc/grafana-cloud/agent-config.yaml
