Documentation Grafana Alloy Set up Install Ansible

Install or uninstall Grafana Alloy using Ansible

You can use the Grafana Ansible Collection to install and manage Alloy 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 Alloy to a host:

1. Create a file named alloy.yml and add the following:

   yaml Copy

   - name: Install Alloy
     hosts: all
     become: true
   
     tasks:
       - name: Install Alloy
         ansible.builtin.include_role:
           name: grafana.grafana.alloy
         vars:
           alloy_config: |
             prometheus.scrape "default" {
               targets = [{"__address__" = "localhost:12345"}]
               forward_to = [prometheus.remote_write.prom.receiver]
             }
             prometheus.remote_write "prom" {
               endpoint {
                   url = "<YOUR_PROMETHEUS_PUSH_ENDPOINT>"
               }
             }

   This snippet has a sample configuration to collect and send Alloy metrics to Prometheus

   Replace the following:

   • <YOUR_PROMETHEUS_PUSH_ENDPOINT>: The Remote write endpoint of your Prometheus Instance.

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

   shell Copy

   ansible-playbook alloy.yml

Validate

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

shell Copy

$ sudo systemctl status alloy.service

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

Copy

alloy.service - Grafana Alloy
  Loaded: loaded (/etc/systemd/system/alloy.service; enabled; vendor preset: enabled)
  Active: active (running) since Wed 2022-07-20 09:56:15 UTC; 36s ago
