    sudo systemctl reload grafana-agent-flow

To change the configuration file used by the service, perform the following steps:

  1. Edit the environment file for the service:

    • Debian or Ubuntu: edit /etc/default/grafana-agent-flow
    • RHEL/Fedora or SUSE/openSUSE: edit /etc/sysconfig/grafana-agent-flow
  2. Change the contents of the CONFIG_FILE environment variable to point to the new configuration file to use.

  3. Restart the Grafana Agent Flow service:

    shell
    sudo systemctl restart grafana-agent-flow

Pass additional command-line flags

By default, the Grafana Agent Flow service launches with the run command, passing the following flags:

  • --storage.path=/var/lib/grafana-agent-flow

To pass additional command-line flags to the Grafana Agent Flow binary, perform the following steps:

  1. Edit the environment file for the service:

    • Debian-based systems: edit /etc/default/grafana-agent-flow
    • RedHat or SUSE-based systems: edit /etc/sysconfig/grafana-agent-flow
  2. Change the contents of the CUSTOM_ARGS environment variable to specify command-line flags to pass.

  3. Restart the Grafana Agent Flow service:

    shell
    sudo systemctl restart grafana-agent-flow

To see the list of valid command-line flags that can be passed to the service, refer to the documentation for the run command.

Expose the UI to other machines

By default, Grafana Agent Flow listens on the local network for its HTTP server. This prevents other machines on the network from being able to access the UI for debugging.

To expose the UI to other machines, complete the following steps:

  1. Follow Pass additional command-line flags to edit command line flags passed to Grafana Agent Flow, including the following customizations:

    1. Add the following command line argument to CUSTOM_ARGS:

      shell
      --server.http.listen-addr=LISTEN_ADDR:12345

      Replace LISTEN_ADDR with an address which other machines on the network have access to, like the network IP address of the machine Grafana Agent Flow is running on.

      To listen on all interfaces, replace LISTEN_ADDR with 0.0.0.0.
