Configuring Grafana Agent Flow

Configuring the Grafana Agent Flow service

To customize the Grafana Agent Flow service on macOS, perform the following steps:

Run the following command in a terminal:
```
brew edit grafana-agent-flow
```
This will open the Grafana Agent Flow Homebrew Formula in an editor.
Modify the service section as desired to change things such as:
- The configuration file used by Grafana Agent Flow.
- Flags passed to the Grafana Agent Flow binary.
- Location of log files.
When done, save the resulting formula file.
Reinstall the Grafana Agent Flow Formula by running the following command in a terminal:
```
brew reinstall grafana-agent-flow
```
Restart the Grafana Agent Flow service by running the command in a terminal:
```
brew services restart grafana-agent-flow
```

Exposing 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][UI].

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

Follow Configuring the Grafana Agent Flow service to edit command line flags passed to Grafana Agent Flow, including the following customizations:
1. Modify the line inside the service block containing --server.http.listen-addr=127.0.0.1:12345, replacing 127.0.0.1 with the 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 127.0.0.1 with 0.0.0.0.

Viewing Grafana Agent Flow logs

By default, logs are written to $(brew --prefix)/var/log/grafana-agent.log and $(brew --prefix)/var/log/grafana-agent-flow.err.log.

If you followed Configuring the Grafana Agent Flow service and changed the path where logs are written, refer to your current copy of the Grafana Agent Flow formula to locate log files.
