Let it sync - Geth uses a fast sync mode by default. It may take anywhere between a few hours and a couple of days.
>**Note:** It is safe to run Nimbus and start validating even if Geth hasn't fully synced yet.

You'll know Geth has finished syncing, when you start seeing logs that look like the following:

In this page we'll cover how to use Grafana and Prometheus to help you visualise important real-time metrics concerning your validator and/or beacon node.
@ -13,7 +13,7 @@ Grafana is a tool for beautiful dashboard monitoring that works well with Promet
The easiest way to see metrics concerning your validator / node is to build the beacon node with the `NIMFLAGS="-d:insecure"` flag. For example, to enable metrics for a `medalla` validator, run:
```
make NIMFLAGS="-d:insecure" medalla-build
make NIMFLAGS="-d:insecure" nimbus_beacon_node
```
> **Note:** Metrics are not included in the binary by default. The `NIMFLAGS="-d:insecure"` is needed because we consider the HTTP server that needs to start to serve the metrics to be insecure (without this flag it won't launch properly). As such, we recommend you make sure port 8008 is protected.
