How to: Monitoring an endpoint using ICMP
By prefixing `endpoints[].url` with `icmp://`, you can monitor endpoints at a very basic level using ICMP, or more
commonly known as "ping" or "echo":
```yaml
endpoints:
  - name: ping-example
    url: "icmp://example.com"
    conditions:
      - "[CONNECTED] == true"
```

Only the placeholders `[CONNECTED]`, `[IP]` and `[RESPONSE_TIME]` are supported for endpoints of type ICMP.
You can specify a domain prefixed by `icmp://`, or an IP address prefixed by `icmp://`.

If you run Gatus on Linux, please read the Linux section on [https://github.com/prometheus-community/pro-bing#linux]
if you encounter any problems.

Prior to `v5.31.0`, some environment setups required adding `CAP_NET_RAW` capabilities to allow pings to work.
As of `v5.31.0`, this is no longer necessary, and ICMP checks will work with unprivileged pings unless running as root. See #1346 for details.
