# Up/Down Monitoring

> ProxyLink checks your services every minute and alerts you when something goes down.

ProxyLink monitors any proxy link and sends alerts when the service goes down or comes back up.

## Enable monitoring

Edit a proxy link and toggle **Monitoring** on. Choose the check method:

| Method          | Use case                                                 |
| --------------- | -------------------------------------------------------- |
| **TCP**         | Any TCP service — checks if the port accepts connections |
| **ICMP (ping)** | Network devices that respond to ping                     |

## Alert channels

Configure alert destinations on the proxy link:

* **Email** — sent to your account email
* **Slack** — paste a Slack webhook URL
* **Microsoft Teams** — paste a Teams webhook URL
* **Custom webhook** — any URL that accepts POST requests

## Alert format (webhook)

```json theme={null}
{
  "status": "down",
  "label": "Hotel Anna — NVR",
  "target": "192.168.20.10:80",
  "time": "2026-05-11 20:00:00 EEST"
}
```

## Spam prevention

A 30-minute cooldown prevents repeated alerts for the same service. You get one alert when it goes down, and one when it recovers.

## NOC dashboard

All monitored services appear on the NOC dashboard with live status.
