## How do monitors work?

Using monitors is very straightforward: just tell us when a cron job has finished, and we'll mark it as such. If we haven't received a pulse in time, we assume it's down, and we'll let you know.

To send out a pulse, add an HTTP request at the end of your cron job. The URL you need to call, can be found on the page of your monitor. It should look like this:

`https://cronly.app/api/monitors/pulse/a4f28bca-df99-47bf-a435-c6d8d2c948fd`

### Examples

{% hint style="info" %}
**Tip:** These examples are very basic. There are other ways available, for example with open source packages. We'll be adding more examples soon.
{% endhint %}

```bash
curl "https://api.cronly.app/1.1/cron/pulse?token={token}"
```

```php
<?php
file_get_contents("https://api.cronly.app/1.1/cron/pulse?token={token}");
```

```python
import urllib2
try:
    urllib2.urlopen("https://api.cronly.app/1.1/cron/pulse?token={token}")
except Exception:
    pass
```

```typescript
var https = require('https');
https.get("https://api.cronly.app/1.1/cron/pulse?token={token}");
```
