Hi all,

I am new to haproxy, but pretty happy with it so far. I was wondering if there is any option to run scripts in case of failover.

So far I only found options to email and log. But I would rather run a script to send a SMS or run some re-configuration.

Is there any support for this? Planned?

Thanks

My research only came up with two sub-optimal solutions:

I have to use a SMTP-HTTP gateway to trigger events with other services.

> **[HAProxy Alerts with WebHooks](https://el-tramo.be/blog/haproxy-webhook-alerts/)**
>
> I want to be notified immediately when one of the backend servers behind my HAProxy instance goes down. HAProxy offers alerting functionality, but only via SMTP: when a backend goes down it sends an email to a list of recipients via an SMTP server...

Or trigger something by replacing the checks itself with my own script.

Why not have something like

```
script-alert <script> 
script-alert level alert

```

or

```
webhook-alert <uri> 
webhook-alert level alert
```
