is it possable to send post data using alert(http post)?

is it possible to send post data using alert(post)?
I made php result page , but there is no outputdata(ex. message, body..)

this is my test enviroment..

1. set up alert Rule Builder (chronograf Alerting Page)
http, Optional alter parameter : http://x.x.x.x/etc/mms2

2. mms2 php is
```

```

Reproduce the alert from Chronograf's Alert Rule Builder using the HTTP target and the /etc/mms2 PHP endpoint shown in the report. Check what request data the endpoint receives and whether the alert output contains the expected fields; done means the behavior is clearly confirmed and documented or a focused change is identified and validated.
