try to use heartbeat to ping thrift interface(call ping method , receive string "pong")
i ping through tcp and need to send a binary data as below:
check.send: "\x00\x00\x00\x10\x80\x01\x00\x01\x00\x00\x00\x04\x70\x69\x6e\x67\x00\x00\x00\x01\x00"
check.receive: "\x00\x00\x00\x1c\x80\x01\x00\x02\x00\x00\x00\x04\x70\x69\x6e\x67\x00\x00\x00\x01\x0b\x00\x00\x00\x00\x00\x04\x50\x4f\x4e\x47\x00"
but "\x80" seems to be overflow ,
send data would become：
\x00\x00\x00\x10 \x2c \x80\x01\x00\x01\x00\x00\x00\x04\x70\x69\x6e\x67\x00\x00\x00\x01\x00
additional "\x2c"

1. Can you try to put the string with single quotes? like `check.send: '\x00\x00\x00\x10\x80\x01\x00\x01\x00\x00\x00\x04\x70\x69\x6e\x67\x00\x00\x00\x01\x00'`. If double quotes are used, the YAML parser interprets strings itself. Using `'` the string is passed to heartbeat as is.
2. Feel free to open an [enhancement request](https://github.com/elastic/beats/issues) for an heartbeat thrift monitor. Instead of messing with the `tcp` monitor, it should be as easy as using the `thrift` monitor type.

i have try use the **'**
it's not ok too, yaml would not handle the backslash，
it just treat '\x80' as '\', 'x' , '8', '0' 4 char.
i will open the request later
