need to extract multiple values for a field in a custom event

[ssyed2009]

The whole event is coming in as below. Need eventtype to extract "event_type={type}" and size to extract all the values in size
{"event_type":"event_type=adsad","size":"128844"}
{"event_type":"event_type=dsadsa","size":"388719"}
{"event_type":"event_type=blue","size":"1841504"}
{"event_type":"event_type=bluecoat","size":"221712725587"}
{"event_type":"event_type=casmdsad","size":"12356947232"}
{"event_type":"event_type=cisco-ddddd","size":"1553892585172"}
{"event_type":"event_type=cisco-edsd","size":"42949321020"}
{"event_type":"event_type=cyberark-dsds","size":"77274472"}
{"event_type":"TOTAL","size":"4314601844158"}

please try this one:
"event_type=(?\w[a-zA-Z-]+)\D+(?\d*)

Sorry I pasted the wrong regex
"event_type=(?\w[a-zA-Z-]+)\D+(?\d*)
