Trying to extract from similar events in log file using regex

[jd0323fhl]

I have two distinct events in an application log file: (see below). The events are multiline and seperated by a line of ------------. The fields are not in the same order between the two events. I would like to harmonize the events so that I can report on fields like Timestamp, Message, Category, etc.

I tried to use the automatic field extractor, but it could not read any field other than timestamp. I also attempted to use the following regex patterns, but the fields do not line up. I there a better single regex or a better method using the props.conf/transforms.conf to normalize this data.

Regex 1:
^\w*: (?<timestamp>.*)\s^\w*: (?<message>.*)\s\w*: (?<category>.*)\s\w*: (?<machine>.*)\s\w*\s\w*: (?<app_domain>.*)\s\w*\s\w*: (?<process_name>.*)\s\w*\s\w*:(?<thread_name>[^-]*$)

Event 1:

  Timestamp: 5/29/2018 8:10:46 AM
    Message: Debugging Logging Path: In HttpClientWrapper going to call HttpClientDI.GetAsync(requestUri) with ***"website URL here"***
    Category: Informational

    Process Name: c:\windows\system32\inetsrv\w3wp.exe
    Thread Name: 

    ----------------------------------------

Regex 2:

^\w*:(?<timestamp>[^\n\r]*)\s\w*:(?<message>.*)\n\w*:(?<category>.*)\n\w*:(?<priority>.*)\n\w*:(?<eventid>.*)\n\w*:(?<severity>.*)\n\w*:(?<title>[^\n\r]*)\n\w*:(?<machine>.*)\n\w*\W\w*:(?<app_domain>[^\n\r]*)\s\w*:(?<process_id>[^\n\r]*)\n\w*\W\w*:(?<process_name>[^\n\r]*)\n\w*\W\w*:(?<thread_name>[^\n\r]*)\n\w*\W\w*:(?<win32_threadid>[^\n\r]*)\n\w*\W\w*:(?<Extended_Properties>[^\n\r]*)$

I’d suggest to use props and transforms to set up individual extractions for each field. That way the order of the fields does not matter.

Might even work like this (not tested), which takes the part befor the first : as the key and the part after (until end of line) as the value and keeps matching that for each line of the event.

Props.conf

[yoursourcetype]
REPORT-extract-my-fields = extractmyfields

Transforms.conf

[extractmyfields]
REGEX = (?m)^([^:]+):\s+(.*)$
FORMAT = $1::$2
