Reading Gravity Zone Syslog

I am writing a Python program to read Gravity Zone syslogs and wondering about the log structure. I understand that Gravity Zone can produce different events (Malware detection events, phishing/fraud events, etc.)

I am trying to understand if those events have some sort of header that identifies the event type or are these events placed into different logs?

For example, here is a log snippet (from the Gravity Zone manual), but other than read the raw JSON, how does someone know that this is a malware event? Is there a header? Is there a "type_of_event" field somewhere? Reading the raw JSCON to see if the word "malware" appears as a field seems sub-optimal, so just wondering if I am missing something?

Here is the sample JSON - yes I can kind of figure out that the this is a malware event due to the malware_type field, but I would rather say "If event_type = 'malware_event' - but I don't see anywhere in the syslog samples where that is possible.

If anyone has a tool they are using to read these logs, would love to hear your approach...thank you in advance.
