For the reviewers sake, this is what the code looked like before I made it JSON.
- script:
lang: painless
source: >-
def t = ctx.suricata?.eve?.event_type;
if (t == "stats") {
ctx['event']['kind'] = "metric";
} else if (t == "alert") {
ctx['event']['kind'] = "alert";
ctx['event']['category'] = "network_traffic";
} else {
ctx['event']['kind'] = "event";
ctx['event']['category'] = "network_traffic";
}

@webmat This is metric now. 👍
Set `event.category: network_traffic`. And conditionally set event.kind based on the `event_type` field. Use `alert` for suricata alerts and `event` for everything else. Also skip geoip if the event has already been enriched (like if the data went through Logstash first).
