IMPORTANT: The use of magnets near or around computers, TV screens, tape recorders, CDs, watches, etc. One note of caution that applies to watcher or detection engine rules with nested aggregations is that the number aggregation buckets across all (source.ip x destination.ip) combinations could have very high cardinality in a large environment, so you might want to ensure that the rule operates on only a single comprehensive set of network data, and/or include filters in the original query where appropriate. I'm sure I'm overlooking something, but any help would be appreciated. Steps to reproduce the behavior: The condition ctx.results[0].aggregations.by_src_ip.buckets[i].by_target_ip.buckets[j].unique_port_count.value > 1 is just to make sure a match would accure.
