For example, if you want to use the source events risk score in Post pix and tell us how about your Yikerz game playing experiences! If you set Count to limit the results by process.name >= 2, an alert will only be generated for source/destination IP pairs that appear with at least 2 unique process names across all events. So please help me with this if you can. 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.
