I don't know where that "Log event" UI you showed in the description comes from, but I just wanted to comment here that I usually use the "Log Patterns" one: https://one.newrelic.com/logger/log-patterns?account=63767&duration=604800000&state=bfbf16ba-d4d1-b557-f420-a41585d0530b and has been being really useful to me.

@humitos nice, that's a good dashboard. Mine was just a custom query that I futzed with in NR -- I figured it was built in, but couldn't find it quickly :)
