Hey Folks, So I'm looking to pull EVENT.DURATION out of the Logstash IIS preloaded filter. That's all in place and pulling fine. ![image](https://us1.discourse-cdn.com/elastic/original/3X/6/4/645a1e8dfa6a35b40eccab6bfb012f444ab70b43.png) However, you'll notice that it's pulling as an int, which is exactly what I want. The weird part is, I can't seem to pull ANYTHING when I ask to grab log entries below a certain level (remove the downtime pieces) When I ask for event.duration \< 4000 I get exclusively 0.0's back. When I add "And event.duration \> 0.0" I get nothing back at all. ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/1/c1a94dd274759097b6f0a9654364f11f4415374c.png) Any Idea's what's happening here? ---

Hi @ELKNub, could you share the mapping for your index (specifically for the event.duration field)? ---

Uh.... Maybe? Not sure I know how to do that.... My username checks out. wait yes! ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/d/5dcd446d8f5cfcd6fdd8c40e6bd89b9b692f2649.png) ---

Figured it out! Thanks for pointing me in the right place. When I hit the edit button next to the mapping, it has an "input" and "output" section. The "Input" was set to nanoseconds, while the "Output" was set to milliseconds. While I didn't want to change either of these for fear of breaking shit, I DID realize that if I want to see counts under 10,000 ms (as they are displaying) I ACTUALLY need to add 6 zero's for converting to nanosecnds. So the filter "event.duration \> 10000000000" works exactly how I need it. Thanks! ---

Glad you got it to work, good job on figuring it out! It’s a little confusing the table is applying the format while the query isn’t, definitely good feedback ---
