How to calculate Max, Min, Avg for duration of a transaction?

[amunag439]

I'm calculating the time difference between two events by using Transaction and Duration. Below is the query that I used to get the duration between two events Model and Response

host=* sourcetype=** source="*/example.log" "Model*" OR "Response*"
| transaction traceId startswith="Model" endswith="Response" | eval dur=duration
| eval time_taken=tostring(dur,"duration")  | table traceId time_taken _time

And the result would be similar to

traceId          |      time_take      | _time
trace_1681692777 |   00:00:0.451        | 2019-07-03 15:52:02.537
trace_1681692779 |   00:00:1.921        | 2019-07-03 15:55:00.129
trace_1681692780 |   00:00:3.981        | 2019-07-03 15:59:01.754

Using the above data, I want to get the max, min and avg time_taken values. I tried using stats min(dur) as min, etc and eval but was not successful. How do I achieve this?

Like this:

index=YouShouldAlwaysSpecifyAnIndex AND sourcetype=AndSourcetypeToo AND host=* AND source="*/example.log" AND ("Model*" OR "Response*")
| transaction traceId startswith="Model" endswith="Response"
| eventstats min(duration) As min_dur max(duration) AS max_dur avg(duration) AS avg_dur
| rename duration AS time_taken
| fieldformat time_taken = tostring(duration,"duration")
| table traceId time_taken _time *_dur

Works like a charm. Thank you
