Why is stats avg(response_time) not working after extracting response_time?

I am a beginner. Why is stats avg(response_time) not working after extracting response_time?

index="testing1" source="web_access_log_project2.txt" | erex response_time examples="7ms, 0ms, 17ms, 67ms, 77ms, 39ms " | stats count, avg(response_time)

Below is the sample event:

127.0.0.1 - - [17/Mar/2023:17:59:13.798 -0400] "HEAD /favicon.ico HTTP/1.1" 303 124 "" "Splunk/9.0.4 (Windows Server 10 Professional with Media Center Edition; arch=x64)" - 6414e2b1cc1a8e6558ec8 7ms

Hi @Tioluwani-Ada

The "ms" in the response time field makes it a string so it needs to be stripped to make is a integer that can then have mathematical calculations done on it.

The following should meet your needs...

index="testing1" source="web_access_log_project2.txt" | rex "(?<response_time>\d+)ms$" ``` strip out response time in ms ``` | stats count avg(response_time) AS avg_response_time

Hope this helps
