write splunk query to list all user agents in aws elb logs in javascript

You can use the following Splunk query to list all user agents in AWS ELB logs in JavaScript:

index.tsx
<your_search>
| spath user_agent
| search user_agent!=""
| table user_agent
76 chars
5 lines

This query searches for the user_agent field in ELB logs (which contains user agent information), filters out any empty values, and returns a table of unique user_agent values. In order to specify that the logs are written in JavaScript, you need to include the appropriate sourcetype in your search. Example: sourcetype="aws:elb:accesslogs".

Hope this helps!
