Example

Use case: Find the quickest latency per path

Suppose you want to identify which spans have the shortest duration.

Example data

{ "applicationName": "default", "duration": 4 },
{ "applicationName": "default", "duration": 25 },
{ "applicationName": "074157727657", "duration": 14 },
{ "applicationName": "074157727657", "duration": 90 },
{ "applicationName": "streaming-platform", "duration": 81 },
{ "applicationName": "web-app", "duration": 1000 },
{ "applicationName": "docs", "duration": 2000 },
{ "applicationName": "checkout", "duration": 4500 },
{ "applicationName": "checkout", "duration": 7000 },
{ "applicationName": "search", "duration": 3200 }

Example query

source spans
| bottom 10 $l.applicationName by min($m.duration)

Example output

applicationName	_min0
default	4
074157727657	14
streaming-platform	81
web-app	1000
docs	2000
