CloudWatch Log Stream Path

Match AWS CloudWatch log group / stream paths like `/aws/lambda/my-function` or `/aws/ecs/cluster-name`.

Available in

JavaScript / ECMAScript code

jsJavaScript

const re = new RegExp("\\/aws\\/(?:lambda|ecs|eks|apigateway|codebuild|stepfunctions|rds|cloudtrail)\\/[\\w\\-.\\/]+", "g");
const input = "Group: /aws/lambda/api-gateway-handler";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

Python (re) code

pyPython

import re

pattern = re.compile(r"\/aws\/(?:lambda|ecs|eks|apigateway|codebuild|stepfunctions|rds|cloudtrail)\/[\w\-.\/]+")
input_text = "Group: /aws/lambda/api-gateway-handler"
for m in pattern.finditer(input_text):
    print(m.group(0))

Stdlib `re` module — no third-party dependency. Works on Python 3.6+.

Go (RE2) code

goGo

package main

import (
	"fmt"
	"regexp"
)

func main() {
	re := regexp.MustCompile(`\/aws\/(?:lambda|ecs|eks|apigateway|codebuild|stepfunctions|rds|cloudtrail)\/[\w\-.\/]+`)
	input := `Group: /aws/lambda/api-gateway-handler`
	for _, match := range re.FindAllString(input, -1) {
		fmt.Println(match)
	}
}

Uses `regexp.MustCompile` (panics on bad patterns at startup) and `FindAllString` for all matches.

Pattern

regexengine-agnostic

\/aws\/(?:lambda|ecs|eks|apigateway|codebuild|stepfunctions|rds|cloudtrail)\/[\w\-.\/]+   (flags: g)

How it works

Anchors on the AWS-managed log group prefix `/aws/`, then a known service name from the alternation, then the resource path. The character class [\w\-.\/] allows word chars, hyphens, dots, and slashes — covering nested paths like `/aws/lambda/prod-handler/2024/01/15`.
