go-awslogs

Introduction

Inspired by https://github.com/jorgebastida/awslogs.

go-awslogs is a command line utility for easier access of AWS CloudWatch logs.

TL;DR:

# Show all log groups
go-awslogs groups

# Show all log streams of a group
go-awslogs streams <group_name>

# Watch log stream
go-awslogs get <group_name> --watch

# Show help
go-awslogs help

Usage

Get Log Groups

go-awslogs groups

# Filter the result with group name prefix
go-awslogs groups --prefix <prefix>

Get Log Streams

go-awslogs streams <group_name>

Get Log Events

go-awslogs get <group_name> [stream_name1 [, stream_name2 [,...]]]

Additional arguments:

--watch, -w: Watch the log streams (like tail -f)

--start, -s: Filter the log events by starting timestamp (Show log events after the timestamp)

--end, -e: Filter the log events by end timestamp (Show log events before the timestamp)

--stream-name, -N: Print the stream name as prefix of each line

Time Parsing

For the timestamp arguments like --start and --end, go-awslogs accepts 3 forms of time string:

Relative Time: 5min ago, 1.5hours ago, etc. (ago can be omitted)

RFC3339: 2020-07-23T15:23:35Z or 2020-07-23T08:23:35-07:00

Human: 01/02/2006 15:04:05 -07:00

AWS Profile

go-awslogs internally uses aws-sdk-go-v2. It loads the default AWS profile without any setting.

A different AWS profile can be used by setting an environment variable:

AWS_PROFILE=my_other_profile go-awslogs groups

Also, you can set environment variables directly for AWS_SECRET_ACCESS_KEY, AWS_ACCESS_KEY and AWS_REGION etc.

Build

Mac

Clone this repository and run ./build script. It will compile the project and generate binaries for both Mac and Linux.
