# Saw
`saw` is a multi-purpose tool for AWS CloudWatch Logs
[](https://goreportcard.com/report/github.com/TylerBrock/saw)
## Features
- Colorized output that can be formatted in various ways
- `--expand` Explode JSON objects using indenting
- `--rawString` Print JSON strings instead of escaping ("\n", ...)
- `--invert` Invert white colors to black for light color schemes
- `--raw`, or `--pretty`, for `watch` and `get` commands respectively, toggles display of the timestamp and stream name prefix.
- Filter logs using CloudWatch patterns
- `--filter foo` Filter logs for the text "foo"
- Watch aggregated interleaved streams across a log group
- `saw watch production` Stream logs from production log group
- `saw watch production --prefix api` Stream logs from production log group with prefix "api"
## Usage
- Basic
```sh
# Get list of log groups
saw groups
# Get list of streams for production log group
saw streams production
```
- Watch
```sh
# Watch production log group
saw watch production
# Watch production log group streams for api
saw watch production --prefix api
# Watch production log group streams for api and filter for "error"
saw watch production --prefix api --filter error
```
- Get
```sh
# Get production log group for the last 2 hours
saw get production --start -2h
# Get production log group for the last 2 hours and filter for "error"
saw get production --start -2h --filter error
# Get production log group for api between 26th June 2018 and 28th June 2018
saw get production --prefix api --start 2018-06-26 --stop 2018-06-28
```
### Profile and Region Support
By default Saw uses the region and credentials in your default profile. You can override these to your liking using the command line flags:
```sh
# Use personal profile
saw groups --profile personal
# Use us-west-1 region
saw groups --region us-west-1
```
## Installation
### Run from Docker
```sh
docker run --rm -it -v ~/.aws:$HOME/.aws tbrock/saw
```
### Mac OS X
```sh
brew tap TylerBrock/saw
brew install saw
```
### Linux
#### Arch Linux (source)
```sh
# Using yay
yay saw
# Using makepkg
git clone https://aur.archlinux.org/saw.git
cd saw
makepkg -sri
```
#### Red Hat Based Distributions (Fedora/RHEL/CentOS/Amazon Linux)
```sh
rpm -i
```
#### Debian Based Distributions (Debian/Ubuntu)
```sh
wget
sudo dpkg -i
```
### Manual Install/Update
- [Install go](https://golang.org/doc/install)
- Configure your `GOPATH` and add `$GOPATH/bin` to your path
- Run `go install github.com/TylerBrock/saw@latest`
#### Windows Specifics
- Add %GOPATH%/bin to your path (optional)
- Run from gopath/bin (If not in your path)
```DOS .bat
cd %GOPATH%/bin
saw ...
```
Alternatively you can hard code these in your shell's init scripts (bashrc, zshrc, etc...):
```sh
# Export profile and region that override the default
export AWS_PROFILE='work_profile'
export AWS_REGION='us-west-1'
```
## Run Tests
From root of repository: `go test -v ./...`
## TODO
- Bash + ZSH completion of log groups + (streams?)
- Create log streams and groups
- Delete log streams and groups
- Basic tests
