saw is a multi-purpose tool for AWS CloudWatch Logs

• 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"

• Basic

  # Get list of log groups
  saw groups
  
  # Get list of streams for production log group
  saw streams production

• Watch

  # 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

  # 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

By default Saw uses the region and credentials in your default profile. You can override these to your liking using the command line flags:

# Use personal profile
saw groups --profile personal

# Use us-west-1 region
saw groups --region us-west-1

docker run --rm -it -v ~/.aws:$HOME/.aws tbrock/saw

brew tap TylerBrock/saw
brew install saw

# Using yay
yay saw

# Using makepkg
git clone https://aur.archlinux.org/saw.git
cd saw
makepkg -sri

rpm -i <link_to_rpm_you_need_from_releases>

wget <link_to_deb_you_need_from_releases>
sudo dpkg -i <the_deb_name>

• Install go
• Configure your GOPATH and add $GOPATH/bin to your path
• Run go install github.com/TylerBrock/saw@latest

• Add %GOPATH%/bin to your path (optional)
• Run from gopath/bin (If not in your path)

  cd %GOPATH%/bin
  saw ...
  

Alternatively you can hard code these in your shell's init scripts (bashrc, zshrc, etc...):

# Export profile and region that override the default
export AWS_PROFILE='work_profile'
export AWS_REGION='us-west-1'

From root of repository: go test -v ./...

• Bash + ZSH completion of log groups + (streams?)
• Create log streams and groups
• Delete log streams and groups
• Basic tests
