cw-pipe

Node utility for piping stdin to CloudWatch Logs

Motivation

I wanted a way to capture the output of an AppleScript in CloudWatch. While I could write the output to a file and then upload the file to CloudWatch, I decided to write this utility which would directly pipe the data from stdin. The data is piped in real time, however it batches ten lines at a time to cut down on the number of requests sent to CLoudWatch.

Getting Started

Install the module

npm install -g cw-pipe

When piping to CloudWatch the string passed to cw-pipe will be prefixed to each log line

export LOG_GROUP_NAME="my-log-group"
export LOG_STREAM_NAME="my-log-stream"
ls | cw-pipe "stdout"

If you also want to pipe stderr the best solution I could find is to pipe to stdout, switch the file descriptors, and then pipe to stderr

export LOG_GROUP_NAME="my-log-group"
export LOG_STREAM_NAME="my-log-stream"
( ls | cw-pipe stdout ) 3>&1 1>&2 2>&3 | cw-pipe stderr
