A simple script to push a JSON log to AWS CLoudWatch

#!/bin/bash

AWS_REGION="--region XXX_REGION"
AWS_PROFILE="--profile XXX_PROFILE"
LOG_GROUP="XXX_YOUR_LOG_GROUP"

LOG_STREAM="$(whoami)-$( date "+%Y%m%d-%H-%M-%S")"

aws logs create-log-stream --log-group-name $LOG_GROUP --log-stream-name $LOG_STREAM $AWS_REGION $AWS_PROFILE

# Create a new Logstream and ush all the logs
SEQUENCE=""
while IFS='' read -r line || [[ -n "$line" ]]; do
    TIMESTAMP=$(echo $line| jq .timestamp)
    JSONOBJ=$(echo $line| jq tostring)
    echo "SENDING $TIMESTAMP $line"
    SEQ=$(aws logs put-log-events \
        --log-group-name $LOG_GROUP \
        --log-stream-name $LOG_STREAM \
        --log-events "{\"message\":$JSONOBJ,\"timestamp\":$TIMESTAMP}" \
        $SEQUENCE \
        $AWS_REGION \
        $AWS_PROFILE | jq .nextSequenceToken --raw-output)

    echo $SEQ

    SEQUENCE=" --sequence-token $SEQ"    
done < "$1"
