CloudWatchのログをlocalにdownload

CloudWatchのをlocalにdownloadしたい

get-log-eventsで落とせるとおもったけど、これloopさせないと全部取れないんですね。

download.sh

#!/bin/bash
log_group_name=$1
log_stream_name=$2
response=`aws logs get-log-events --log-group-name ${log_group_name} --log-stream-name "${log_stream_name}" --start-from-head`
next_token=`echo $response | jq -r '.nextForwardToken'`
while [ -n "${next_token}" ]; do
    echo ${response} | jq -r .events[].message
    response=`aws logs get-log-events --log-group-name ${log_group_name} --log-stream-name "${log_stream_name}" --start-from-head --next-token ${next_token}`
    next_token=`echo $response | jq -r '.nextForwardToken'`
    if [[ $(echo ${response} | jq -e '.events == []') == "true" ]]; then
        break
fi
done

./download.sh /aws/lambda/hoge '2020/00/00/[$LATEST]xxxxxx'

注意　lambdaのlog streamは＄があるのでシングルクォートで囲む
