handson-cli-s3-function)¶

目的¶

CloudWatch Logsロググループ"/aws/lambda/handson-cli-s3-function"からログフィルターを利用してログイベントを取得します。

パラメータの指定¶

作業に必要なパラメータを変数に格納をします。

0. リージョンの指定

リージョンを指定します。

環境変数の設定
export AWS_DEFAULT_REGION='ap-northeast-1'

1. CloudWatch Logsロググループ名

CloudWatch Logsロググループ名を指定します。

変数の設定:

LOGS_GROUP_NAME='/aws/lambda/handson-cli-s3-function'

2. ログイベント数

取得するログイベント数を指定します。

変数の設定:
LOGS_EVENT_MAX_ITEMS='7'

各変数に正しいパラメータ値が格納されていることを確認します。

変数の確認:

cat << END

  # 0. AWS_DEFAULT_REGION:"ap-northeast-1"
       AWS_DEFAULT_REGION="${AWS_DEFAULT_REGION}"

  # 1. LOGS_GROUP_NAME:"/aws/lambda/handson-cli-s3-function"
       LOGS_GROUP_NAME="${LOGS_GROUP_NAME}"
  # 2. LOGS_EVENT_MAX_ITEMS:"7"
       LOGS_EVENT_MAX_ITEMS="${LOGS_EVENT_MAX_ITEMS}"

END

手順¶

ログフィルターを利用してCloudWatch Logsログイベントを取得します。

変数の確認:

cat << END

  # LOGS_GROUP_NAME:"/aws/lambda/handson-cli-s3-function"
    LOGS_GROUP_NAME="${LOGS_GROUP_NAME}"
  # LOGS_EVENT_MAX_ITEMS:"7"
    LOGS_EVENT_MAX_ITEMS="${LOGS_EVENT_MAX_ITEMS}"

END

コマンド:

aws logs filter-log-events \
  --log-group-name ${LOGS_GROUP_NAME} \
  --max-items ${LOGS_EVENT_MAX_ITEMS}

結果(例):
