09:01:49 AM UTC+9   db01    DB instance restarted
09:01:39 AM UTC+9   db01    Multi-AZ instance failover started

RDSメンテナンスウィンドウの指定

RDSイベントログの取得

管理コンソールからは過去2日分しか見えないが、awscliならそれ以上に取得できる。

AWS_PROFILE=default
AWS_REGION=ap-northeast-1
RDS_ID=db1

aws rds describe-events \
 --source-identifier $RDS_ID --source-type db-instance --start-time "$(date -u +%Y-%m-%d)T00:00:00" \
 --query 'Events[].[Date,Message]' \
 --profile $AWS_PROFILE \
 --region $AWS_REGION \
 --output text

2021-01-01T00:12:11.000000+00:00        Backing up DB instance
2021-01-02T00:13:22.000000+00:00        Finished DB Instance backup

DBParameterGroupNameの取得

AWS_PROFILE=default
for region in $(aws --profile $AWS_PROFILE ec2 describe-regions --query "Regions[].[RegionName]" --output text); do \
  for i in $(aws --profile $AWS_PROFILE --region $region rds describe-db-parameter-groups --query 'DBParameterGroups[?contains(DBParameterGroupFamily, `mysql`)].[DBParameterGroupName]' --output text); do \
    echo "$region, $i"; \
  done \
done
