-- 1. コマンド等のインストール
-- 1.1 aws cli version 2 インストール
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install
aws --version
-- 1.2 jqインストール
sudo yum -y install jq
-- 2. SNSトピック作成
aws sns list-topics
aws sns list-subscriptions
aws sns create-topic --name topic01
aws sns subscribe \
--topic-arn arn:aws:sns:ap-northeast-1:999999999999:topic01 \
--protocol email \
--notification-endpoint hoge@example.com
-- 3. 複合アラームを作成
aws cloudwatch put-metric-alarm \
--alarm-name alarm01 \
--alarm-description "alarm01" \
--metric-name CPUUtilization \
--namespace AWS/EC2 \
--statistic Average \
--period 300 \
--threshold 30.0 \
--comparison-operator GreaterThanOrEqualToThreshold \
--dimensions '[
{
"Name": "InstanceId",
"Value": "i-11111111111111111"
}
]' \
--evaluation-periods 1 \
--datapoints-to-alarm 1 \
--treat-missing-data missing
aws cloudwatch put-metric-alarm \
--alarm-name alarm02 \
--alarm-description "alarm02" \
--metric-name EBSWriteBytes \
--namespace AWS/EC2 \
--statistic Average \
--period 300 \
--threshold 100000.0 \
--comparison-operator GreaterThanOrEqualToThreshold \
--dimensions '[
{
"Name": "InstanceId",
"Value": "i-11111111111111111"
}
]' \
--evaluation-periods 1 \
--datapoints-to-alarm 1 \
--treat-missing-data missing
aws cloudwatch put-composite-alarm \
--actions-enabled \
--alarm-actions arn:aws:sns:ap-northeast-1:999999999999:topic01 \
--alarm-description "alarm03" \
--alarm-name alarm03 \
--alarm-rule "ALARM("alarm01") AND ALARM("alarm02")"
aws cloudwatch describe-alarms
※管理者権限があるが、複合アラームがdescribe-alarmsで表示されない
「cloudwatch:DescribeAlarms」権限を付与しても変わらず
-- 4. 複合アラームをテスト
aws cloudwatch set-alarm-state \
--alarm-name alarm03 \
--state-reason "OK" \
--state-value OK
aws cloudwatch set-alarm-state \
--alarm-name alarm03 \
--state-reason "ALARM" \
--state-value ALARM
aws cloudwatch set-alarm-state \
--alarm-name alarm03 \
--state-reason "INSUFFICIENT_DATA" \
--state-value INSUFFICIENT_DATA
-- 5. クリーンアップ
-- アラームの削除
aws cloudwatch describe-alarms
aws cloudwatch delete-alarms \
--alarm-names alarm03
aws cloudwatch delete-alarms \
--alarm-names alarm02
aws cloudwatch delete-alarms \
--alarm-names alarm01
-- SNSトピック削除
aws sns unsubscribe --subscription-arn arn:aws:sns:ap-northeast-1:999999999999:topic01:11111111-2222-3333-4444-555555555555
aws sns delete-topic --topic-arn arn:aws:sns:ap-northeast-1:999999999999:topic01
