ElastiCache パラメータグループの設定項目を CSV 形式で一覧出力してみた

コンバンハ、千葉（幸）です。

• ElastiCache のパラメータグループ、ありますよね。
• 種類によりますけど、100個も200個も項目がありますよね。
• マネコンから見ていくの、しんどいですよね。
• というわけで、CSV 形式で出力してスプレッドシートで眺められるようにしましょう。

RDS のパラメータグループの項目を一覧出力するエントリが以前にありますので、それのオマージュです。

ElastiCache パラメータグループの値を一括で出力するコマンド

以下です。お手元の端末や CloudShell などで実行してください。

% aws elasticache describe-cache-parameters\
    --cache-parameter-group-name default.memcached1.6\
    | jq -r '["名前","許可された値","変更可能","値","ソース","タイプ","変更タイプ","説明"],
    (.Parameters[] | [.ParameterName,.AllowedValues,.IsModifiable,.ParameterValue,.Source,.DataType,.ChangeType,.Description]) | @csv' > parametergroup.csv

• describe-cache-parameters — AWS CLI 2.3.5 Command Reference

標準出力にそのまま出力した際のイメージは以下です。

% aws elasticache describe-cache-parameters\
    --cache-parameter-group-name default.memcached1.6\
    | jq -r '["名前","許可された値","変更可能","値","ソース","タイプ","変更タイプ","説明"],
    (.Parameters[] | [.ParameterName,.AllowedValues,.IsModifiable,.ParameterValue,.Source,.DataType,.ChangeType,.Description]) | @csv'
"名前","許可された値","変更可能","値","ソース","タイプ","変更タイプ","説明"
"backlog_queue_limit","1-10000",false,"1024","system","integer","requires-reboot","The backlog queue limit."
"binding_protocol","auto,ascii",true,"auto","system","string","requires-reboot","Binding protocol."
"cas_disabled","0,1",true,"0","system","boolean","requires-reboot","If supplied, CAS operations will be disabled, and items stored will consume 8 bytes less than with CAS enabled."
"chunk_size","1-1024",true,"48","system","integer","requires-reboot","The minimum amount of space to allocate for the smallest item's key + value + flags, in bytes."
"chunk_size_growth_factor","1.01-100.00",true,"1.25","system","float","requires-reboot","The growth factor controlling the size of each successive memcached chunk - each chunk will be chunk_size_growth_factor times larger than the previous chunk."
"config_max","0-64",false,"16","system","integer","requires-reboot","Maximum amount of configuration objects that can be stored at once."
"config_size_max","1024-1048576",false,"65536","system","integer","requires-reboot","Maximum size of a configuration object."
...

スプレッドシートに貼り付けると、以下のようになります。

キレイだ……。

ElastiCache パラメータグループをマネジメントコンソールから見る

マネジメントコンソールからどのように見えるかを確認しておきます。

パラメータグループの一覧から特定のグループを選択すれば、画面下部に項目が表示されます。

パラメータグループには全般的なパラメータとノードタイプ固有のパラメータがあり、デフォルトでは双方が表示されます。

実は先程の AWS CLI で取得できるのは前者の「全般的なパラメータ」のみです。ノードタイプ固有のパラメータは以下のように表され、インスタンスクラスごとに固有の値が定義されているものになります。

冒頭で「100個も200個も項目がある」と述べましたが、その大半はノードタイプ固有のパラメータです。ノードタイプ固有のパラメータとしてどういったものがあるかは、以下から確認できます。

• Memcached node-type specific parameters - Amazon ElastiCache
• Redis node-type specific parameters - Amazon ElastiCache for Redis

せっかくなので全部のパラメータグループを出力する

個々のパラメータグループの値を確認する術はわかりました。せっかくなので、デフォルトで存在するパラメータグループそれぞれに対し内容を確認してみます。

% aws elasticache describe-cache-parameter-groups\
 | jq -r '.CacheParameterGroups[].CacheParameterGroupName'\
 | while read pgname; do
    aws elasticache describe-cache-parameters --cache-parameter-group-name ${pgname}\
    | jq -r '["名前","許可された値","変更可能","値","ソース","タイプ","変更タイプ","説明"],
    (.Parameters[] | [.ParameterName,.AllowedValues,.IsModifiable,.ParameterValue,.Source,.DataType,.ChangeType,.Description]) | @csv' > ${pgname}.csv
 done

以下のコマンドと while read を組み合わせて実現しました。

終わりに

ElastiCache パラメータグループの設定項目を一括で CSV 出力する方法を確認しました。ボリュームが多すぎてマネジメントコンソールから確認していくのが大変なものは、AWS CLI で出力して手元で扱いやすくすることを検討しましょう。

ちなみに各種パラメータやバージョンによる差異は以下ページから確認できます。

• Memcached specific parameters - Amazon ElastiCache
• Redis-specific parameters - Amazon ElastiCache for Redis

何かのお役に立てば幸いです。
