LibertyからDb2に接続するアプリを稼働した際、Liberty接続プール数がどのように変動しているのか把握するため、メトリックを取得しました。
取得方法と出力結果を自分用のメモとして記録します。

取得できるデータ

接続プール関連のベンダー・メトリックとしては以下のような項目を取得可能です。
この一覧自体はマニュアルより引用していますが、一部説明文が英語になっている項目についてはマニュアルに記載がないため追加したもので、説明文はPrometheus形式で取得できたHelpの文言をそのまま転記したものです。

カウンター名(%s)にはデータソースJNDI名が含まれ、「jdbc/sample」というデータソースであれば「jdbc_sample」となります。
例) jdbc/sampleというJNDI名を持つデータソースの1つ目のカウンタの名前は「connectionpool.jdbc_sample.create.total」

カウンター名	単位	説明
connectionpool.%s.create.total		プールの作成以降に作成された管理接続の総数。
connectionpool.%s.destroy.total		プールの作成以降に破棄された管理接続の総数。
connectionpool.%s.managedConnections		空きプール、共有プール、および非共有プール内の管理接続の数。
connectionpool.%s.connectionHandles		使用中の接続の数。この数には、単一の管理接続から共有される複数の接続も含まれる場合があります。
connectionpool.%s.freeConnections		空きプール内の管理接続の数。
connectionpool.%s.waitTime.total	ミリ秒	サーバーの開始以降の、すべての接続要求の待機時間の合計。
connectionpool.%s.queuedRequests.total		サーバーの開始以降の、接続プールがいっぱいであるために待機しなければならなかった接続要求の総数。
connectionpool.%s.inUseTime.total	ミリ秒	サーバーの開始以降の、すべての接続が使用中である時間の合計。
connectionpool.%s.usedConnections.total		サーバーの開始以降の、接続プールがいっぱいであるために待機したか、待機の必要がなかった接続要求の総数。現在使用中の接続は、この総数に含まれません。
connectionpool.%s.usedConnections.total		The total number of connection requests that waited because of a full connection pool or did not have to wait since the start of the server. Any connections that are currently in use are not included in this total.

メトリックの取得形式

以下2つどちらかを選択可能です。
リクエスト時にAcceptヘッダ「application/json」を指定すると、JSON形式として取得されます。カウンター名の綴りが微妙に変わるんですね。

フォーマット	取得されるmetricのカウンター名の書式(例)
Prometheus形式	vendor:connectionpool_<JNDI名(アンダーバー区切り)>_managed_connections
JSON形式	connectionpool.<JNDI名(アンダーバー区切り)>.managedConnections

メトリック取得 – 設定

環境

WebSphere Application Server 22.0.0.7 (wlp-1.0.66.cl220720220620-2217)
JDBC Driver: IBM Data Server Driver for JDBC and SQLJ 4.31.10
Db2 Server: Db2 11.5.7.0
(上記いずれも、IaaS上の非コンテナ環境)

設定

(1) mpMetricsモジュールのインストール

よくわからずmpmetrics-1.0を入れてしまいました。
最終的にserver.xmlで指定したのはmpmetrics-1.1でしたが、特に支障はありませんでした。

(2) server.xml編集

以下をserver.xmlに追記。
(メトリック取得に必要なエレメントのみ。今回利用したserver.xmlファイル全体は末尾に記載)

<featureManager>
    <feature>mpMetrics-1.1</feature>
    <feature>monitor-1.0</feature>
</featureManager>

<keyStore id="defaultKeyStore" location="myKeyStore.p12" password="yourPassword" type="PKCS12"/>
<mpMetrics authentication="false"/>

テスト環境で取得するのであくまでも最低限の、簡易的な設定です。

SSL証明書は、keyStoreエレメントを定義することによりLibertyが自動作成したものをそのまま利用
Basic認証(ユーザーログイン)なし

メトリック取得 – 出力結果

Libertyのメトリックでは、それまでに利用されたコンポーネントに関するメタデータのみ、出力されます。よって、Liberty起動後、一度もDBアクセスしない状態でメトリックを取得しても、接続プール関連の出力はなされません。
一度DBアクセスを行うアプリケーションを動かした後に取得します。

Prometheus 形式

curlコマンドで取得してみます。
URLを/metrics/vendor に変更すると、vendorの出力のみに絞られますが、今回はとりあえず全部取得。

SSL(TLS)構成要否

ずぼら人間としては本当はSSLも無しで取得したかったですが、SSL構成を省くと403エラーとなったためあきらめてSSL有り構成としました。

Error 403: Resource must be accessed with a secure connection try again using an HTTPS connection.

non-sslでのリクエスト時、messages.logに以下のようなエラーが出ていました。
