しばらくSensuをインストールしようとしましたが、インストール ガイドに従っていました。インストール中はすべてうまくいきましたが、ドキュメントからサンプル チェックを追加していると、Sensu が突然 RabbitMQ に接続できなくなりました。具体的には、check_cron.json構成を追加したとき。再起動して構成を削除しようとしましたが (その後、もう一度再起動しました)、Sensu は一貫してタイムアウトになります。RabbitMQ がインストールされて実行されていることは注目に値します。管理インターフェイスを介してナビゲートすることも可能ですが、Sensu はそれを認識していないようです。

以下は私のサーバーログです：

rabbitmq サーバーで ssl 証明書を使用している場合は、証明書に問題がある可能性があります。github にスクリプトがあり、それを複製して次のコマンドを実行します。

git clone git://github.com/joemiller/joemiller.me-intro-to-sensu.git
cd joemiller.me-intro-to-sensu/

./ssl_certs.sh clean
./ssl_certs.sh generate

次に、これらの証明書を使用するように Rabbitmq を構成します。

mkdir /etc/rabbitmq/ssl
cp server_key.pem /etc/rabbitmq/ssl/
cp server_cert.pem /etc/rabbitmq/ssl/
cp testca/cacert.pem /etc/rabbitmq/ssl/

そして、この構成を /etc/rabbitmq/rabbitmq.config に追加します。

[
  {rabbit, [
    {ssl_listeners, [5671]},
    {ssl_options, [{cacertfile,"/etc/rabbitmq/ssl/cacert.pem"},
                   {certfile,"/etc/rabbitmq/ssl/server_cert.pem"},
                   {keyfile,"/etc/rabbitmq/ssl/server_key.pem"},
                   {verify,verify_peer},
                   {fail_if_no_peer_cert,true}]}
  ]}
].

ここで、使用する証明書をrabbitmqに伝えます。証明書のパスが証明書のコピー先と同じであることを確認してください。

update-rc.d sensu-server defaults
update-rc.d sensu-api defaults
update-rc.d sensu-client defaults
update-rc.d sensu-dashboard defaults

次に、以前に行ったように、次を使用して SSL client_key と証明書をコピーします。

cp client_key.pem client_cert.pem  /etc/sensu/ssl/

そして、さまざまな構成を /etc/sensu/config.json に追加します。
