RabbitMQ

RabbitMQ 由 NetWorker 伺服器作為 Message Broker 代理程式服務使用,在 NetWorker 伺服器程序 (nsrd) 和 NetWorker 使用的其他服務之間提供訊息佇列機制,例如 authc、NetWorker Management Console (NMC)、NetWorker Web 使用者介面 (NWUI) 等。RabbitMQ 服務問題導致 NetWorker 伺服器服務關閉;一般訊息會記錄在 NetWorker 伺服器的 daemon.raw:

  • Linux: /nsr/logs/daemon.raw
  • Windows: ..\Program Files\EMC NetWorker\nsr\logs\daemon.raw

記錄檔:

記錄路徑會依使用的 rabbitmq-server 版本而有所不同。NetWorker 版本可能包含較新版本的 RabbitMQ。您可以在 NetWorker 安裝和 NetWorker 管理指南中找到特定版本的詳細資料,網址為: https://www.dell.com/support/home/en-us/product-support/product/networker/docs

Linux 記錄位置:
/nsr/logs/daemon.raw NetWorker 服務記錄
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/log/crash.log RabbitMQ 當機記錄,此目錄包含 crash.log#,視記錄輪替而定。
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/rabbit@localhost.log RabbitMQ 一般記錄
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/rabbit@localhost_upgrade.log RabbitMQ 升級記錄
/nsr/tmp/rabbitmq/cores/erl_crash.dump 當機堆疊追蹤記錄

 

Windows 記錄位置 (預設安裝位置)
C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw NetWorker 服務記錄
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\log\crash.log RabbitMQ 當機記錄,此目錄包含 crash.log#,視記錄輪替而定。
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\rabbit@HOSTNAME.log RabbitMQ 一般記錄
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\rabbit@HOSTNAME_upgrade.log RabbitMQ 升級記錄
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\cores\erl_crash.dump 當機堆疊追蹤記錄

 

偵錯:

偵錯選項可能因 RabbitMQ 版本而有不同。版本顯示於以下位置的 rabbitmq-server 資料夾:

  1. NetWorker 19.6-19.9: 3.8.18
  2. NetWorker 19.10:3.11.16
  1. Linux: /opt/nsr/rabbitmq-server-#.#.#
  2. Windows..\Program Files\EMC NetWorker\nsr\rabbitmq-server-#.#.#
    1. 製作原始 rabbitmq.config 的複本。
      Linux: /opt/nsr/rabbitmq-server-3.8.18/etc/rabbitmq/rabbitmq.config
      Windows: ..\Program Files\EMC NetWorker\nsr\rabbitmq-server-3.8.18\etc\rabbitmq.config
    2. 編輯 rabbitmq.config 檔案,包含下列行:
      Linux:
      %% {log_levels, [{channel, info}, {connection, info}, {federation, info}, {mirroring, info}]},
            {log_levels, [{connection, debug}, {queue, debug}]},
                 {log,
                      [{file, [{level, debug}]},
                      {categories,
                          [{connection,
                              [{level, debug}]
                          },
                          {queue,
                              [{level, debug}]
                          }
                          ]
                      }]
                  },
      注意:註解行 (%%) 已經存在,變更可新增在此行下方。
      Windows:
      在文件上方新增以下醒目顯示的行。
      [  
       {rabbit, 
       [{tcp_listeners, []}, 
       {log_levels, [{connection, debug}, {queue, debug}]},
                 {log,
                      [{file, [{level, debug}]},
                      {categories,
                          [{connection,
                             [{level, debug}]
                          },
                          {queue,
                              [{level, debug}]
                          }
                          ]
                      }]
                  },            
          {ssl_listeners, [5671]}, 
    3. 嘗試啟動 NetWorker 服務:
      Linux: systemctl restart networker
      Windows: net stop nsrd /y && net start nsrd
    4. 監控 rabbit@localhost.log (若是 Linux)、rabbit@NODE.log (若是 Windows) 及 crash.log 是否有可能阻止 RabbitMQ 啟動的錯誤。

 

警告:此偵錯的目的在於主動進行故障診斷。舉例來說,當 RabbitMQ 無法啟動時。它不應在使用中的 NetWorker 伺服器上啟用及自動執行。如果 RabbitMQ 正常運作,此偵錯可能會使用數千個與 java 的連接埠連線,這可能會使其停止回應 NetWorker 伺服器及其使用者介面。完成故障診斷後,透過將 rabbitmq.config 檔案回復到其預設設定,或回復到新增偵錯行之前建立的 rabbitmq.config 檔副本來移除偵錯。停用偵錯後,RabbitMQ 需要重新啟動 NetWorker 服務,才能重新載入組態檔案。

 

RabbitMQ 執行時,NetWorker 伺服器應讓連接埠 5671 (SSL) 進行接聽。

nsrports -t localhost -p 5671

您可以使用以下命令取得接聽 5671 上程序的程序 ID (PID)。與連接埠 5671 相關聯的程序應來自 rabbitmq-server。

Linux:

netstat -apno | grep 5671
ps -ef | grep PID
