Overview(概述)
Activiti Probe is a web application that provides administration and monitoring capabilities to keep an Activiti Engine instance up and running. This is application is aimed at system administrators and operators whom are responsible for keeping systems and infrastructure up and running.
Activiti Probe是一個為Activiti Engine實例啟動和運行提供管理和監控能力的Web應用程序。此程序目標鎖定在那些負責保障系統和基礎設施啟動和運行的系統管理員和操作員。
Process Engine Status(流程引擎狀態)
The start page provides an overview of the status of an Activiti Engine instance, including the Activiti version you are using.
開始頁面提供Activiti引擎實例的狀態概覽，包括所使用Activiti的版本。
Job Management(作業管理)
The jobs management page allows you to perform a number of job related tasks, including:
作業管理頁面允許你完成和相關任務的多個作業，包括：
-
View List of Jobs & Job details
查看作業列表和作業細節
-
Confirm Job Status
- 確認作業狀態
-
Retry failed jobs
再次嘗試失敗的作業
-
Immediately send pending jobs for execution
立即發送掛起的執行作業
-
View exception messages for failed jobs
查看失敗作業的異常消息。
When a job is executed, it is sent to an execution queue and run asynchronously, which means that the results of executing a job may not be visible in the data table immediately. Using the checkboxes on the right-hand end of each row, you are able to send multiple jobs for execution in the same request.
當執行一個作業時，將它發送至一個執行隊列，而后再執行。這就意味著執行一個作業的結果不可能立即再數據表里面可見。使用每列右手端的復選框，你能在同一請求里面發送多個執行的作業。
If a job has failed there will be the option to view the exception, or error message from the job - this appears in a popup box on the same page.
如果作業失敗，將有一個查看異常，或者查看來自這個作業的錯誤消息的選項--這個選項出現在同一頁面彈出框里面。
Deployments(部署)
On the deployments management page you can see each deployment that has been made into the Activiti Engine and when it was made.
在部署管理頁面，你能查看每個已經部署在Activiti引擎和產生部署的時間。
The management options for each deployment are to delete it ("Delete"), or to delete the deployment and all associated files, like processes and jobs ("Delete Cascade"). It is also possible to delete multiple deployments simultaneously by selecting more than one row in the data table.
每個部署的管理選項為：刪除("Delete")或者級聯刪除("Delete Cascade")。級聯刪除能刪除部署以及所有相關聯的文件，比如流程和任務。通過在數據表中選擇多行，也可能同時刪除多個部署。
The data table can be sorted by Id, Name or Deployment Time.
可以對數據表按Id，名稱（Name）或者部署時間（Deployment Time）排序。
Database(數據庫)
The database view gives administration users a view on the raw data in the data base. To ensure the consistency of the data, it is read only and cannot be modified from this view - to update any of the records one of supplied public API methods should be used. The database view shows the following tables:
數據庫視圖讓管理員用戶查看在數據庫中的原始數據。為了確保數據的一致性，它們是只讀的，不能從本視圖中修改--為了更新任何記錄，應當使用提供的公共API方法。數據庫視圖如下圖所示。
