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(gè)為Activiti Engine實(shí)例啟動(dòng)和運(yùn)行提供管理和監(jiān)控能力的Web應(yīng)用程序。此程序目標(biāo)鎖定在那些負(fù)責(zé)保障系統(tǒng)和基礎(chǔ)設(shè)施啟動(dòng)和運(yùn)行的系統(tǒng)管理員和操作員。
Process Engine Status(流程引擎狀態(tài))
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(shí)例的狀態(tài)概覽，包括所使用Activiti的版本。
Job Management(作業(yè)管理)
The jobs management page allows you to perform a number of job related tasks, including:
作業(yè)管理頁面允許你完成和相關(guān)任務(wù)的多個(gè)作業(yè)，包括：
-
View List of Jobs & Job details
查看作業(yè)列表和作業(yè)細(xì)節(jié)
-
Confirm Job Status
- 確認(rèn)作業(yè)狀態(tài)
-
Retry failed jobs
再次嘗試失敗的作業(yè)
-
Immediately send pending jobs for execution
立即發(fā)送掛起的執(zhí)行作業(yè)
-
View exception messages for failed jobs
查看失敗作業(yè)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(dāng)執(zhí)行一個(gè)作業(yè)時(shí)，將它發(fā)送至一個(gè)執(zhí)行隊(duì)列，而后再執(zhí)行。這就意味著執(zhí)行一個(gè)作業(yè)的結(jié)果不可能立即再數(shù)據(jù)表里面可見。使用每列右手端的復(fù)選框，你能在同一請(qǐng)求里面發(fā)送多個(gè)執(zhí)行的作業(yè)。
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(yè)失敗，將有一個(gè)查看異常，或者查看來自這個(gè)作業(yè)的錯(cuò)誤消息的選項(xiàng)--這個(gè)選項(xiàng)出現(xiàn)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(gè)已經(jīng)部署在Activiti引擎和產(chǎn)生部署的時(shí)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(gè)部署的管理選項(xiàng)為：刪除("Delete")或者級(jí)聯(lián)刪除("Delete Cascade")。級(jí)聯(lián)刪除能刪除部署以及所有相關(guān)聯(lián)的文件，比如流程和任務(wù)。通過在數(shù)據(jù)表中選擇多行，也可能同時(shí)刪除多個(gè)部署。
The data table can be sorted by Id, Name or Deployment Time.
可以對(duì)數(shù)據(jù)表按Id，名稱（Name）或者部署時(shí)間（Deployment Time）排序。
Database(數(shù)據(jù)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(shù)據(jù)庫視圖讓管理員用戶查看在數(shù)據(jù)庫中的原始數(shù)據(jù)。為了確保數(shù)據(jù)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(yīng)當(dāng)使用提供的公共API方法。數(shù)據(jù)庫視圖如下圖所示。
