Using nJAMS Replay command line tool

Overview

nJAMS Replay provides a command line interface in addition to the graphical user interface.

Using nJAMS Replay from the GUI is very useful when you want to modify input data and start a single Replay on an interactive basis. You can select a single entry, modify the input data, start the Replay, and watch the result instantly.

But if you want to Replay many process executions or want to start Replay(s) as part of a batch script, a command line interface is required. The command line interface of nJAMS Replay allows you to search for log entries based on search parameters you know from using the Query in nJAMS GUI. The result of the search can be displayed on the console or can be stored into a text file that serves as the input for a Replay. If required, you can modify the text file before you start the Replay.

A typical procedure of using the command line interface is as follows:

  1. Execute command line tool to search for the entries that should be replayed afterwards. The result set including the input data will be stored in a text file.
  2. Make sure the result set corresponds exactly to your expectation.
  3. If applicable, modify the result of the search by using a text editor.
  4. Finally execute the command line tool again to Replay the entries of the text file

Note

This release of nJAMS Replay command line tool requires Java 11.

Examples

(1) Search for specific process executions:
 

The following example searches for entries of a particular process of any status within a specific time interval. The results are stored in separate files in a specified folder.

java -jar njams-replay-plugin-commandline-5.1.0.jar
    -i admin admin http://myserver:8080/njams/
    -q -sf 2020-06-02T16:40:00 -st 2020-06-02T16:50:00
    -sp DO ">fs_pres>C1_Services-1>C1_Services-1-C1_Services>OrderServices/C1/Starter_C1_SendOrder.process"
    -sst SUCCESS,WARNING,ERROR
    -qm ids
