Analyze censhare commands

Locate relevant information about commands in the censhare Admin Client and the server logfiles to trace commands for errors.

Identify command to trace

In this example, we use the Create Text Preview (automatic) command.

  1. Log into the censhare Admin Client and go to Configuration | Modules | Previews.
  2. Double-click Create Text Preview (automatic) to open it.
  3. Under Description, you see that the actual command name is: preview_maker.aa-preview-text. The name Create Text Preview (automatic) is the localized display name of the command. The localized English title comes as a localization file. This is displayed in the General Setup section under Title by the variable ${reg-title-aa-preview-text}.


We have identified the command name as preview_maker.aa-preview-text.

Find the running command

  1. In the censhare Admin Client, go to the Status | Commands folder and double-click it.
  2. From the drop-down in the dialog, select Commands | contains and paste the command name or parts of it into the empty field.
  3. Now the actual running command is shown, identified by its name and an ID.

    Here, you can identify the first problems:

    • If the command is not listed, the command was canceled by accident and you have to restart it.
    • If a command has a large queue, this can indicate a performance problem or an incorrectly configured command. In that case, you can contact support for help.
  4. Double-click the command to see the command details. You can see the source code of the command and its current process ID. This ID changes when the command or the server is restarted.
  5. Copy the command ID to the clipboard.


Trace the process in the server logs

  1. Log into the server by the terminal as corpus.
  2. Go to the logs directory.
    The shortcut wl should bring you there.

  3. Grep for the process ID like this:

    CODE 
    grep cs-srv41.20150302.153504.672 server-0.0.log

    The result will look like this:

    CODE 
    2015.03.13-17:24:10.971 FINE : T022: CommandExecutor: cs-srv41.20150302.153504.672[system]: sync fork of event command preview_maker.aa-preview-text started

    The command ran successfully. This is indicated by the "completed all" phrase.

  4. Copy the timestamp of the command, open the server log with the command and search for it to find out more information of the command. In this case, it executed several steps to create the text preview.
