ロボット ログを管理する

Setting the logging level

You can change the log level via:

• the Log Level setting in Assistant > Preferences > General page. By default, it is set to Information. For the Service Mode Robot, you need administrator permissions.

• the Logging Level setting in Orchestrator > Manage Access > Users > user or robot account > Robot Settings page. By default, it is set to Information.

  注:

  The log level you set in Orchestrator overrides the level configured in Assistant.

Deleting log files

To prevent disk space usage, you can choose to archive log files after they reach a specific count. Configure your logging files in the NLog.config file, under the <target> section, as follows:

• By adding the properties archiveNumbering="Date" and archiveEvery="Day", you instruct the system to archive log files on a daily basis, with each archive named by the date.
• The property archiveDateFormat="yyyy-MM-dd" sets the format for the dates in the archive file names.
• With archiveFileName="${WorkflowLoggingDirectory}/{#}_Execution.log", you specify the location and format for the archived file names.
• The maxArchiveFiles="10" property sets a limit to only keep the 10 most recent archived log files.

例:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <variable name="WorkflowLoggingDirectory" value="${specialfolder:folder=LocalApplicationData}/UiPath/Logs" />
  <rules>
    <logger name="WorkflowLogging" writeTo="WorkflowLogFiles" final="true" />
  </rules>
  <targets>
    <target type="File"
      name="WorkflowLogFiles"
      fileName="${WorkflowLoggingDirectory}/${shortdate}_Execution.log"
      layout="${time} ${level} ${message}"
      keepFileOpen="true"
      openFileCacheTimeout="5"
      concurrentWrites="true"
      encoding="utf-8"
      writeBom="true"
      archiveNumbering="Date"
      archiveEvery="Day"
      archiveDateFormat="yyyy-MM-dd"
      archiveFileName="${WorkflowLoggingDirectory}/{#}_Execution.log"
      maxArchiveFiles="10"
    />
  </targets>
</nlog>

Customizing detailed logs

Verbose-level logs may contain extra information and can be large. You can control this by customizing the UiPath.Executor.exe.config file. Add the following XML snippet under the <system.serviceModel> section, then restart the Robot Service:

<tracking>
    <profiles>
        <trackingProfile name="StandardProfile">
         <workflow>
          <activityStateQueries>  
            <activityStateQuery activityName="*">
                <states>  
                    <state name="Faulted"/>  
                </states>
                <arguments>  
                    <argument name="*"/>  
                </arguments> 
                 <variables>  
                    <variable name="*"/>  
                </variables>             
            </activityStateQuery>
          </activityStateQueries>    
         </workflow>
        </trackingProfile>       
    </profiles>
</tracking>

The <states> tag contains sub-tags for each state you want to log. If it only contains <state name="Faulted"/>, then only activities that end in a Faulted state, meaning they encountered an error, are logged.

To include other states, use <state name="Executing"/>.

You can customize variables and arguments as well. Refer to the Microsoft documentation.

Managing driver diagnostic logs

To enable driver tracing:

1. Open Command Prompt with administrator rights.

2. Access the installation directory using the cd argument, such as cd C:\Program Files\UiPath\Studio.
3. UiRobot.exe --enableLowLevel コマンドを実行します。

To disable driver tracing:

1. Open Command Prompt with administrator rights.

2. Access the installation directory using the cd argument, such as cd C:\Program Files\UiPath\Studio.
3. UiRobot.exe --disableLowLevel コマンドを実行します。

診断ツールを使用する

Check the About the Diagnostic Tool page in the Studio guide for information about how you can configure it to retrieve execution logs.
