     Column Name  
     Description  
  
 
 
  
    Hostname 
     The name of the host machine.  
  
  
    Machine 
     The machine template used to connect the corresponding host machine to Orchestrator.  
  
  
    Runtimes 
     The number of runtimes associated with a machine template. Each host machine connected using that machine template secures this number of licenses from the tenant's pool of licenses.  
  
  
    In Use 
     The number of runtimes currently being consumed out of the number of runtimes secured on that host machine. A runtime is consumed during job execution.  
  
  
    Runtime type 
     The type of license.  
  
  
    Service username 
     The identity under which unattended jobs are executed. For service accounts, this is empty.  
  
  
    Status 
     The connection status of each host machine.  
  
  
    Last Heartbeat 
     Time elapsed since the last heartbeat. Hover over this field to see the exact time of the last heartbeat.  
  
  
    Version 
     The version of the robot connected to the machine.  
  
  
    Troubleshooting 
     Indicates if the corresponding unattended session has a troubleshooting session enabled.  
  
  
    Maintenance 
     Allows you to take the machine offline in order to perform maintenance on it.  By default, this toggle is disabled.  Once enabled, a confirmation window is displayed, asking you if you want to: 
      
          Wait for running jobs to finish on their own (this is the default option).  
          Kill all running jobs now.  
      
 When you select Confirm , it enables the maintenance mode, while Cancel revokes the request to enter maintenance mode.  Pending jobs keep their status while they await to be picked up by another available machine or by the same machine, once it is back online.

On the **Monitoring** page, under the **Unattended Sessions** tab, you cannot sort items by status. Alternatively, we recommend using the **Status** filter instead.
