Detection

The tab serves to setting the Collector which provides the progress and evaluation of detections.

Options:

• Detection processing
  • Detect and evaluate (evaluation schedule will not take effect) – select if the Collector should evaluate th detected data immediately after detection. The Collector will write the changes into the object tree and the Installation Registry.
    
    Note:

    Evaluation schedule will note take effect in this case.
  • Detect and schedule evaluation – select if the Collector should perform detections but not evaluate the detected data.
    The Collector only schedules the data evaluation.
    Tip:

    If you use several Collector instance in your computer network, you can have some instances detect computers only and for example one instance evaluate the detections. This will speed up data collection (and delay the evaluation thereof).
    Note:

    If you want to use scheduling, we recommend that you use this option.
• Use the PING command to determine if a computer is switched on
  • before detection with the "Agent over TCP/IP" method" – this option enables the validation of whether or not a computer is present in the network using the PING command for detections with Agent over TCP/IP.
  • before detection with the "without Agent" method – enable this option to activate the validation of whether or not a computer is present in the network using the PING command for detections without Agent.
  Note:

  
  These options are enabled by default. We recommend disabling them, only if the PING command cannot be used in your computer network, (in such case the Collector would regard all computers as switched off).
• Detect computer again in
  • __ minutes while the computer is switched off – enter in minutes after what time should the Collector try again to detect a computer that is switched off.
  • __ minutes in case of detection error – enter in minutes to after what time should the Collector try again to detect a computer whose previous detection resulted in an error.
• Process in a single block – the Collector processes requests in blocks. It will process the maximum number of requests you enter in this field and puts the waiting status at the end of the block.
  • __ computer detections – enter the maximum number of detections to be performed by the Collector within one block.
  • __ detection evaluation operations – enter the maximum number of scheduled detection evaluation operations to be performed by the Collector within one block.
    Note:

    • The Collector performing evaluation operations also assigns and removes software licenses with the Assign automatically option enabled.
    • The evaluation operations are generated by Collector instances which use the Detect and schedule evaluation option.
    • Evaluation operations are also created for re-evaluation of software detections when a new version of the Software products library is loaded.
  • Waiting status between the processing of blocks (minutes) – enter the number of minutes for the waiting status between the individual blocks.
• Only perform detections for computers matching the filter – enter the filter which defines computers to be detected by this Collector instance.

  E.g.: If you want this Collector instance to detect only computers located anywhere in the object "ALVAO Subsidiary", use the following filter:

  EXISTS( SELECT * FROM tblNodeParent NP JOIN tblNode N ON NP.lintParentNodeId=N.intNodeId WHERE NP.lintNodeId=D.lintComputerNodeId AND N.txtName=N'ALVAO Subsidiary')

  Note:

  
  This is a conditional expression in an SQL query sent to the database. This query selects the detection requests.
  The example above includes the alias D which represents the tblDetect table.
• Only perform evaluation operations for computers matching the filter – enter the filter defining computers for which the evaluation operations have to be performed by this Collector instance. The filter uses the same format as the filter used for detection.
