in ConfigMgr Console, we have a device collection for all the active devices with membership rules (SMS_R_System.Active = 1 and SMS_R_System.Client = 1). If we check device collection properties - Client Activity & Active are little confusing and wanted to understand, how are they are getting calculated and from where they are getting values.

When I do show members, i get the list with below values.

  • Client Activity = Active/Inactive or blank
  • Active = Yes

Could you please guide how this "Active=Yes" is calculated against a Device and what is the meaning of Client Activity = Active/Inactive or blank

    Hi,

    Thank you for posting in Microsoft Q&A forum.

    1,For the SCCM client to remain active, it has to meet one of below five evaluation criteria defined in the Monitor\Client Status\Client Status Settings Properties in 7 days (by default). A client will be marked as inactive when all of these has not occurred within the last 7 days.

    Client policy request

    Heartbeat discovery

    Hardware inventory

    Software inventory

    Status messages
    client status

    2,Client activity is based on communication from fast channel (Notification agent) which sends a keep-alive every 5 or 15 minutes depending on how the client is connected via fast channel (HTTP or TCP).

    The notification agent (Client) will attempt to connect the TCP to the current management point using 10123 Port. Once it’s successful, the client will send the keep-alive message every 5 minutes by default through ClientNotificationAgent.log & CCMMessaging.log to MP.

    If the client fails to establish a TCP Connection(Port 10123), the notification agent will try the HTTP protocol.

    Thanks for your time. Have a nice day!

    Best regards,

    Simon
