Getting the 'absent' Devices into a current MAP inventory RRS feed

  • Question

  • Many times, a customer will run MAP only to discover that Desktops are missing from the inventory scan -  they're either turned off or laptops that aren't yet attached.    We suggest that MAP be run on Tues -Thurs, and after 10 am in order to avoid devices that yet to be on the network.

    Unfortunately, there still will be some desktop devices missing.  What is the best way for MAP to re-scan for new devices without  starting the whole process from scratch?  I'm under the impression that 'refresh inventory' attempts to re scan devices that failed the WMI inventory.... but doesn't necessarily 'rescan' for those delinquent devices.

  • When MAP inventories a machine it has a list of data objects it expects to collect depending on the inventory scenario(s) chosen (1st page of the wizard). Once MAP collects each data object, it records what it finds and will not try for that information again. After all expected objects have been collected MAP will not attempt to inventory that machine in any future runs. The list of machines in MAP’s “discovered” list is accumulative and MAP will continue to retry any of the machines that are on that list that hasn’t had 100% of the expected data objects collected. MAP will never delete a machine from the list. If a machine is no longer in the environment but MAP had discovered its existence at one time, MAP will keep retrying until 100% complete.

    With that in mind, if you want to run the inventory multiple times to give MAP a chance to collect data previously missed, you can simply inventory the local MAP machine over and over and MAP will retry the others until they complete.

    To do this, simply choose the manual entry discovery method on page 2 of the wizard. Then make sure you enter all of the needed credentials for the other machines in the All Computers Credentials page. The last page is where you enter the host name for the local MAP machine and make sure you have it use All Computers Credentials. This way MAP will quickly inventory (or later, skip) the local machine and move on to the retries from the previous inventories.
