SCVMM Refreshers

Hi everyone!
If you are like me, and have started using System Center Virtual Machine Manager (SCVMM) quite recently, after some time you cannot help wonder, how often and what triggers those refresh jobs that you can see in the Jobs tab.
However, you will be surprised to find out that some of the internal SCVMM refreshers are not even visible and their jobs run in the background, without being recorder within the SCVMM Administration Console. However, keep in mind that the manual equivalent of these refreshers will trigger a job being recorded in the Jobs tab.

While digging around the publicly available data, and actually searching for specific information about SCVMM 2016, i was unable to find anything about the 2016 version, but i did find some interesting information around the older versions.

First piece of information you can find is the official Microsoft Technet article around the SCVMM 2008 Refreshers – https://docs.microsoft.com/en-us/previous-versions/system-center/virtual-machine-manager-2008-r2/dd221389(v=technet.10) . Unfortunately, not sure how much this version is being used now, and being the first version, its bound to change once the product evolves.

The “newest” piece of information I was able to find, revolves around the SCVMM 2012 SP1 product, and the VMM refreshers frequencies that have changed are written in the table here https://blogs.technet.microsoft.com/chengw/2012/09/17/update-on-vmm-refreshers-what-has-changed-and-what-this-means-to-you/ , with reference to another, older article about VMM 2008 for refreshers that haven’t changed their intervals. https://blogs.technet.microsoft.com/chengw/2008/10/01/all-about-refreshers-2/

I am yet to find something from Microsoft around the 2016 version but if i do i will post it here, especially since i noticed that in a particular environment I am working with the intervals do not match the ones stated in the articles.
