Starting from this year, opvizor has two main products: opvizor Health analyzer (the historical SaaS product) and now also opvizor Snapwatcher.
Snapwatcher is a free product to help VMware administrators detect broken snapshots lurking in their virtual environments. The product has start as a free beta on Feb 25th 2015 and was created to address the broken or invalid snapshots issues in VMware virtual environments. The problem with these snapshots are that a single snapshot’s Delta-file is able to grow to the same size of the original file. And does not only mean a space issue, but also a potential performance issues and more snapshots are growing, more time will be needed to “delete” them (VMware use the term “delete all” with the mean of consolidate the snapshots to the current state).
Broken snapshots are a common problem and affect 81% of all VMware vSphere environments.
