This article's purpose is to shed more light on the benefits of using the VMware KBs (Knowledge Base articles) in a proactive way - aimed at improving system resilience and performance. This can be achieved by minimizing the likelihood of service-impacting incidents or events from occurring and/or to mitigate the impact if they do occur.
What are the VMware KBs?
Why to use the VMware KBs for proactive analysis?
Because we estimate that around 90% of issues happening on VMware vSphere are already known issues and documented in a VMware knowledge base article. This is based on our vast experience working with many large enterprise vSphere environments. All the technical staff of Runecast is VCAP (VMware Advanced Professional) certified and we have also a VCDX (VMware Certified Design Expert) among us. Before Runecast, we were part of the VMware Center of Excellence within IBM GTS. We have seen so many incidents manifesting themselves over and over in different locations, most of them relating to a known issue (described in a KB). The common conclusion for those support teams dealing with the issues was: "if we only knew it before..." . We thought there must be a better way to do this, so we've quit our dream jobs and founded Runecast.
How to do it best?
This is a tremendous effort, it is not impossible but it is a huge challenge:
This is exactly what we did at Runecast: we developed a product which does all of the above ... automatically ... You can deploy it (OVA virtual appliance), connect it to the vCenter and click "Analyze Now". It will perform tens of thousands of configuration checks in a couple of minutes and will report if any VMware KB can plague your environment.
It is a great effort, but thanks to the algorithms we are using for parsing and classifying the KBs, we are able to cover the vSphere suite on the VMware Knowledge Base.
