Why Is It Important to Monitor VMware NSX Best Practices?

As mentioned VMware NSX is VMware’s software defined networking solution that allows overlaying logical networks on top of the physical network infrastructure as well as provide network security and microsegmentation.  It sounds simple in concept, however, there are a lot of moving parts and pieces to a working NSX environment.  Underneath the hood, there are a lot of complexities that comprise the NSX software defined solution.

As you can imagine managing and configuring VMware NSX brings along an added layer of complexity and settings that must be configured, upgraded, and maintained with skill to keep from inadvertently impacting production workloads.

Runecast Analyzer v1.8 allows automating the best practices configuration of VMware NSX by scanning the critical NSX components, including:

Navigate to https://<your Runecast appliance IP or FQDN>:5480 and login.  Default username/password combo (definitely change this if you haven’t already):

user: rcadmin
pass: admin

Navigate to the Update tab and click the Check Updates button to begin the check for a later version of Runecast.  As you can see below, the appliance found the update to v1.8.1.0 from the current installed version of v1.7.5.0.
