Setting the Logging Level of NSX Components

You can set the logging level for each NSX component.
The supported levels vary by component, as shown here.

nsxmgr> set
  hardware-gateway  Show Logical Switch Commands
  PACKAGE-NAME      Set log level
  controller        Show Logical Switch Commands
  host              Show Logical Switch Commands

nsxmgr> set hardware-gateway agent 10.1.1.1 logging-level
  ERROR
  WARN
  INFO
  DEBUG
  TRACE

nsxmgr-01a> set <package-name> logging-level
  OFF
  FATAL
  ERROR
  WARN
  INFO
  DEBUG
  TRACE

nsxmgr> set controller 192.168.110.31
  java-domain    Set controller node log level
  native-domain  Set controller node log level

nsxmgr> set controller 192.168.110.31 java-domain logging-level
  OFF
  FATAL
  ERROR
  WARN
  INFO
  DEBUG
  TRACE

nsxmgr> set controller 192.168.110.31 native-domain logging-level
  ERROR
  WARN
  INFO
  DEBUG
  TRACE

nsxmgr> set host host-28
  netcpa  Set host node log level by module
  vdl2    Set host node log level by module
  vdr     Set host node log level by module

nsxmgr> set host host-28 netcpa logging-level
  FATAL
  ERROR
  WARN

VXLAN Overview

As its name indicates, VXLAN is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility. Compared to VLAN, VXLAN offers the following benefits:

   Flexible placement of multitenant segments throughout the data center: It provides a solution to extend Layer 2 segments over the underlying shared network infrastructure so that tenant workload can be placed across physical pods in the data center.
   Higher scalability to address more Layer 2 segments: VLANs use a 12-bit VLAN ID to address Layer 2 segments, which results in limiting scalability of only 4094 VLANs. VXLAN uses a 24-bit segment ID known as the VXLAN network identifier (VNID), which enables up to 16 million VXLAN segments to coexist in the same administrative domain.
   Better utilization of available network paths in the underlying infrastructure: VLAN uses the Spanning Tree Protocol for loop prevention, which ends up not using half of the network links in a network by blocking redundant paths. In contrast, VXLAN packets are transferred through the underlying network based on its Layer 3 header and can take complete advantage of Layer 3 routing, equal-cost multipath (ECMP) routing, and link aggregation protocols to use all available paths.

VMware Identity Manager (vIDM)

VMware Identity Manager can act as an identity platform or it can federate identity from other identity platforms such as ADFS, Okta or another SAML platforms. This is how it works:
  1. A user browses to the vRealize Automation home page
  2. The unauthenticated user is redirected to VMware Identity Manager which has been configured as identity management platform
  3. If the browser does not already have a session established with VMware Identity Manager the user is redirected the customer's identity platform
  4. The customer enters in their credentials into the 3rd Party identity platform
  5. A SAML assertion is generated by the identity platform and passed to vIDM
  6. VMware Identity Manager generates an OAuth2 token and passes it to vRealize Automation
  7. vRealize Automation validates the OAuth2 token and grants access
This provides organizations with a wide range of options for integrating vRealize Automation into their existing identity management system.
