Virtualization Manager 2020.2.1 Release Notes

Release date: August 25, 2020

These release notes describe new features, improvements, and fixed issues in Virtualization Manager (VMAN) 2020.2.1. They also provide information about upgrades and describe known issues.

New VMAN features

Chargeback reports

In VMAN 2020.2.1, VMAN in the Orion Platform now delivers chargeback reporting so IT groups can gain a better understanding of the costs associated with their virtual infrastructure. VMAN allows IT to specify reporting based on hosts or clusters, choose a given timeframe, and deliver an accounting of their costs based on CPU, Memory, Storage, and vCPU usage.

Nutanix custom properties

Nutanix clusters, hosts, and VMs are now available for use in custom properties for alerting and reporting.

Orion Platform 2020.2.1 updates

See the Orion Platform 2020.2.1 release notes for details about updated Orion Platform features.

New user installation

For information about installing Virtualization Manager, see the Orion Installer and Virtualization Manager Installation Guide. After installation, use the VMAN Getting Started Guide to get started fast.

How to upgrade

For a detailed upgrade walkthrough, see the VMAN Upgrade Guide.

Fixed issues

VMAN 2020.2.1 fixes the following issues:

CASE NUMBER DESCRIPTION
00524158

In cases where multiple hosts with the same name are added, VMAN now adds all the hosts with duplicate names instead of just the first host processed.

00563025 Upgrading from VMAN 2019.4 to VMAN 2020.2.1 with the Orion database hosted as an Azure database will no longer cause _ERROR OrionDatabaseCreator - System.Data.SqlClient.SqlException (0x80131904).
00557211 Alerts in VMAN triggering from VMware Alarms now have a proper identifying display name for cluster objects.
---- Hyper-V clusters that are monitored as part of a Nutanix cluster are now properly represented in the Nutanix device summary.
00468816 Instances where adding a Nutanix cluster for monitoring has actually failed will no longer incorrectly result in a message that the Nutanix cluster was successfully added.
00291401, 00284310, 00331890, 00217434, 00334836 A new out of box alert has been included with VMAN that will warn users when a VM has multiple snapshots, which can affect polling performance.
00046423, 00042414, 00049145, 00260831 You can now filter out service tags for chassis to correct polling in situations where the same service tag exists for both a chassis and an ESX host. See this KB for more details.
00387915 The "VMs with RDM Disks" report now correctly reports VMs with RDM disks.
00448922, 00437676 The "other" sensor group is now shown for Hardware Health for vCenters and ESXi hosts.
00432655 The Virtual Machine Details page now supports and correctly displays NOC mode.
00554121, 00566643, 00567684, 00584134, 00573896, 00575613, 00595126, 00582238, 00567989, 00571627, 00573412 Users accessing Orion through Windows Authentication can now add Nutanix clusters and standalone HyperV or VMware hosts for monitoring.

Known issues

Upgrading from VMAN 8.3 with SQL server 2012 directly to VMAN 2020.2.1 causes loss of VSAN metric history
Issue: Proceeding to upgrade VMAN 8.3 to VMAN 2020.2.1 while your Orion database is running on an instance of SQL server 2012 will cause a loss of VSAN metric history.

 

Nutanix devices are not supported for Chargeback reports
Issue: Chargeback reports cannot be generated for Nutanix clusters or AHV hosts.

 

German language environments are not supported for Chargeback reports
Issue: Chargeback reports cannot be generated for VMAN instances in a German language environment.

 

Incorrect AppStack data for vCenters
Issue: AppStack data for a vCenter may in some cases be displayed incorrectly when the vCenter is deployed as a virtual machine under an ESXi host that is monitored by the same vCenter.

 

Account limitations may not work with VIM/VMAN groups
Issue: Account limitations may not work correctly in some cases with VIM/VMAN groups.

 

Custom charts show irrelevant host
Issue: Custom charts for VMAN clusters may sometimes show an irrelevant host in the chart legend.

 

Gray vCenter status and System.OutOfMemoryException in logs
Issue: In some cases, polling a vCenter may fail, resulting in a gray vCenter status. Recorded in VMAN logs is the message: "Failed to allocate a managed memory buffer of 1073741824 bytes. The amount of available memory may be low. System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown".

 

Performance issues with a single shared datastore
Issue: A single datastore being shared among many vCenters and/or hosts can cause performance issues during polling.

 

Predicted Datastore Space Depletion widget, disappearing datastores
Issue: Datastores sometimes randomly disappear from the Predicted Datastore Space Depletion widget

 

VMAN polling engines performance issues after Database maintenance
Issue: Database maintenance can in some cases cause performance issues for VMAN polling engines.

 

Incorrect status shown for vCenter
Issue: If VMAN's polling process has failed for any reason, the last known status for a vCenter is shown in VMAN. This could result in a normal, green status being shown for a vCenter when it shouldn't.

End of life, end of support, and deprecation notices

The legacy VMAN appliance has reached end of life and is no longer supported. Integrating VMAN in the Orion Platform with a legacy appliance is no longer possible.
