ENA v17.0 known issues

MariaDB database corruption (ENA v17.0 GA only)

An issue in MariaDB can cause the database to restart, when a certain query undertaken by the vipman process runs on larger installations. This risks causing database corruption. A fix for this has been released in ENA v17.0 P01.

In response to this bug, the ENA v17.0 GA image has been removed from the Entuity FTP server. This has now been replaced with a single image containing ENA v17.0 and P01.

Users that have already installed ENA v17.0 GA, or are looking to install ENA v17.0 GA, must see our article on installing ENA patches for further information on this fix.

Services - permissions

In ENA, services should only be editable by users who have the 'Service Administration' permission. However, as of ENA release in June 2018, the Service Administration permission is missing (only Service Creation exists). This means that, currently, services are only editable by administrators and the original creator of the service. This will be fixed in a future patch, so that services will only be editable by users who have the Service Administration permission (regardless of which user originally created the service).

Services - managed objects

In ENA, managed objects should not be automatically considered as part of a View, just because they are in a service that is in that View. This is working for some managed objects (e.g. devices and ports), but not for others (e.g. a pure StormWorks object). The following objects in a service could be erroneously added to a View when they should not be:

• IP Address.
• IP SLA Base Poller (and all derived types, e.g. IP SLA DHCP Poller, IP SLA DNS Poller etc).
• Network Path
• Module
• Fan
• Power Supply
• Sensor
• BGP Peer
• ATM Virtual Channel
• Frame Relay DLCI

Azure support

If the user's Azure-based cloud has any storage accounts with no table service, then ENA will fail to get status, performance, storage, and network I/O data for any VMs within Azure. It will continue to get VM inventory.

This will be fixed in a future patch. In the meantime, users should contact Entuity support, who will be able to provide a hot fix.

[The metrics ENA collects about the VMs in the Azure cloud are stored in a storage account, before being pulled back to ENA. Within the storage account, these metrics are stored in a Windows Advanced Diagnostics (WAD) table. The storage account will have a table service that provides access to any table(s) in the storage account, such as the WAD table. However, users can create storage accounts with no tables and therefore no table service. If this is the case, the above issue will occur.]

Windows bug affecting patch installs (ENA v17.0/v18.0 and Entuity v19.0 on Windows Server 2016/2019):

There is a bug in Windows, as of December 2018, affecting any version of Entuity that is using Windows Server 2016 or Windows Server 2019, that can remove a temp directory that installPatch requires to run.

In Windows, user sessions are given their own temporary storage location, which is stored in the temp or tmp environment variables. This location is: C:\Users\Username\AppData\Local\Temp\session_id.

The bug, however, can remove the folder under temp for that session. The symptom of this issue is the following error:

"ERROR: Unable to install patch. The system cannot find the path specified."

This occurs even though the patch file supplied does exist.

The solution is to update the environment variable. There are two ways to do this:

• find the temp directory by running echo %TEMP% in cmd, and then create the folder manually.

or

• set a custom temp directory using the following commands in cmdset:
  

  set TEMP=\temp
  set tmp=\temp
