Configuring VxMS and vhd logging

The following procedure describes how to configure VxMS logging for NetBackup.

Except as noted in this topic, you can also use the Logging Assistant (in the NetBackup Administration Console) to configure VxMS logging. For details on the Logging Assistant, see the NetBackup Administrator's Guide, Volume I.

Note:

VxMS logging may require significant resources on the Hyper-V server.

VxMS and vhd logging on the Hyper-V server

To configure VxMS and vhd logging on the Hyper-V server

Create the VxMS log directory:
install_path\NetBackup\logs\vxms
Note:
For logging to occur, the VxMS folder must exist.
Note:
If you have run the NetBackup mklogdir.bat command, the VxMS log directory already exists.
See NetBackup logs for Hyper-V and how to create them.
In the Windows registry, create the DWORD registry entry VXMS_VERBOSE in the following location:
HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion > Config
To configure the logging level, set the numeric value of VXMS_VERBOSE to 0 or greater. Larger numbers result in more verbose logs.
See Table: VxMS logging levels for the available logging levels.
To change the log location:
- Open regedit and go to the following location:
  HKEY_LOCAL_MACHINE > SOFTWARE > Veritas > NetBackup > CurrentVersion
- Create the registry entry vxmslogdir with a string value (REG_SZ). For the string value, specify the full path to an existing folder.
Note:
You can use NTFS compression on VxMS log folders to compress the log size. The new logs are written in compressed form only.
Note:
If the VxMS log location is changed, the Logging Assistant does not collect the logs.

VxMS logging levels

Table: VxMS logging levels lists the VxMS logging levels.

Note:

Logging levels higher than 5 cannot be set in the Logging Assistant.

Note:

Logging levels higher than 5 should be used in very unusual cases only. At that level, the log files and metadata dumps may place significant demands on disk space and host performance.

Table: VxMS logging levels

Level	Description
0	No logging.
1	Error logging.
2	Level 1 + warning messages.
3	Level 2 + informative messages.
4	Same as level 3.
5	Highly verbose (includes level 1) + auxiliary evidence files (.mmf, .dump, VDDK logs, .xml, .rvpmem). You can set the logging level for the VDDK messages.
6	VIX (VMware virtual machine metadata) dumps only.
7	VHD (Hyper-V virtual machine metadata) dumps only.
> 7	Full verbose + level 5 + level 6 + level 7.
