vserver services ndmp log start

Description​

This command is used to start logging on an active NDMP session on a vserver.

Parameters​

-vserver <vserver name> - Vserver

This parameter specifies the name of the Vserver.

-session-id <text> - Session Identifier

This parameter specifies the NDMP session-id on which logging needs to be started.

-filter <text> - Level Filter

Use this parameter to specify the filter for a particular session ID. This parameter controls the NDMP modules for which logging is to be enabled. This parameter can take five values. They are as follow : all, none, normal, backend or "filter-expression". The default value for this is none.

• all turns on logging for all modules.
• none disables logging for all modules.
• normal is a short cut parameter that enables logging for all modules except verbose and io_loop. The equivalent filter string is all-verbose-io_loop
• backend is a short cut parameter that enables logging for all modules except verbose, io_loop, ndmps and ndmpd. The equivalent filter string is all-verbose-io_loop-ndmps-ndmpp
• (filter-expression) is a combination of one or more modules for which logs needs to be enabled. Multiple module names can be combined using following operators :
  • - to remove the given module from the list of specified modules in the filter string. For example the filter all-ndmpp will enable logging for all modules but not ndmpp.
  • ^ to add the given module or modules to the list of modules specified in the filter string. For example the filter ndmpp^mover^data will enable logging for ndmpp, mover and data.

The possible module names and a brief description is given below:
