vserver services ndmp log start

Start logging for the specified NDMP session

Availability: This command is available to cluster and Vserver administrators at the advanced privilege level.


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


-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:

The following example shows how to start logging on a specific NDMP session 1000:35512, running on vserver cluster1-01 with filter all.

			cluster1::*> vserver services ndmp log start -vserver cluster1-01 -session-id 1000:35512 -filter all
