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^moverdata will enable logging for ndmpp , mover and data .

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

Examples

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
