Using Module-Specific Console Commands
In version 3.0, most module-specific system console commands have changed. How commands are issued depends upon whether a module is a singleton or not. Use the module list command from the system console to determine whether a module is a singleton or refer to “All Modules”. This command also displays the instance name of a module—this information is also necessary when issuing console commands. Find below partial output of the module list command:
... Module: statp:statp Scope_Name: statp Instance_Name: statp Enabled: enabled API: Generic Name: stats_producer.c Description: Stats producer module Module: ds_core Scope_Name: ds_core Enabled: enabled API: Singleton Name: ds_core.c Description: generic datasource module ...
This output shows both a singleton and a non-singleton module. The instance name of a module is the name that you choose when the module is created. Non-singleton module commands are issued using Scope_Name:Instance_Name followed by the command. For example, when you have an ec_logger module named ec_logger1, issue the help command in the following way:
05:47:04 /tmp/2025> ec_logger:ec_logger1 help
Singleton module commands are executed exactly as they were in version 2.2, using the module scope name followed by the command.
As of version 3.0, all module-specific commands related to setting or getting module options have been removed. Use the following syntax to set or get module-specific options: config [set | eval | get] Scope_Name [Instance_Name] option [value] . Note that there is no ‘:’ between the Scope_Name and the Instance_Name. For example, when you have a sieve module named sieve1, you can set the cache_life option from the system console in the following way:
05:47:04 /tmp/2025> config set sieve sieve1 cache_life 300
In version 2.2 it was possible to set and get module-level debugging from the system console in the following way: debug module module_name [level] .
In version 3.0, you set and get module-level debugging using the config command. The debug level is set in the same way as any other module option. For example, use the following syntax to set the debug level of an ec_logger module with the name ec_logger1:
05:47:04 /tmp/2025> config set ec_logger ec_logger1 Debug_Level DEBUG
For a list of all the debug levels see Table 9.28, “Debug levels”.
