Chapter 1. Admin Guide

1. Overview

The module implements RPC commands to set and get configuration variables on-the-fly, that are declared by SIP Router core and by the modules.

For example, it can be used to fine-tune values for global parameters such as debug, tcp/sctp/dns attributes, a.s.o. without the need of restart.

RPC connector modules, such as ctl or xmlrpc, although not a dependecy, should be loaded in order to execute the RPC commands exported by this module. When ctl module is loaded, the tool 'kamcmd' can be used to execute the RPC commands implemented in this module.

2. Dependencies

2.1. SIP Router Modules

The following modules must be loaded before this module:

  • No dependencies on other SIP Router modules.

2.2. External Libraries or Applications

The following libraries or applications must be installed before running SIP Router with this module loaded:

  • None.

3. RPC Interface

The module implements the RPC commands documented in the next sections.

3.1. cfg.list

cfg.list - List the configuration variables. The function has one optional parameter: group name.

Example 1.1. Use cfg.get RPC command

...
# kamcmd cfg.list
...

3.2. cfg.get

cfg.get - Get the value of a configuration variable. The function accepts two parameters: group name, variable name. The group name can optionally contain the group instance id, for example foo[5].

Example 1.2. Use cfg.get RPC command

...
# kamcmd cfg.get core debug
...

3.3. cfg.seti

cfg.seti - Set the value of a configuration variable and commit the change immediately. The function accepts three parameters: group name, variable name, integer value. The group name can optionally contain the group instance id, for example foo[5].

Example 1.3. Use cfg.seti RPC command

...
# kamcmd cfg.seti core debug 1
...

3.4. cfg.set_now_int

cfg.set_now_int - This is an alias to the command cfg.seti.

3.5. cfg.sets

cfg.sets - Set the value of a configuration variable and commit the change immediately. The function accepts three parameters: group name, variable name, string value. The group name can optionally contain the group instance id, for example foo[5].

3.6. cfg.set_now_string

cfg.set_now_string - This is an alias to the command cfg.sets.

3.7. cfg.set

cfg.set - Set the value of a configuration variable and commit the change immediately. This is a wrapper command for cfg.set_now_int and cfg.set_now_string depending on the type of the value provided. The function accepts three parameters: group name, variable name, int/string value. The group name can optionally contain the group instance id, for example foo[5].

3.8. cfg.del

cfg.del - Delete the value of a configuration variable from a group instance and commit the change immediately. The value is reset to the default value and it follows the changes of that. The function accepts two parameters: group name, variable name. The group name must contain the group instance id, for example foo[5].

3.9. cfg.set_delayed_int

cfg.set_delayed_int - Prepare the change of a configuration variable, but does not commit the new value yet. The function accepts three parameters: group name, variable name, integer value. The group name can optionally contain the group instance id, for example foo[5].

3.10. cfg.set_delayed_string

cfg.set_delayed_string - Prepare the change of a configuration variable, but does not commit the new value yet. The function accepts three parameters: group name, variable name, string value. The group name can optionally contain the group instance id, for example foo[5].

3.11. cfg.set_delayed

cfg.set_delayed - Prepare the change of a configuration variable, but does not commit the new value yet. This is a wrapper command for cfg.set_delayed_int and cfg.set_delayed_string depending on the type of the value provided. The function accepts three parameters: group name, variable name, int/string value. The group name can optionally contain the group instance id, for example foo[5].

3.12. cfg.del_delayed

cfg.del_delayed - Prepare the deletion of the value of a configuration variable from a group instance, but does not commit the change yet. The value is reset to the default value and it follows the changes of that. The function accepts two parameters: group name, variable name. The group name must contain the group instance id, for example foo[5].

3.13. cfg.commit

cfg.commit - Commit the previously prepared configuration changes. The function does not have any parameters.

3.14. cfg.rollback

cfg.rollback - Drop the prepared configuration changes. The function does not have any parameters.

3.15. cfg.help

cfg.help - Print the description of a configuration variable. The function accepts two parameters: group name, variable name.

3.16. cfg.diff

cfg.diff - List the pending configuration changes that have not been committed yet. The function does not have any parameters.

3.17. cfg.add_group_inst

cfg.add_group_inst - Add a new instance to an existing configuration group. The function accepts one parameter: group name[instance id], for example foo[5].

3.18. cfg.del_group_inst

cfg.del_group_inst - Delete an instance of an existing configuration group. The function accepts one parameter: group name[instance id], for example foo[5].
