Chapter 1. Admin Guide

1.1. Overview

This module implements a xmlrpc server that handles xmlrpc requests and generates xmlrpc responses. When a xmlrpc message is received a default method is executed.

At first, it looks up the MI command. If found it parses the called procedure's parameters into a MI tree and the command is executed. A MI reply tree is returned that is formatted back in xmlrpc. The response is built in two ways - like a string that contains the MI tree nodes information (name, values and attributes) or like an array whose elements are consisted of each MI tree node stored information.

1.2. Dependencies

1.2.1. External Libraries or Applications

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

  • libxml2

1.2.2. OpenSIPS Modules

The following modules must be loaded before this module:

  • httpd module.

1.3. Exported Parameters

1.3.1. http_root(string)

Specifies the root path for xmlrpc requests: http://[opensips_IP]:[opensips_httpd_port]/[http_root]

The default value is "RPC2".

Example 1.1. Set http_root parameter

...
modparam("mi_xmlrpc_ng", "http_root", "opensips_mi_xmlrpc")
...

1.3.2. trace_destination (string)

Trace destination as defined in the tracing module. Currently the only tracing module is proto_hep. This is where traced mi messages will go.

WARNING: A tracing module must be loaded in order for this parameter to work. (for example proto_hep).

Default value is none(not defined).

Example 1.2. Set trace_destination parameter

...
modparam("proto_hep", "trace_destination", "[hep_dest]10.0.0.2;transport=tcp;version=3")

modparam("mi_xmlrpc_ng", "trace_destination", "hep_dest")
...

1.3.3. trace_bwlist (string)

Filter traced mi commands based on a blacklist or a whitelist. trace_destination must be defined for this parameter to have any purpose. Whitelists can be defined using 'w' or 'W', blacklists using 'b' or 'B'. The type is separate by the actual blacklist by ':'. The mi commands in the list must be separated by ','.

Defining a blacklists means all the commands that are not blacklisted will be traced. Defining a whitelist means all the commands that are not whitelisted will not be traced. WARNING: One can't define both a whitelist and a blacklist. Only one of them is allowed. Defining the parameter a second time will just overwrite the first one.

WARNING: A tracing module must be loaded in order for this parameter to work. (for example proto_hep).

Default value is none(not defined).

Example 1.3. Set trace_destination parameter

...
## blacklist ps and which mi commands
## all the other commands shall be traced
modparam("mi_xmlrpc_ng", "trace_bwlist", "b: ps, which")
...
## allow only sip_trace mi command
## all the other commands will not be traced
modparam("mi_xmlrpc_ng", "trace_bwlist", "w: sip_trace")
...

1.4. Exported Functions

No function exported to be used from configuration file.

1.5. Known issues

Commands with large responses (like ul_dump) will fail if the configured size of the httpd buffer is to small (or if there isn't enough pkg memory configured).

Future realeases of the httpd and mi_xmlrpc_ng modules will address this issue.

1.6. Example

This is an example showing the xmlrpc format for the get_statistics net: shmem: MI commad: response.

(2) including any documentation-related commits, excluding merge commits. Regarding imported patches/code, we do our best to count the work on behalf of the proper owner, as per the "fix_authors" and "mod_renames" arrays in opensips/doc/build-contrib.sh. If you identify any patches/commits which do not get properly attributed to you, please submit a pull request which extends "fix_authors" and/or "mod_renames".

(3) ignoring whitespace edits, renamed files and auto-generated files
