Chapter 1. Admin Guide

1.1. Overview

This module provides an HTTP transport layer implementation for OpenSIPS's Management Interface.

1.2. To-do

Features to be added in the future:

  • possibility to authenticate connections.

1.3. Dependencies

1.3.1. OpenSIPS Modules

The following modules must be loaded before this module:

  • httpd module.

1.4. Exported Parameters

1.4.1. mi_http_root(string)

Specifies the root path for mi http requests. The link to the mi web interface must be constructed using the following patern: http://[opensips_IP]:[opensips_mi_port]/[mi_http_root]

The default value is "mi".

Example 1.1. Set mi_http_root parameter

...
modparam("mi_http", "mi_http_root", "opensips_mi")
...

1.4.2. mi_http_method(integer)

Specifies the HTTP request method to be used:

  • 0 - use GET HTTP request

  • 1 - use POST HTTP request

The default value is 0.

Example 1.2. Set mi_http_method parameter

...
modparam("mi_http", "mi_http_method", 1)
...

1.4.3. 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 1.3. Set trace_destination parameter

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

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

1.4.4. 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 1.4. Set trace_destination parameter

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

1.5. Exported Functions

No function exported to be used from configuration file.

1.6. 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_httpd modules will address this issue.
