MI (management interface) functions which are exported by OpenSIPS core.

1. arg

Returns the full list of arguments used when OpenSIPS was started. As in UNIX, the first argument is the name of executable binary.
Arguments: none
Output: an array with multiple strings representing the arguments.

Example of usage:

    # opensips-cli -x mi arg
    [
        "./opensips",
        "-f",
        "/etc/openser/test.cfg"
    ]

2. kill

The command will terminate OpenSIPS (and internal shutdown).
Arguments: none
Output: none

Examples of usage:

    # opensips-cli -x mi kill

3. list_blacklists

The command lists all the defined (static or learned) blacklists from OpenSIPS.
Arguments: none
Output: an array with each object describing the list (name, owner, flags); the "Rules" item is an array with each object member describing the rules (blacklists) for each list (IP/mask, protocol, port, matching regexp, flags).

Examples of usage:

    # opensips-cli -x mi list_blacklists

4. list_tcp_conns

The command lists all ongoing TCP/TLS connection from OpenSIPS.
Arguments: none
Output: an array with one object per connection with the following attributes : ID, type, state, source, destination, lifetime, alias port.

Examples of usage:

    # opensips-cli -x mi list_tcp_conns

5. log_level [level] [pid]

Get or set the logging level of one or all OpenSIPS processes. If no argument is passed to the log_level command, it will print a table with the current logging levels of all processes. If a logging level is given, it will be set for each process. If pid is also given, the logging level will change only for that process.
Arguments:

Examples of usage:

    # opensips-cli -x mi log_level
    {
        "Processes": [
            {

                "Type": "MI FIFO"
            },
            {
                "PID": 10673,
                "Log level": 1,
                "Type": "SIP receiver udp:193.268.3.233:5060"
            },
        ]
    }
    # opensipsctl fifo log_level 1
    {
        "New global log level": 1
    }
    # opensipsctl fifo log_level 4 10670

8. reload_routes

Triggers the reload of the routing block (the routes) from the script during the runtime. Arguments: none
Output: none

Please note that there are some limitations of when a reload is possible or not. Depending on the initial configuration of your modules, the reload may be rejected as the usage of the functions in the new script is not compatible with the original module setting and initialization.
If the reload fails, take a look at the logs to understand why - it may have been a syntax error or maybe a module related constraint. Anyhow, if the reload fails, there is no impact on your running OpenSIPS.

    # opensips-cli -x mi uptime
{
    "Now": "Mon Jul 21 17:41:03 2008",
    "Up since": "Mon Jul 21 17:36:33 2008",
    "Up time": "270 [sec]"
}

10. version

Arguments: none
Output: one item (named "Server") containing the version string.
