| == Running OsmoMGW |
| |
| The OsmoMGW executable (`osmo-mgw`) offers the following command-line |
| arguments: |
| |
| === SYNOPSIS |
| |
| *osmo-mgw* [-h|-V] [-D] [-c 'CONFIGFILE'] [-s] |
| |
| === OPTIONS |
| |
| *-h, --help*:: |
| Print a short help message about the supported options |
| *-V, --version*:: |
| Print the compile-time version number of the program |
| *-D, --daemonize*:: |
| Fork the process as a daemon into background. |
| *-c, --config-file 'CONFIGFILE'*:: |
| Specify the file and path name of the configuration file to be |
| used. If none is specified, use `osmo-mgw.cfg` in the current |
| working directory. |
| *-s, --disable-color*:: |
| Disable colors for logging to stderr. This has mostly been |
| deprecated by VTY based logging configuration, see <<logging>> |
| for more information. |
| |
| |
| === Configure limits |
| |
| When servicing hundreds of media endpoints, it may be necessary to adjust the |
| operating system's limit on open file descriptors for the osmo-mgw process. A |
| typical default limit imposed by operating systems is 1024; this would be |
| exceeded by, for example, about 256 active voice calls with 4 RTP/RTPC ports |
| each, sockets for other interfaces not considered yet. |
| |
| It should be ok to set an OS limit on open file descriptors as high as 65536 |
| for osmo-mgw, which practically rules out failure from running out of file |
| descriptors anywhere (<16,000 active calls). |
| |
| When using systemd, the file descriptor limit may be adjusted in the service |
| file by the `LimitNOFILE` setting ("Number of Open FILE descriptors"). OsmoMGW |
| ships a systemd service file with a high LimitNOFILE setting. |
