sysinfo [-a] [-c] [-d] [-h] [-i] [-v [level]] module ...


The sysinfo utility is a shell script, the purpose of which is to automatically gather system information and document the hardware and software configuration of the given host system running
.Fx .

The goal is to provide a system operator with descriptive information about an unknown
.Fx installation.

The following options are available:
-a Display complete system information, i.e. run all the available modules. See below.
-c Toggle colorful output (useful when using less or redirecting the output to a file).
-d Toggle debug messages.
-h Display usage information.
-i Toggle info messages.
-v [level] Set the verbose level. Supported values are 0 and 1. The verbose level will be set to 1 if no argument is specified. The default is 0 (no verbose output).
module Display the system information related to the specified subsystem type. All of the specified modules will be run. It is possible to use a short form of a module in order to run it. This means that an input of sy will match the system module, however an input of s would result in an error as it matches both storage and system modules. The following modules are currently supported:
bios BIOS information. It is required to install the dmidecode(8) tool in order to obtain this information. It will provide you with information such as BIOS version and release date as well as BIOS vendor.
cpu CPU details, such as total number of cores, number of cores per CPU, CPU speed as well as its features, its type, architecuture, etc.
mem System memory details. This module provides information related to physical memory and SWAP usage; lists wired, active, inactive, cached and free memory statistics.
misc Miscellaneous information. Currently provides information about system crontab, current time and date and statistics about open files.
network Provides a detailed information about network subsystem. It summarizes configuration for each network device in the system and displays firewall, routing, resolver and socket information.
os Operating system details mostly related to release version, kernel version, scheduler, process statistics, information about running processes and jails.
  Information about installed packages, such as its number, how many of them are outdated and which have known security vulnerabilities (in this case it is required to have the portaudit(1) tool installed on the system.
  Information about system services. Lists running and not running services, detects services which are supposed to be running and are not. Lists the listening IP sockets opened by individual services as well as user under which the given service is running as well as the command by which this service was started.
storage Details about storage subsystem. Summarizes information about available RAID controllers and hard drives, their size and features. Lists existing and mounted file systems, exported file systems through NFS and prints disk usage and I/O statistics.
system System information (hardware related), mainly CD-ROM and graphics card information. In case the dmidecode(8) tool is available, it lists the Manufacturer of the given machine and provides some information about base board.
user User related information; this include information about currently logged-in users, members of the wheel group, number of local users and groups. This module also provides some statistics about logged-in time about users and lists last login date for each user.

The features of sysinfo include:

  • Automatically gathers various system information related to the hardware and software configuration of the
    .Fx host system.
  • The tool optionally provides useful hints and references to material containing detailed information about provided report. These messages are prefixed by the INFO: string.
  • The tool is also capable to detect some missing configuration or dangerous settings, in which case it prints a warning prefixed by the WARNING: string.
  • Easy to customize. Making use of several shell scripts and one configuration file it is possible to easily extend already implemnted modules as well as add new ones.

Please check the sysinfo.conf(5) manual page for configuration options.
