lcfg-sysinfo - System Information
This documentation refers to lcfg-sysinfo version 1.0.0
This is an LCFG virtual component which is used to store per-host system information. It is designed to contain generic information which is not associated with any specific aspect or service (e.g. apache) on a machine.
This documentation only describes the resources available. See the "SEE ALSO" section below for details on how to query the information.
The sysinfo component has a set of resources which represent aspects of a machine covering the associated people, the operating system, and the paths to the various standard LCFG locations.
The list of resources has evolved over many years of usage within the Edinburgh University School of Informatics and as such may not include what you need, if there is something for which you would like support added then get in touch with us.
This is the hostname for the machine. The default value is taken from the value of the profile.node resource.
This is the domain for the machine. The default value is taken from the value of the profile.domain resource.
This is a string representing the manager (i.e. sysadmin) for the machine. There is no default value but this string can be set via the _ADMIN macro in an LCFG profile.
This is a string representing the user to which the machine has been allocated. There is no default value.
This is a string representing the owner for the machine. This may be the same as the allocated field but often a machine is owned by a particular organisation and allocated to an individual within that organisation. There is no default value but this string can be set via the _ORG macro in an LCFG profile.
This is a string which holds the serial number for the machine. There is no default value.
This is a string which holds the model type for the machine. There is no default value but if you also use the standard LCFG hardware headers (e.g. lcfg/hw/dell_optiplex_755.h) it will be set automatically.
This is a string which holds information on the location of the machine. There is no default value but this string can be set via the _LOCATION macro in an LCFG profile.
This is a string which can hold any comments you want to associate with the machine. There is no default value.
This string holds information on the release and version of the LCFG headers currently being used. The default value of the release part is taken from the value of the profile.release resource and the version part is taken from the LCFG_RELEASE_VERSION macro, the two parts are separated with a forward-slash.
This is a string which holds a short identification name (e.g. "sl5") for the particular distribution of the operating system being used. There is no default value but this string can be set via the OS_ID macro, if you use the standard LCFG operating-system headers (e.g. lcfg/os/sl5.h) it will be set automatically.
This is a string which holds the name (e.g. "linux") for the operating system being used. There is no default value but this string can be set via the OS_NAME macro, if you use the standard LCFG operating-system headers (e.g. lcfg/os/sl5.h) it will be set automatically.
This is a string which holds a the version (e.g. "scientific") of the operating system being used. There is no default value but this string can be set via the OS_VERSION macro, if you use the standard LCFG operating-system headers (e.g. lcfg/os/sl5.h) it will be set automatically.
This is a string which holds the version number (e.g. "5") for the particular distribution of the operating system being used. There is no default value but this string can be set via the OS_RELEASE macro, if you use the standard LCFG operating-system headers (e.g. lcfg/os/sl5.h) it will be set automatically.
This is a string which holds the architecture (e.g. i386) for the operating system being used. There is no default value but this string can be set via the ARCH_NAME macro, if you use the standard LCFG operating-system headers (e.g. lcfg/os/sl5.h) it will be set automatically.
This resource holds the list of sysinfo resources which should be displayed on the LCFG server status web pages for this particular host. The order within the list controls the order in which the resources appear on the page. Aliases can be given to improve the presentation of the short resource names. An alias should be put in front of the resource name, separated with an equals sign (=). Spaces can be created using the tilde character (~). For example, Serial~No=sno would present the value of the serial number resource with the title "Serial No". The default value for this resource is model location Serial~No=sno allocated manager owner OS=os_id Release~Version=release_version
This is an LCFG tag list with each key representing a standard LCFG path. By default the following paths are defined: lcfglib, lcfgdata, lcfgbin, lcfgsbin, lcfgcomp, lcfgvar, lcfgstatus, lcfglog, lcfglock, lcfgrotated, lcfgtmp, lcfgconf, lcfgpod, lcfgom
This resource contains the value for the path associated with a particular key. For example, sysinfo.path_lcfglib is /usr/lib/lcfg on a standard LCFG linux machine.
There is a a Perl interface for querying the LCFG system information, see LCFG::SysInfo for details. For Perl-based LCFG components it can also be queried via the GetSysInfo helper method in LCFG::Component. For shell-bashed LCFG components it can be queried via the GetSysInfo and GetSysPath functions in lcfg-ngeneric(8).
This is the list of platforms on which we have tested this software. We expect this software to work on any Unix-like platform which is supported by Perl.
