The hasys program is used to collect a pre-defined set of system infor‐
mation from the local host. The collected information is used to update
a local RAP database or dumped to the standard output if -n option is
The set of information collected by hasys is defined in an ASCII schema
file specified by the -f option and has the default value
schema/hasys.sch. Each line in the schema file represents a single
attribute and my have one or more values associated with it.
Attributes other than resource type and version number are used to
determine the type of information to be reported by hasys. A given
pieces of information will not be collected or reported if the associ‐
ated attribute is commented out with # or remove from the schema file.
Note that attributes resource type and version number are part of every
schema file and should not be removed or commented out. A schema file
will be rejected if one or more essential attributes are missing or the
value associated with the version number does not match that of hasys.
hasys can be used to generate a fresh schema file using the -g option.
The system information reported by hasys is defined in the file
hasys.sch as follows:
IP address(s) for the local host
Aliases if any.
Work station or server.
number of CPUs
Type of operating system running on local host.
physical memory (bytes)
Size, in bytes, of physical memory installed on local host.

-L Tells hasys that any logging information should be written to
the default application logfile - this file is named hasys.log ,
and will be located in the applogs subdirectory of your Net‐
Worker installation directory. Only one of -L or -l may be spec‐
ified - not both. If neither -L or -l is specified in the argu‐
ments to hasys then any logging information will be printed on
stdout and stderr.
-l log file
Allows you to specify the name of the file that hasys will write
its log to. Only one of -L or -l may be specified - not both. If
neither -L or -l is specified in the arguments to hasys then any
logging information will be printed on stdout and stderr.
-n Dump the collected information to the standard output; do not
update the local RAP database.
-g Generate a new schema file for hasys after renaming the old
schema, if exists, to <name>.<date>.[1..]
-h Display a brief help message; ignore all other options.
-v Run in verbose mode.
