cfetool create - Set up a new Database
SYNOPSIS
cfetool create name [--path⎪-p directory name] [--step⎪-s step]
[--daily⎪-d] [--weekly⎪-w] [--yearly⎪-y] [--cfenvd⎪-c] [--his‐
tograms⎪-H] [--verbose⎪-v] [--file⎪-f filename] [--help⎪-h]
DESCRIPTION
Creates a new database and, optionally, histogram file in a new direc‐
tory with the name given. If the -p option is specified, it will be
created as a subdirectory of the path given. Otherwise, it will be a
subdirectory of the current working directory.
The -d, -w, and -y options specify the period over which the data will
span, and may be combined to create multiple databases. If they are all
ommitted, the default is weekly.
OPTIONS
--path⎪-p
The directory in which to create the new database folder. If this
argument is not provided, the current working directory will be
used.
--step⎪-s
The interval, in minutes, with which the database will be updated.
If this argument is not provided, cfetool assumes a default of 5
minutes.
--daily⎪-d
Create a database for recording daily patterns.
--weekly⎪-w
Create a database for recording weekly patterns.
--yearly⎪-y
Create a database for recording yearly patterns.
--cfenvd⎪-c
Communicate with cfengine. If this option is specified, cfetool
will set classes understandable by cfagent. For more information,
see the cfenvd documentation.
--histograms⎪-H
Create a histogram file, to store information about the probability
distribiution of fluctuations about the mean value over all times
of day. Cfetool won't write anything to this file for the first
four weeks, as it has to have reliable mean values in order to
accurately calculate it.
--verbose⎪-v
Print details of the command's execution to the standard output
stream.
--file⎪-f
Specifies a file which contains measurements to feed into the data‐
base in batch mode. Used for testing purposes. Each line in the
file should be in either of these formats:
month/day/year hour:min:sec value
or
epoch value
--help⎪-h
Prints a short help message and then exits.
EXAMPLE
% cfetool create temperature --path /my/path --histograms --step 10
Creates an empty database and histogram file in /my/path/temperature/,
ready to store values over ten minute intervals spanning a one-week
period.
