hist_net_test(1)
NAME
hist_net_test - Calculate a histogram from the net performance weekly
data files
SYNOPSIS
hist_net_test |
[Option [...]] DataRoot
{HistFile, -} SrcHost
DestHost |
DESCRIPTION
The script hist_net_test calculates a histogram from net performance
weekly data files.
The histogram will be calculated for the connection from SrcHost to
DestHost.
Both hosts may be specified with the host titles or (IP) addresses.
The connection between both hosts may be one-directional or two-directional.
The histograms can be calculated for the throughput values and for the minimum,
average, maximum or lost round-trip values.
It is also possible to add a previously obtained histogram file to the histogram
to be calculated.
Th histogram can be calculated as a function from the following attributes:
- The weeks.
- The days in the week.
- The hours in the day.
The histogram output file, HistFile, is in the format of a
gnuplot(1) data file.
Therefore, it contains the following fields:
BinMean BinCount BinWidth
OPTIONS
The following options can be specified:
- -add_hist {HistFile, -}
- Add the histogram data from the histogram file HistFile or from
Standard Input to the histogram to be calculated.
This option may be multiple specified.
- -bin_size BinSize
- Set the bin size.
The default is: 1.
- -hour MinHour[-MaxHour]
- Set the hour of the day interval.
This option may be multiple specified.
Default all hours are added to the histogram.
- -net_type {Inet, QoS}
- Specify the net type.
The default is: Inet.
- -no_perc
- Do not print percentages but bin counts.
The default is to print bin counts.
- -no_print
- Do not print the values to be added to the histogram bins.
This is the default.
- -no_symm_conn
- Use the connection between both hosts not symmetric (i.e. in one direction.
- This is the default.
- -perc
- Do not print percentages but bin counts.
- This is the default.
- -ping_type {min, avg, max, lost}
- Specify the ping type.
The default is: avg.
- -print
- Print the values to be added to the histogram bins to
Standard Error in the format:
Date WeekDay Hour
Value SrcHost DestHost
Default the values are not printed.
- -symm_conn
- Use the connection between both hosts symmetric (i.e. in two directions).
Default there is not a symmetric connection.
- -test_type {ping, throughput}
- Set the test type to determine the histogram from.
The default test type is: throughput.
- -threshold Threshold
- Set the threshold for a bin count to be accepted.
The default is: 0.
- -week MinWeek[-MaxWeek]
- Set the week interval.
This option may be multiple specified.
Default all available weeks are added to the histogram.
- -week_day
MinWeekDay[-MaxWeekDay]
- Set the day of the week ([0-6]) interval.
This option may be multiple specified.
Default all available weeks are added to the histogram.
