Command History
Usage Guidelines A histogram is a collection of statistics sampled over time on a burst-by-burst basis and presented as a
function of bins.
The data for the histogram is collected as soon as the command succeeds and continues until either the
specification is deleted using the no option, or the specified duration expires. The collected data is
printed out to the console at user-specified intervals.
A histogram statistic is created when data is sampled for every burst. For each sampled burst, the count
in a specific bin is incremented.
Note There should be no measurable impact or degradation of router performance from running
histograms. Cisco recommends that you keep the number of histograms that you are
running simultaneously to a minimum, and that you terminate any histograms no longer
needed.
Note Histograms and timelines share the same DSP memory. A total of 10 histograms and
timelines can be created on a single DSP. There are a total of 8 locations for fine
histograms and timelines and 5 locations for coarse histograms. The combination of
histograms and timelines must be less than 10.
average Specifies histogram samples that should be the average of the burst
data over all the frequencies.
number toneVal Specifies that a particular tone in the burst should be used to report
the histogram data.
update interval Specifies how often, in seconds, the collected data is printed on the
screen.
sum Specifies whether to add the data at every update.
width coarse | fine Specifies the histogram resolution. Coarse is 50 bins and fine is 12
bins.
