colplot - plots collectl data using gnuplot SYNOPSIS
colplot -plot plots [-switches] DESCRIPTIONS
Generate the plots selected by PLOT(s) on either the terminal, a file or delivered as email. The switches control the files to plot, the timeframes, formats and destinations. In the case of a web based display, you can run in `live` mode which will provide for periodic screen refreshes for viewing real-time data. See the web-based help and FAQ for more detail. PLOTS
The plots themselves are selected from the standard list (see -showplots) with -plot. -plot List one or more plot names either separated with commas and no whitespace or if you want to include whitespace be sure to enclose the string in quotes. SWITCHES
The remainder of the switches which are all optional fall into several categories, the first being those that select the files and time- frames to plot and are as follow: -dir Look in this directory for plot files rather than the one pointed to by PlotDir in colplot.conf. A plot file is one with a known extension and a properly formatted name. Any files that fail either of these tests will be ignored. -contains string1 [string2...] This field consists of one or more strings separated by commas or whitespace (if whitespace the entire string must be quoted). Each selected plot file has its name compared to each string. Unless -any is specified, each string must appear somewhere in that file name for it to continue to be selected. As a special case, if there is a string containing a [, it is assumed to be in pdsh format, a compact format for specifying multiple hostnames, eg xyz[1-5,10] specifies 6 hosts whose names all begin with xyz and are followed by one of 6 values. In this case, only files with hostnames exactly matching these names will be selected. -all If specified all strings specified by -contains must match for a file to be seleceted for plotting. -date from[-thru] The starting and ending date between which files are selected for plotting. The dates must be in yyyymmdd format. -time from[-thru] The starting and ending time between which data is plotted. The times must be in hh:mm OR hh:mm:ss format. The hour portion may be 1 or 2 digits. The next set of switches control which plots are actually displayed -filters string1 [string2...] These only apply to detail plots. They select which devices to produce plots for. Invalid or unknown devics are ignored. In other words, if one selects "-filters eth xyz d1" and requests network plots, only ethernet devices will be displayed. Since 'xyz' is an invalid selection string it is ignored. Since there are no network devices with 'd1' in their names, it too will be ignored. If one choses network and disk plots, ethernet devices as well as any disk names with a 'd1' in them will be displayed. -type type By default, plots are geneated using solid lines. However, one can request a different format be used including points or stacked line or stacked points. -unique If one generates multiple unique plot files per day via the -ou switch in collectl, those files will be ignored by colplot. This switch, currently only available via the CLI will cause those files to be selected and displayed in the same plot. The next set of switches deal with plot formatting, typically only used under unusual circumstances since the default formats meet most needs: -adjust Colplot uses a default height for the vertical axis which can be overridden via -height. However sometimes a plot is not high enough for all the labels to fit in the legend. This switch will keep the user specified height for all plots in which the legend fits as a single column but increase the heights of those that aren't high enough. -filetype type This switch must be used in conjunction with selecting a destination other than the terminal, specifically email or directory. One can use it to change the default from a PDF file to either a PNG file for each plot or TTY to send PNG output for one plot to STD- OUT. -height number This controls the vertical hight of a plot. This width also includes the xaxis and you can therefore increase the room taken by a single plot by choosing -noxaxis. -nolegend number This removes the legend from the plotting area, causing the plot to become physically wider. -noxaxis This removed the xaxis from the plotting area, causing the plot to become physically taller. -thick number For some people the thickness of the lines in a plot may be too thin to clearly see the different color variations of the lines. Versions of gnuplot >= 4.2 support wider lines and therefore so does colplot. If using scatter plots, a different plotting symbol is actually used. Values of 2 or 3 are usually sufficient. -width number This switch controls the width of a plot where 1 is the size of a printable page. If set to more than 1 and either -file or -mail is chosen it will be forced to 1. By setting this number to less than 1, it may be possible to fit more than one plot on a page or screen. As this width also includes the legend, you can further reduce the plot size by choosing -nolegend. -xtics n This causes a tic mark to be drawn on the xaxis every n seconds. It usually doesn't make sense unless you've chosen a fairly narrow timeframe in which to generate a plot. -ylog Make the y-axis logrithmic. This set of switches deal with the plot destination when it is NOT the terminal window: -email address Linux only. Address to send plot file(s) to. The only syntax check is for an '@' to appear somewhere in the address string. -filedir directory The name of directory into which the plot file(s) will be placed. The directory must exist. -href Print the hrefs that would be used if run from a browser. -incctl Really only intended for users familiar with gnuplot, this is the control file used to generate the plots. It allows someone to manually edit the file to change the plot appearance and/or labels by rerunning gnuplot using its settings. -pagbrk Instead of generating a page break in a pdf file whenever a page fills, this flag will cause a page break whenever the hostname changes. -subject subject Use this subject in email rather than the default. And finally for completeness there are several types of help: -help Standard help. -showparams This is really a debugging aid, intended for developers and/or people building custom plot definitions. When specified, the plot- ting parameters for each selected plot will be shown. Of particular value is the actual column number for each data element in each selected file. -showplots List the names of all the standard plots available for use with the -plots switch. -version Show both the versions of both colplot as well as gnuplot.
