NAME

       event2vrule - adds 'events' to rrdtool graphs

SYNOPSIS

       event2vrule <params>

DESCRIPTION

       Adding Events to Graphs

       There  is a new graphing feature which allows you to specify events that should be displayed in your graphs. These events are simply a list
       of points in time at which something of interest occurred.

       For instance, one could create a plain text file in the graphs directory called events.txt containing these lines:

	 2001/02/10 1538 added support for events to FlowScan graphs
	 2001/02/12 1601 allowed the events file to be named on make command line

       Then to generate the graphs with those events included one might run:

	 $ make -f graphs.mf events=events.txt

       This feature was implemented using a new script called event2vrule that is supplied with FlowScan. This script is meant to  be  used  as  a
       ``wrapper'' for running rrdtool(1), similarly to how one might run nohup(1). E.g.:

	 $ event2vrule -h 48 events.txt rrdtool graph -s -48h ...

       That command will cause these VRULE arguments to be passed to rrdtool, at the end of the argument list:
