PROGRAM:

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:
