I'm glad to see that you're making some progress on your homework assignment from what you originally showed us four days ago on the thread titled "Trouble with Iterators and Hashtables (Java)". But it looks very much like you're posting homework problems to the "Programming" forum rather than to the "Homework & Coursework Questions" forum. That makes it much less likely that we're going to spend much time trying to understand your code and help you help you complete your assignments.

event2vrule
EVENT2VRULE(1) General Commands Manual EVENT2VRULE(1)
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:
