Could somebody please explain in layman terms some of these components?
I have simple data:
a date and a number (time mail went out, and seconds for it to return)
What I did was collect this data for a couple weeks. Today, I set utc_start
to equal 0 hr of today. I have no idea what to set for counter or average
(ie., should I use 600, 200, etc.) I also have no idea what to set for
average (1200, 1000000, 5, etc.). I need some explaination so I logically
put in the right numbers. I just wanted a graph showing today's data to
whatever time I run the script. The script uses 0 hr utc time and gets the
time that the script is run and converts that to utc time too.
rrdtool create mailmon.rrd --start $utc_start DS:delivery:COUNTER:600:U:U
When I create the graph, I used:
rrdtool graph mailmon.gif --width 360 --vertical-label seconds --start
$start --end $last DEF:delivery=mailmon.rrd:delivery:AV
I set start to utc 0 hr today and set end to the last utc time of my data.
The graph shows on the horizontal week as a measure. I did not expect that
at all. I was expecting 0 hr of the present date to whatever time I ran
the script. I see M as a measure on the vertical. No idea what that is.
Please pelase help!
