Alex, <br><br>Thanks for getting back to me. <br><br>These are actually rates. It is a CPU utilization rate. These values are point in time. So, at 2/3/03 11:00 CPU utilization is at 10%<br>Does that help for clarification?<br>

</div></div>What do these numbers mean?<br>
When were they valid?<br>
<br>
<br>
RRDtool is not a graphing program. Use e.g. gnuplot for that.<br>
<br>
If these numbers are rates, you still need to know when these rates<br>
were valid. For instance: "12", does this mean a rate between<br>
"2/3/03 11:00" and "2/3/03 11:01" or between<br>
"2/3/03 11:01" and "2/3/03 11:02"? A small but significant difference.<br>
RRDtool uses end times (thus: updating for 2/3/03 11:01 is updating the<br>
interval upto and including 2/3/03 11:01).<br>
<br>
Are these times in some local time or in UTC? If they are in local time,<br>
make sure to compensate for this and don't forget about daylight saving<br>
(if any).<br>
<br>
You will need to convert each pair into <timestamp>:<value>, and then<br>
give those as input to rrdtool. This is a *very* basic operation, so<br>
perhaps you need to explain the problem you encounter a bit more.<br>
