[rrd-users] Entering historical information into RRD

[Andrew]

Hi there

I would like to record the squid access log into a rrd database 
so that I can know how much traffic was happening at any given 
time.  The problem with this is that the log entries happen 
*after* the traffic has completed -- ie. the log may indicate 
that for the last 55 minutes we were doing a long download, 
comprising 120Mb, which has nothing to do with the last 5 
minutes.  I would like this to be added to my RRD data, after the 
fact.

Before:
  |
  | x       x x               x 
  |xx     xxxxxx              x
  |xxx x xxxxxxxxxxx    x  x xxx
  +-----------------------------

After ("o" represents added data):
  | x       x x           
  |xx     xxxxxx              x 
  |xxx x xxxxxxxxxxx    x     x
  |ooooooooooooooooooooooo x xxx
  +-----------------------------

Is it possible to make this form of entry in RRD -- and if so, 
how?

&:-)


ps. Yes, I know that there are better ways of getting information 
about squid's activity -- but not per-user -- as far as I know.
