[rrd-users] Bulk updating rrd - how???

[John Goor]

When I have the following script:

# RRD DEFAULTS
my $start       = "1022925300"; # When should the database start?
my $dsn         = "data";       # DataSourceName
my $dst         = "ABSOLUTE";   # DataSourceType
my $min         = "U";          # What is the minimum value accepted?
my $max         = "U";          # What is the maximum value accepted?
my $int         = 300;

RRDs::create   ($rrd, "--start", "$start",
                "DS:$dsn:$dst:$int:$min:$max",
                "RRA:AVERAGE:0.5:1:10");

The next problems and questions arise:
- when i fetch the database, 295 lines show up.
I expect 10 lines however (for 10 samples are specified in the RRA)
- I want the db to start at the time specified, 1022925300 because the data
I enter starts at 1022925600.
When I use RRDs::fetch (the script from the tutorial),1031863200 shows up
as the last date and 1031776500 as the first.

There should be a way to bulk-update isn't there?
I did a post earlier, got a reply, tried to follow the instructions but did
not succeed.

My assumption is the next:
when I create a database and I have already data waiting, I must be able to
fill the rrd with the history-data to achief relevant statistics
immediately and don't have to wait 1 week to get a last week's average. I
don't understand why this should'n be supported, so I expect someone can
help me.

Thanks in advance!
Regards,
John

P.S.
I'd appreciate if anyone could give me some sample lines which will prove
my assumption to be true.



Can someone help me?
