[rrd-users] Data Change Script available ?

[Ralf Kruedewagen]

Hi RRDTool community,

I am wondering if anybody has already written a script that can be 
used to update past data within a RRDTool database. I want to change 
data that has already written to the DB.

My idea:
1) Dump RRD database to XML file ("rrdtool dump")
2) Edit XML File (change past data)
3) Restore RRD database from XML file ("rrdtool restore")

Nice would be, if the script could be used on a webserver. That would 
mean that I need for step 2 some input fields like

- Choose RRD database
- Choose timestamp(start and end)
- Choose DS to be replaced
- Choose value to replace

Best would be if RRDTool would support something like "rrdtool change 
filename timestamp:value1:" ;-)

Best Regards
Ralf
