[rrd-users] SUMMARY: Out of time sequence.

Hi all,

Just a quick summary on what I have got running...

The problem was that, due to a less than perfect internet connection, I 
sometimes miss data. It is possible to retrieve the data from another source 
at a later date, but it wouldn't load once the timestamps were out of 

Thanks to those who told me that this wasn't possible, and pointed out that 
I could use the route of dump -> xml, modify, restore from xml to 
incorporate changes.

So, I modified the data generation program so that it output in the same 
format as the xml dump, and then used sed to replace data entries which had 
NaN entries, and then restored the database. The only complication was that 
the data entries were timestamped every 20 minutes, and I had to mod the 
real data timestamps to conform.

The last problem that I have is that I seem to have one data point per hour, 
so loading the data this way still leaves two NaN entries for the data. 
Could someone tell me the best way of getting around this - ie what 
algorithm does the _real_ data antry interface use?

Cheers, and thanks for the support,
