[rrd-users] non-sequential updates?

[Chris Majewski]

Is it possible to do non-sequential updates?

For example,  the database ifInput.168.rrd stores a  counter of octets
flowing into interface 168 of my router.
The data  is collected via SNMP  by Sun NetManager and  stored in text
files.

Somebody  comes  along  and wants  to  see  a  graph of  traffic  into
interface 168 over the course of April 15th, 2002.

I have a script that will
  * read the file data/2002-04/15/ifInput.168.Z
  * update ifInput.168.rrd
  * generate the graph using the newly acquired data
  * feed the graph to a webpage

So far so good. Now somebody else comes along and wants to see a graph
for April 8th, 2002. My script bombs with an error of this form:

ERROR: illegal attempt to update using time 1016265372 when last update time is 1018680995 (minimum one second step)
