[rrd-users] Time issue with graphs

[Dirk Bulinckx]

Hi,

I'll start by introducing myself.  I'm the author of an Win32 based
network monitoring tool called Servers Alive.  We just started adding
RRDTool logging to Servers Alive and are seeing a problem with it.

Servers Alive is logging to the RRDTool "database", however the graphs
only show a start of the logging one hour later then the time at which
we started.

Example:
	started logging at 10:10AM
	graph shows entries from 11:10AM on.
Example of an UPDATE that was done at 12:03PM:
	C:\data\RRD\src\tool_release\rrdtool.exe update
c:\data\rrd\database\sa_1.rrd 1067947382:1.6

Graph is created with the following command:
C:\data\RRD\src\tool_release\rrdtool.exe graph  hour_sa_1.gif -s -3600
--title="Telenet gateway" DEF:sa_1=sa_1.rrd:roundtrip:MAX
LINE1:sa_1#0000FF:"Response Time"

Database creaed with the following command:
C:\data\RRD\src\tool_release\rrdtool.exe create
c:\data\rrd\database\sa_1.rrd -s 10 DS:roundtrip:GAUGE:720:U:U
RRA:MAX:0.5:1:720

(we add a new sample every 10 seconds in this example)


Any ideas?
