<DIV><FONT face=Arial color=#000000 size=2>I am upgrading to the 2.28 (from a very old version) and I see that</FONT></DIV>
<DIV><FONT face=Arial size=2>the DEF statement not has start and end time specifications.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would like to use this to generate multiple MAXIMUM over different time periods </FONT></DIV>
<DIV><FONT face=Arial size=2>using PRINT and one call to rrd graph.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For intance: </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I save a statistic in several differend RRAs in one RRDFILE.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I want the MAXIMUM value over the last 3 hours, the last 24 hours etc.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It looks like I could, in the def commands specify something like</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>DEF:stat3hours=/rrddir/rrdfil:stat:AVERAGE:step=blah:start=<now-3hours>:end=<now></FONT></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>DEF:stat24hours=/rrddir/rrdfil:stat:AVERAGE:step=blah:start=<now-24hours>:end=<now></FONT></DIV></FONT></DIV>
<DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then use the following VDEFS</FONT></DIV>
<DIV><FONT face=Arial size=2>VDEF:stat3hoursMax=stat3hours,MAXIMUM</FONT></DIV>
<DIV><FONT face=Arial size=2>VDEF:stat24hoursMat=stat24hours,MAXIMUM</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then the PRINT statements</FONT></DIV>
<DIV><FONT face=Arial size=2>PRINT:stat3hoursMax:"3 hour MAX: %8.4lf"</FONT></DIV>
<DIV><FONT face=Arial size=2>PRINT:stat24hoursMax:"24 hour MAX: %8.4lf"</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My questions are</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>0. Can I request different start/end times for the same DS in multiple DEF statements in one command?</FONT></DIV>
<DIV><FONT face=Arial size=2>1. If so, do I need to specify a start and end time for the as an argument to the graph command?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
