<DIV><FONT face=Arial color=#000000 size=2>Hello all</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In my setup I have one program writing to my rrd files</FONT></DIV>
<DIV><FONT face=Arial size=2>using rrdtool executable.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have, until now, only had one program reading my rrd files</FONT></DIV>
<DIV><FONT face=Arial size=2>using rrdgraph.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We are, in the future going to also use CGI to run rrtdump</FONT></DIV>
<DIV><FONT face=Arial size=2>on the rrd files.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It is likely that the 2 processes will try to read the same</FONT></DIV>
<DIV><FONT face=Arial size=2>file at the same time (eventually)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do I need to worry about multiple readers? Do I need</FONT></DIV>
<DIV><FONT face=Arial size=2>to implement some sort of reader lock external to the</FONT></DIV>
<DIV><FONT face=Arial size=2>rrd tool processes?</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
