Steve,<br><br>Thank you for your reply. I followed your steps and am successfully running 1 minute intervals, with only 1 switch though. I am having issues with adding additional switches with the rrd configuration. Can someone please check my setup steps and let me know what I am missing or needs changed to setup 2 switches to work with the rrd tool? I believe something needs changed with the 14all.cgi or mrtg-conf.cgi but not exactly sure.<br>

<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">To use 1-min polling, you need to:<br>
1. have the cron job every 1 min, or else use daemon mode<br>
2. have Interval:1 in the cfg files<br>
3. re-create your .rrd or .log files, if you are changing from a 5min configuration<br>
<br>
If it is not working, then can you be more precise about what is not working? Give some example graph images and so on...<br>

<b>Subject:</b> [mrtg] 1 minute polling interval<br>
</font><br>
</div><div class="im">
<div></div>
<div>I have been trying to change the polling interval to one minute and not having any luck with the latest version of MRTG. I changed the chron interval and also tried to follow the 1Min MRTG patch steps with absolutely no luck:
<a href="http://www.loplop.net/projects/1minMRTG/" target="_blank">http://www.loplop.net/projects/1minMRTG/</a>. Is there any documentation that is easy to follow to setup 1 minute polling? I was able to setup the RRDTool with my MRTG installation in Debian
along with changing the chron interval, but have had absolutely no luck past this point. Any help will be appreciated.<br>
<br>
Thanks! </div>
