I wonder if it does not like you using the same name in you DEF for inlet as well as the name of the data set (DS)...
Maybe that is why you are not getting the legend as well !! -----Original Message----- From: Oliver Cook [mailto:[EMAIL PROTECTED] Sent: Thursday, February 15, 2001 9:17 AM To: Nikolaos Abatzis Cc: [email protected] Subject: Re: [rrd-users] GAUGE graphs (router memory) Dear Nikolaos, Thanks for your response. However, it's not the timeframe that I think is the problem. After all, as you say, the default is 24 hours, and that was the data I showed from the "rrdtool fetch..." I tried it with "-s -86400" just to force it but that didn't change anything. Thanks for your input though! I hope I can find out how to do this!
