The web page error states "[ERROR: opening '_public/aquaph.rrd': No such file or directory] I have tried both of the following however still seems to place an underscore ( _ ) in the path to my rrd <FORM><INPUT NAME=RRD_NAME TYPE=RADIO VALUE=/public/aquaph>rrdname1, <FORM><INPUT NAME=RRD_NAME TYPE=RADIO VALUE=public/aquaph>rrdname1, ######WEB PAGE######## HEAD> RRDCGI Example Page for /website/ph1d /public/aquaph Selection trend name, rrdname1, Graph [ERROR: opening '_public/aquaph.rrd': No such file or directory] ###CGI FILE #### #!/opt/bin/rrdcgi <HTML> HEAD><TITLE>RRDCGI Demo</TITLE></HEAD> <BODY> <H1>RRDCGI Example Page for <RRD::CV png_NAME> <RRD::CV RRD_NAME></H1> <H2>Selection</H2> <FORM><INPUT NAME=png_NAME TYPE=RADIO VALUE=/website/ph1d> trend name, <FORM><INPUT NAME=RRD_NAME TYPE=RADIO VALUE=/public/aquaph>rrdname1, <INPUT TYPE=SUBMIT></FORM> <H2>Graph</H2> <P> <RRD::GRAPH <RRD::CV::PATH png_NAME>.png --title "Temperatures for "<RRD::CV::QUOTE RRD_NAME> DEF:phv=<RRD::CV::PATH RRD_NAME>.rrd:ph:AVERAGE LINE2:phv#00a000:"ph value"> </P> </BODY> </HTML> ----- Original Message ----- From: "Matt" <[EMAIL PROTECTED]> To: <rrd-users@list.ee.ethz.ch> Sent: Thursday, November 09, 2006 7:07 AM Subject: [rrd-users] Re: Who is using RRDTool with a NSLU2 "SLUG" > Rob, your problem really isn't an RRDTOOL issue, it's a web server issue. > You need your web server to spawn an external command, either (preferably) > via php, or perhaps a shell command. > > Have you tried asking on irc #openslug ? > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Rob Conway > Sent: Wednesday, 8 November 2006 10:45 PM > To: rrd-users@list.ee.ethz.ch > Subject: [rrd-users] Re: Who is using RRDTool with a NSLU2 "SLUG" > > I am using rrdtool - 1.2.14-1 which I upgraded to yesterday.
