I'm having this problem for a long time now and tried serveral things in order to fix it but now i thought it's time to post my issue here... I have upgraded my Debian box a long time ago from squeeze to jessie. Since the upgrade it seems to me that mailgraph is not longer working : http://www.evilhannie.eu/cgi-bin/mailgraph.cgi Problem is that rrdtool is no longer creating new graphs / is not updating correctly. Would someone know what to do to resolve this ? ( RRD files arent beeing created / updated ) Oh for the record: i also have munin installed ( i have this since i had mailgraph ) ( www.evilhannie.eu/munin ) For the record 2: mailgraph worked perfectly in the past
issue is resolved. Problem was after upgrading from previous debian version ( lenny or squeez , cant rly remember ) to jessie. I had to run the config command again for mailgraph : dpkg-reconfigure mailgraph that seemed to have fixed my problems.
