John, some of the changes I made to the php were a bit ugly because I did them a while ago, and I didn't know Ganglia like I do now. If you give me a while I could extract that change (from the others I have made) and apply it to the standard ganglia PHP tree and make a patch out of it. kind Richard Grevis Infrastructure Architecture Barclays Capital, Canary Wharf, London, E14 4BB *DDI : +44 (0) 20 7773 4915 * richard.grevis > -----Original Message----- > From: john allspaw [mailto:[EMAIL PROTECTED] > Sent: 09 November 2006 03:03 > To: Grevis, Richard: IT (LDN); ganglia-general@lists.sourceforge.net > Subject: Re: [Ganglia-general] Any plans on zooming or > graphing granularitychanges to ganglia ? > > > Excellent!
