Re: [one-users] ganglia integration and base64 errors
Since version 3.8 the output of poll pushed to ganglia is compressed using zlib before being encoded in base 64.

Re: [one-users] Ganglia integration
Hello Olivier, Thanks for this feedback. My request wasn't clear enough, I already monitor my hosts and I see the OPENNEBULA-VMS-INFORMATION variable in Ganglia, but I don't know how to use it to provide graphs on the VM usage. Will the VM information be displayed in Sunstone ? In Ganglia ? Any help is welcome on this.
