Hi Luca

I have recently updated to the latest version of the ntop package in Debian.
I got this bug report. Do you know what that problem could be?

Best regards,

// Ola

Hi,

After upgrading ntop to 3:3.3-4, the rrdPlugin (activated by default) is
not usable anymore. Some functionnality (Network Load for example) are
broken due to this. I tried a fresh install (on amd64), the problem is
the same.

Here is the information I had when launching ntop (or reactavating the
rrdPlugin) in the syslog.

Thanks for maintening ntop
