Windows 2008R2 Drives in TB & PB don't graph correctly

Can you please look at the ss_host_disk.php from current svn (branches/0.8.7h) and let us know if this issue is already resolved. Somehow, I am thinking that it's not adequate, but wanted to check.

The fix in branches/0.8.7 is wrong. It says:

Code: Select all

                        if($snmp_data<0){
                                        return (abs($snmp_data) + 2147483647) * $sau;
                        } else {
                                        return $snmp_data * $sau;
                        }

The correct way to fix the value is to add 2**32, i.e.

Code: Select all

                        if($snmp_data<0){
                                        return ($snmp_data + 4294967296) * $sau;
                        } else {
                                        return $snmp_data * $sau;
                        }

That's just how two's complement arithmetic works.

Can you please install the hmib plugin and perform an audit for me?

Unfortunately I can't.

I'm using the stock Cacti 0.8.7e from Ubuntu 10.04 - it doesn't have the PIA installed, and my colleague tells me that if you try to apply the PIA patches you get merge conflicts with Debian's local changes to Cacti. So this would entail a full reinstall of Cacti from source.

[TheWitness]

You would not have to reinstall the whole package. Just audit the global.php and config.php. You would have to move a few things from config.php.dist to /etc/cacti/debian.php as well. My test boxes are Debian and run the PIA just fine.
