It's snmp, a utility installed on most systems.
It can collect the metrics you are after, but the formatting of output (Disk Space % and "averages")
would have to be coded by you or supplied by another script.
package supplies sar and some other utilities that may provide the input you seek.
Zabbix, I love it but it does NOT do any
zabbix has the ability to collect snmp data as well as zabbix-agent data.
I installed JasperServer
and I use iReport locally to query my zabbix db on the zabbix server.
There is a Community Edition that's Free and supported by the "community".
There is paid support that I suspect is pretty expensive but it doesn't cover the Community Edition.
The formatting (PDF, HTML, .csv etc....) output required by the "Manager" can be provided by the Jasperserver product or
iReport can do this also, but it is quite time-intensive. (at least for me it is)
Out of the box solutions for reporting (snmp) data, you may wish to check out
Seems Icinga (a fork of Nagios) does reporting...https://en.wikipedia.org/wiki/Icinga..._.26_Reporting
Sorry, I wish I had a stock package or solution for you.

snmp collection can be automated via scripting and is quite easy once the client-server communication is configured correctly.
Again, however, the reporting would have to be something managed at your "end" of the stream (after collection).
Other valid options may exist and some other answers provided by other members here may prove useful.
