A ramdisk to report the hardware of a machine to an inventory service.

This will collect up some basic information about the hardware it
|
|
|
|
|
boots on:
|
|
|
|
|
|
|
|
|
|
* CPU cores
|
|
|
|
|
* RAM
|
|
|
|
|
* Disk
|
|
|
|
|
* NIC mac address
|
|
|
|
|
|
|
|
|
|
This information will then be collated into a JSON document, base64
|
|
|
|
|
encoded and passed, via HTTP POST, to a URL that you must specify on
|
|
|
|
|
the kernel commandline, thus:
|
|
|
|
|
|
|
|
|
|
HW_DISCOVERY_URL=http://1.2.3.4:56/hw_script.asp
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This is currently fairly fragile as there can be a huge variability in
|
|
|
|
|
the number of disks/NICs in servers and how they are configured.
|
|
|
|
|
|
|
|
|
|
If other elements wish to inject data into the hardware discovery data,
|
|
|
|
|
they can - they should be specified before hwdiscovery to the image
|
|
|
|
|
building script, and they should contain something like this in their
|
|
|
|
|
init fragment:
|
|
|
|
|
|
|
|
|
|
_vendor_hwdiscovery_data="$_vendor_hwdiscovery_data
|
|
|
|
|
\"some vendor key\" : \"some data you care about\",
|
|
|
|
|
\"some other vendor key\" : \"some other data you care about\","
|
|
|
|
|
|
|
|
|
|
Note that you are essentially feeding JSON into the main hwdiscovery
|
|
|
|
|
JSON.
|
|
|
|
|
|
|
|
|
|
This will allow any number of vendor specific hwdiscovery elements to
|
|
|
|
|
chain together their JSON fragments and maintain consistency.
