it would vary by the vendor (or distro...), and so there's not really a one size fits all approach to give. Top and Vmstat might offer some insight, but again they're not present on all systems...so you're going to need to roll your own.

dpkg::vendor
Dpkg::Vendor(3) libdpkg-perl Dpkg::Vendor(3)
NAME
Dpkg::Vendor - get access to some vendor specific information
DESCRIPTION
The files in /etc/dpkg/origins/ can provide information about various vendors who are providing Debian packages. Currently those files look
like this:
Vendor: Debian
Vendor-URL: http://www.debian.org/
Bugs: debbugs://bugs.debian.org
The file should be named according to the vendor name.
FUNCTIONS
$fields = Dpkg::Vendor::get_vendor_info($name)
Returns a Dpkg::Control object with the information parsed from the corresponding vendor file in /etc/dpkg/origins/. If $name is
omitted, it will use /etc/dpkg/origins/default which is supposed to be a symlink to the vendor of the currently installed operating
system. Returns undef if there's no file for the given vendor.
$name = Dpkg::Vendor::get_vendor_file($name)
Check if there's a file for the given vendor and returns its name.
$name = Dpkg::Vendor::get_current_vendor()
Returns the name of the current vendor. If DEB_VENDOR is set, it uses that first, otherwise it falls back to parsing
/etc/dpkg/origins/default. If that file doesn't exist, it returns undef.
$object = Dpkg::Vendor::get_vendor_object($name)
Return the Dpkg::Vendor::* object of the corresponding vendor. If $name is omitted, return the object of the current vendor. If no
vendor can be identified, then return the Dpkg::Vendor::Default object.
Dpkg::Vendor::run_vendor_hook($hookid, @params)
Run a hook implemented by the current vendor object.
