+=item B<CollectDelayAccounting> I<Boolean>
+
+If enabled, collect Linux Delay Accounding information for matching processes.
+Delay Accounting provides the time processes wait for the CPU to become
+available, for I/O operations to finish, for pages to be swapped in and for
+freed pages to be reclaimed. The metrics are reported as a percentage, e.g.
+C<percent-delay-cpu>. Disabled by default.
+
+This option is only available on Linux, requires the C<libmnl> library and
+requires root privileges at runtime.
