type log_threshold = [ `All | `Src of string ] * Logs.level option
The type for log threshold. A log level of None
disables logging.
val set_level : default:Logs.level option -> log_threshold list -> unit
set_level ~default l
set the log levels needed to have all of the log sources appearing in l
be used.
val logs : log_threshold list Cmdliner.Term.t
logs
is a command-liner term for setting the log_threshold.
module Conv : sig ... end
The initial delay, specified in seconds, before a unikernel starting up. Defaults to 0. Useful for tenders and environments that take some time to bring devices up.
val at_exit : (unit -> unit Lwt.t) -> unit
at_exit hook
registers hook
, which will be executed before the unikernel exits. The first hook registered will be executed last.
at_enter_iter hook
registers hook
to be executed at the beginning of each event loop iteration. The first hook registered will be executed last.
If hook
calls at_enter_iter
recursively, the new hook will run only on the next event loop iteration.
at_leave_iter hook
registers hook
to be executed at the end of each event loop iteration. See at_enter_iter
for details.
This is mainly for for developers implementing new targets.
val run_exit_hooks : unit -> unit Lwt.t
run_exit_hooks ()
calls the sequence of hooks registered with at_exit
in sequence.
run_enter_iter_hooks ()
calls the sequence of hooks registered with at_enter_iter
in sequence.
run_leave_iter_hooks ()
call the sequence of hooks registered with at_leave_iter
in sequence.
register_arg term
registers term to be evaluated at boot time. An example is: let hello = register_arg <myterm>
(at the toplevel of the unikernel), and in the unikernel code Logs.info (fun m -> m "hello argument is: %s" (hello ()))
.
