    # Falco uses a shared buffer between the kernel and userspace to pass
    # system call information. When Falco detects that this buffer is
    # full and system calls have been dropped, it can take one or more of
    # the following actions:
    #   - ignore: do nothing (default when list of actions is empty)
    #   - log: log a DEBUG message noting that the buffer was full
    #   - alert: emit a Falco alert noting that the buffer was full
    #   - exit: exit Falco with a non-zero rc
    #
    # Notice it is not possible to ignore and log/alert messages at the same time.
    #
    # The rate at which log/alert messages are emitted is governed by a
    # token bucket. The rate corresponds to one message every 30 seconds
    # with a burst of one message (by default).
    #
    # The messages are emitted when the percentage of dropped system calls
    # with respect the number of events in the last second
    # is greater than the given threshold (a double in the range [0, 1]).
    #
    # For debugging/testing it is possible to simulate the drops using
    # the `simulate_drops: true`. In this case the threshold does not apply.

      max_burst: 1

    # Falco uses a shared buffer between the kernel and userspace to receive
    # the events (eg., system call information) in userspace.
    #
    # Anyways, the underlying libraries can also timeout for various reasons.
    # For example, there could have been issues while reading an event.
    # Or the particular event needs to be skipped.
    # Normally, it's very unlikely that Falco does not receive events consecutively.
    #
    # Falco is able to detect such uncommon situation.
    #
    # Here you can configure the maximum number of consecutive timeouts without an event
    # after which you want Falco to alert.
    # By default this value is set to 1000 consecutive timeouts without an event at all.
    # How this value maps to a time interval depends on the CPU frequency.
    syscall_event_timeouts:
      max_consecutives: 1000

    # Falco continuously monitors outputs performance. When an output channel does not allow
    # to deliver an alert within a given deadline, an error is reported indicating
    # which output is blocking notifications.
    # The timeout error will be reported to the log according to the above log_* settings.
    # Note that the notification will not be discarded from the output queue; thus,
    # output channels may indefinitely remain blocked.
    # An output timeout error indeed indicate a misconfiguration issue or I/O problems
    # that cannot be recovered by Falco and should be fixed by the user.
    #
    # The "output_timeout" value specifies the duration in milliseconds to wait before
    # considering the deadline exceed.
    #
    # With a 2000ms default, the notification consumer can block the Falco output
    # for up to 2 seconds without reaching the timeout.
    output_timeout: 2000

    # A throttling mechanism implemented as a token bucket limits the
    # rate of falco notifications. This throttling is controlled by the following configuration
    # options:
    #  - rate: the number of tokens (i.e. right to send a notification)
    #    gained per second. Defaults to 1.
    #  - max_burst: the maximum number of tokens outstanding. Defaults to 1000.
    #
    # With these defaults, falco could send up to 1000 notifications after
    # an initial quiet period, and then up to 1 notification per second
    # afterward. It would gain the full burst back after 1000 seconds of
    # no activity.
