PoliceAction

The PoliceAction class supports policing.

class PoliceAction(action_index: Optional[int] = None, *, rate: Optional[int] = None, burst: Optional[int] = None, mtu: Optional[int] = None, decision: ActionDecision, overhead: Optional[int] = None)

This class supports the tc(8) police action as documented in tc-police(8).

Parameters:

• action_index – an integer that effectively names the action

• rate – rate

• burst – burst

• mtu – MTU

• decision – control action to take

• overhead – overhead

classmethod get_kind() → str

Returns police

get_rate() → Optional[int]

Returns the rate

get_burst() → Optional[int]

Returns the burst

get_mtu() → Optional[int]

Returns the mtu

get_overhead() → Optional[int]

Returns the overhead

action_creation_args() → List[str]

Returns a list of tc(8) arguments to instantiate this action

get_action_index() → Optional[int]

Returns the action index

get_decision() → Optional[ActionDecision]

Returns the decision (e.g. ActionDecision.DROP) for this action

get_install_duration() → int

Returns the number of seconds since the action was installed (created)

get_stats() → Optional[ActionStats]

Returns action statistics

get_use_duration() → int

It is not clear how the use duration (in seconds) is defined. As a data point, the install duration and use duration of an action created as part of a filter creation always have the same value.

parse_common_lines(line_iter: LineGroupIterator) → None

Parse lines common to all actions. Stop when an empty line is encountered (the end of the action)

set_action_index(action_index: int) → None

Sets the action index

set_durations(*, install_duration: int, use_duration: int) → None

Set the install and use duration
