Struct State 

pub struct State {

    pub status: Status,
    pub since: u64,
    pub fails: u32,
    pub oks: u32,
    pub failing_since: Option<u64>,
    pub notified: Status,
    pub down_since: Option<u64>,
    pub downs: Vec<u64>,
    pub flapping: bool,
    pub cert_warned: Option<u64>,
    pub first_check: Option<u64>,
    pub never_up: bool,
    pub stopped: bool,
}

A monitor’s state, kept across daemon restarts so a restart never sends a down (or an up) twice.

Fields

status: Status

since: u64

Unix milliseconds the status began.

fails: u32

Failed checks in a row.

oks: u32

Successful checks in a row.

failing_since: Option<u64>

When the current run of failures began.

notified: Status

What channels were last told.

down_since: Option<u64>

When the incident channels were told about began.

downs: Vec<u64>

Unix milliseconds of recent downs, for flap damping.

flapping: bool

cert_warned: Option<u64>

The certificate (by its expiry, unix seconds) already warned about.

first_check: Option<u64>

When the first check of a pending monitor ran.

never_up: bool

Pending for NEVER_UP_MS with only failures.

stopped: bool

Its app or stack service is scaled to 0, since State::since.

Implementations

impl State

pub fn observe(&mut self, ok: bool, now: u64, t: Thresholds) -> Step

Take one check’s result at now (unix milliseconds).

pub fn stop(&mut self, now: u64) -> bool

Its target was scaled to 0 at now: forget the run it was on, so starting again waits for the first success like a new monitor. Returns whether it was not stopped already.

pub fn reset_counts(&mut self)

Start counting afresh (a resumed or edited monitor), keeping what channels were told.

Trait Implementations

impl Clone for State

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for State

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for State

where State: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for State

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for State

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
