Functions

func LogEvent

func LogEvent(event *models.AlertCurEvent, location string, err ...error)

Types

type Consumer

type Consumer struct {
	// contains filtered or unexported fields
}

func NewConsumer

func NewConsumer(alerting aconf.Alerting, ctx *ctx.Context, dispatch *Dispatch) *Consumer

创建一个 Consumer 实例

func (*Consumer) LoopConsume

func (e *Consumer) LoopConsume()

type Dispatch

type Dispatch struct {
	RwLock sync.RWMutex
	// contains filtered or unexported fields
}

func NewDispatch

func NewDispatch(alertRuleCache *memsto.AlertRuleCacheType, userCache *memsto.UserCacheType, userGroupCache *memsto.UserGroupCacheType,
	alertSubscribeCache *memsto.AlertSubscribeCacheType, targetCache *memsto.TargetCacheType, notifyConfigCache *memsto.NotifyConfigCacheType,
	alerting aconf.Alerting, ctx *ctx.Context) *Dispatch

创建一个 Notify 实例

func (*Dispatch) HandleEventNotify

func (e *Dispatch) HandleEventNotify(event *models.AlertCurEvent, isSubscribe bool)

HandleEventNotify 处理event事件的主逻辑 event: 告警/恢复事件 isSubscribe: 告警事件是否由subscribe的配置产生

func (*Dispatch) ReloadTpls

func (e *Dispatch) ReloadTpls() error

func (*Dispatch) Send

func (e *Dispatch) Send(rule *models.AlertRule, event *models.AlertCurEvent, notifyTarget *NotifyTarget, isSubscribe bool)

type Notice

type Notice struct {
	Event *models.AlertCurEvent `json:"event"`
	Tpls  map[string]string     `json:"tpls"`
}

type NotifyChannels

type NotifyChannels map[string]bool

NotifyChannels channelKey -> bool

func NewNotifyChannels

func NewNotifyChannels(channels []string) NotifyChannels

func (NotifyChannels) AndMerge

func (nc NotifyChannels) AndMerge(other NotifyChannels)

func (NotifyChannels) OrMerge

func (nc NotifyChannels) OrMerge(other NotifyChannels)

type NotifyTarget

type NotifyTarget struct {
	// contains filtered or unexported fields
}

NotifyTarget 维护所有需要发送的目标 用户-通道/回调/钩子信息,用map维护的数据结构具有去重功能

func EventCallbacksDispatch

func EventCallbacksDispatch(rule *models.AlertRule, event *models.AlertCurEvent, prev *NotifyTarget, dispatch *Dispatch) *NotifyTarget

func GlobalWebhookDispatch

func GlobalWebhookDispatch(rule *models.AlertRule, event *models.AlertCurEvent, prev *NotifyTarget, dispatch *Dispatch) *NotifyTarget

func NewNotifyTarget

func NewNotifyTarget() *NotifyTarget

func NotifyGroupDispatch

func NotifyGroupDispatch(rule *models.AlertRule, event *models.AlertCurEvent, prev *NotifyTarget, dispatch *Dispatch) *NotifyTarget

GroupDispatch 处理告警规则的组订阅关系

func (*NotifyTarget) AndMerge

func (s *NotifyTarget) AndMerge(other *NotifyTarget)

AndMerge 将 channelMap 中的 bool 值按照 and 的逻辑进行合并,可以单独将人/通道维度的通知移除 常用的场景有: 1. 人员离职了不需要发送告警了 2. 某个告警通道进行维护,暂时不需要发送告警了 3. 业务值班的重定向逻辑，将高等级的告警额外发送给应急人员等 可以结合业务需求自己实现router

func (*NotifyTarget) OrMerge

func (s *NotifyTarget) OrMerge(other *NotifyTarget)

OrMerge 将 channelMap 按照 or 的方式合并,方便实现多种组合的策略,比如根据某个 tag 进行路由等

func (*NotifyTarget) ToCallbackList

func (s *NotifyTarget) ToCallbackList() []string

func (*NotifyTarget) ToChannelUserMap

func (s *NotifyTarget) ToChannelUserMap() map[string][]int64

ToChannelUserMap userMap(map[uid][channel]bool) 转换为 map[channel][]uid 的结构

func (*NotifyTarget) ToWebhookList

func (s *NotifyTarget) ToWebhookList() []*models.Webhook

type NotifyTargetDispatch

type NotifyTargetDispatch func(rule *models.AlertRule, event *models.AlertCurEvent, prev *NotifyTarget, dispatch *Dispatch) *NotifyTarget

Dispatch 抽象由告警事件到信息接收者的路由策略 rule: 告警规则 event: 告警事件 prev: 前一次路由结果, Dispatch 的实现可以直接修改 prev, 也可以返回一个新的 NotifyTarget 用于 AndMerge/OrMerge
