Functions

func GetFetchImpByDb

func GetFetchImpByDb(db string) iEvalMatchFetch

func ListAllResources

func ListAllResources(manager modulebase.Manager, params *jsonutils.JSONDict) ([]jsonutils.JSONObject, error)

Types

type AlertEvaluator

type AlertEvaluator interface {
	Eval(reducedValue *float64) bool
	String() string
}

AlertEvaluator evaluates the reduced value of a timeserie. Returning true if a timeseries is violating the condition ex: ThresholdEvaluator, NoValueEvaluator, RangeEvaluator

func NewAlertEvaluator

func NewAlertEvaluator(cond *monitor.Condition) (AlertEvaluator, error)

NewAlertEvaluator is a factory function for returning an `AlertEvaluator` depending on the input condition.

type AlertQuery

type AlertQuery struct {
	Model        monitor.MetricQuery
	DataSourceId string
	From         string
	To           string
}

AlertQuery contains information about what datasource a query should be send to and the query object.

type FormatCond

type FormatCond struct {
	QueryMeta    *tsdb.QueryResultMeta
	QueryKeyInfo string
	Reducer      string
	Evaluator    AlertEvaluator
}

func (FormatCond) String

func (c FormatCond) String() string

type MetricQueryCondition

type MetricQueryCondition struct {
	QueryCons     []QueryCondition
	HandleRequest tsdb.HandleRequestFunc
}

func NewMetricQueryCondition

func NewMetricQueryCondition(models []*monitor.AlertCondition) (*MetricQueryCondition, error)

func (*MetricQueryCondition) ExecuteQuery

func (query *MetricQueryCondition) ExecuteQuery() (*mq.Metrics, error)

type NoDataQueryCondition

type NoDataQueryCondition struct {
	*QueryCondition
}

func (*NoDataQueryCondition) Eval

func (c *NoDataQueryCondition) Eval(context *alerting.EvalContext) (*alerting.ConditionResult, error)

func (*NoDataQueryCondition) NewNoDataEvalMatch

func (c *NoDataQueryCondition) NewNoDataEvalMatch(context *alerting.EvalContext, host jsonutils.JSONObject) (*monitor.EvalMatch, error)

type QueryCondition

type QueryCondition struct {
	Index         int
	Query         AlertQuery
	Reducer       Reducer
	Evaluator     AlertEvaluator
	Operator      string
	HandleRequest tsdb.HandleRequestFunc
	ResType       string
}

QueryCondition is responsible for issue and query. reduce the timeseries into single values and evaluate if they are firing or not.

func (*QueryCondition) Eval

func (c *QueryCondition) Eval(context *alerting.EvalContext) (*alerting.ConditionResult, error)

Eval evaluates te `QueryCondition`.

func (*QueryCondition) FetchCustomizeEvalMatch

func (c *QueryCondition) FetchCustomizeEvalMatch(context *alerting.EvalContext, evalMatch *monitor.EvalMatch,
	alertDetails *monitor.CommonAlertMetricDetails)

func (*QueryCondition) FillSerieByResourceField

func (c *QueryCondition) FillSerieByResourceField(resource jsonutils.JSONObject,
	series *tsdb.TimeSeries)

func (*QueryCondition) GenerateFormatCond
