Types ¶
type Report ¶
type Report struct {
Timestamp time.Time `json:"timestamp"`
WindowStart time.Time `json:"window_start"`
WindowEnd time.Time `json:"window_end"`
SLOs []SLOStatus `json:"slos"`
Overall bool `json:"overall_compliant"`
}
Report represents a full SLA status report.
type SLAConfig ¶
type SLAConfig struct {
// SLOs is the list of SLOs to track.
SLOs []SLO `json:"slos"`
// WindowDuration is the rolling window over which SLIs are calculated.
WindowDuration time.Duration `json:"window_duration"`
}
SLAConfig configures the SLA monitor.
func DefaultConfig ¶
func DefaultConfig() SLAConfig
DefaultConfig returns a default SLA config with standard SLOs.
type SLAMonitor ¶
type SLAMonitor struct {
// contains filtered or unexported fields
}
SLAMonitor tracks SLIs and computes SLO compliance and error budgets.
func NewSLAMonitor ¶
func NewSLAMonitor(cfg SLAConfig) *SLAMonitor
NewSLAMonitor creates a new SLAMonitor with the given config.
func (*SLAMonitor) Handler ¶
func (m *SLAMonitor) Handler() http.HandlerFunc
Handler returns an HTTP handler that serves the SLA status as JSON at GET /api/sla/status.
func (*SLAMonitor) RecordLatency ¶
func (m *SLAMonitor) RecordLatency(d time.Duration)
RecordLatency records a request latency.
func (*SLAMonitor) RecordRequest ¶
func (m *SLAMonitor) RecordRequest(isError bool)
RecordRequest records a request outcome.
func (*SLAMonitor) RecordUptime ¶
func (m *SLAMonitor) RecordUptime(success bool)
RecordUptime records an uptime check result.
func (*SLAMonitor) Reset ¶
func (m *SLAMonitor) Reset()
Reset clears all SLI data and resets the window start time.
func (*SLAMonitor) Status ¶
func (m *SLAMonitor) Status() Report
Status computes the current SLA status report.
type SLO ¶
type SLO struct {
// Name is a human-readable name for this SLO.
Name string `json:"name"`
// Type is "uptime", "latency", or "error_rate".
Type string `json:"type"`
// Target is the target value (e.g., 0.999 for 99.9% uptime, 500 for 500ms latency).
Target float64 `json:"target"`
}
SLO defines a Service Level Objective.
type SLOStatus ¶
type SLOStatus struct {
Name string `json:"name"`
Type string `json:"type"`
Target float64 `json:"target"`
Current float64 `json:"current"`
Met bool `json:"met"`
ErrorBudget float64 `json:"error_budget"`
ErrorBudgetUsed float64 `json:"error_budget_used"`
}
SLOStatus represents the status of a single SLO.
