Types ¶
type DiagnosticsService ¶
type DiagnosticsService struct {
// contains filtered or unexported fields
}
DiagnosticsService gathers Go runtime, memory, and garbage-collector statistics for the diagnostics endpoints. It holds no external dependencies; WebSocket metrics and worker-goroutine counts are merged in at the handler layer to avoid an import cycle with the api/ws package.
func NewDiagnosticsService ¶
func NewDiagnosticsService() *DiagnosticsService
NewDiagnosticsService returns a DiagnosticsService. startedAt is captured at construction (≈ process start) and used to report uptime.
func (*DiagnosticsService) Collect ¶
func (s *DiagnosticsService) Collect() (system.RuntimeInfo, system.MemoryInfo, system.GCInfo)
Collect samples the current runtime, memory, and GC state.
LeakedGoroutines is the last-known leak count from the runtime; it does not trigger a leak-detection GC. Use ScanGoroutineLeaks for a fresh scan.
func (*DiagnosticsService) ScanGoroutineLeaks ¶ added in v2.9.0
func (s *DiagnosticsService) ScanGoroutineLeaks() (system.GoroutineLeakReport, error)
ScanGoroutineLeaks runs a leak-detection GC and returns the leaked-goroutine pprof text (debug=1). debug=2 would dump every goroutine, not only leaks.
