Functions ¶
func GetVTraceLevel ¶
SetVTraceLevel returns the vtrace level This value is used to determine which log messages are sent as part of the vtrace output.
Types ¶
type Logger ¶ added in v0.1.10
type Logger struct{}
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store implements a store for traces. The idea is to keep all the information we have about some subset of traces that pass through the server. For now we just implement an LRU cache, so the least recently started/finished/annotated traces expire after some maximum trace count is reached. TODO(mattr): LRU is the wrong policy in the long term, we should try to keep some diverse set of traces and allow users to specifically tell us to capture a specific trace. LRU will work OK for many testing scenarios and low volume applications.
func NewStore ¶
func NewStore(opts flags.VtraceFlags) (*Store, error)
NewStore creates a new store according to the passed in opts.
func (*Store) TraceRecord ¶
func (s *Store) TraceRecord(id uniqueid.Id) *vtrace.TraceRecord
TraceRecord returns a TraceRecord for a given Id. Returns nil if the given id is not present.
func (*Store) TraceRecords ¶
func (s *Store) TraceRecords() []vtrace.TraceRecord
TraceRecords returns TraceRecords for all traces saved in the store.
