Types ¶
type EfficientBuffer ¶ added in v0.13.0
type EfficientBuffer []byte
func (*EfficientBuffer) PutInt16 ¶ added in v0.13.0
func (eb *EfficientBuffer) PutInt16(v int16)
PutInt16 writes the passed int16 in little endian and advances the current slice.
func (*EfficientBuffer) PutUint16 ¶ added in v0.13.0
func (eb *EfficientBuffer) PutUint16(v uint16)
PutUint16 writes the passed uint16 in little endian and advances the current slice.
func (*EfficientBuffer) PutUint32 ¶ added in v0.13.0
func (eb *EfficientBuffer) PutUint32(v uint32)
PutUint32 writes the passed uint32 in little endian and advances the current slice.
func (*EfficientBuffer) PutUint64 ¶ added in v0.13.0
func (eb *EfficientBuffer) PutUint64(v uint64)
PutUint64 writes the passed uint64 in little endian and advances the current slice.
func (*EfficientBuffer) PutUint8 ¶ added in v0.13.0
func (eb *EfficientBuffer) PutUint8(v uint8)
PutUint8 writes the passed uint8 in little endian and advances the current slice.
func (*EfficientBuffer) Slice ¶ added in v0.13.0
func (eb *EfficientBuffer) Slice(size int) EfficientBuffer
Slice returns a slice re-sliced from the original EfficientBuffer. This is useful to efficiently write byte by byte, for example, when setting BPF maps without incurring in extra allocations in the writing methods, or changing the capacity of the underlying memory buffer.
Callers are responsible to ensure that there is enough capacity left for the passed size.
type FileStore ¶ added in v0.20.0
type FileStore struct {
// contains filtered or unexported fields
}
FileStore writes profiles to a local file.
func NewFileStore ¶ added in v0.20.0
NewFileStore creates a new FileProfileWriter.
type NoopProfiler ¶ added in v0.10.0
type NoopProfiler struct{}
NoopProfiler does nothing. It serves as a skeleton of what other will have to be implemented when adding a new profiler.
func (*NoopProfiler) LastError ¶ added in v0.10.0
func (p *NoopProfiler) LastError() error
func (*NoopProfiler) LastProfileStartedAt ¶ added in v0.10.0
func (p *NoopProfiler) LastProfileStartedAt() time.Time
func (*NoopProfiler) Name ¶ added in v0.10.0
func (p *NoopProfiler) Name() string
func (*NoopProfiler) ProcessLastErrors ¶ added in v0.10.0
func (p *NoopProfiler) ProcessLastErrors() map[int]error
func (*NoopProfiler) Stop ¶ added in v0.10.0
func (p *NoopProfiler) Stop()
type PID ¶ added in v0.10.0
type PID int32
PID is the process ID of the profiling target. See https://ftp.gnu.org/old-gnu/Manuals/glibc-2.2.3/html_node/libc_554.html
type ProcessInfoManager ¶ added in v0.20.0
type ProcessInfoManager interface {
Fetch(ctx context.Context, pid int) (process.Info, error)
FetchWithFreshMappings(ctx context.Context, pid int) (process.Info, error)
Info(ctx context.Context, pid int) (process.Info, error)
}
TODO: Unify PID types.
type ProfileStore ¶ added in v0.20.0
type ProfileStore interface {
Store(ctx context.Context, labels model.LabelSet, wrt profile.Writer, executableInfo []*profilestorepb.ExecutableInfo) error
}
type RemoteStore ¶ added in v0.20.0
type RemoteStore struct {
// contains filtered or unexported fields
}
RemoteStore is a profile writer that writes profiles to a remote profile store.
func NewRemoteStore ¶ added in v0.20.0
func NewRemoteStore(logger log.Logger, profileStoreClient profilestorepb.ProfileStoreServiceClient) *RemoteStore
NewRemoteStore creates a new RemoteProfileWriter.
func (*RemoteStore) Store ¶ added in v0.20.0
func (rw *RemoteStore) Store(ctx context.Context, labels model.LabelSet, prof profile.Writer, ei []*profilestorepb.ExecutableInfo) error
Store sends the profile using the designated write client.
