Functions

func AddForwardedCounters

func AddForwardedCounters(names []string, values []int64)

AddForwardedCounters adds the given counters on behalf of clients. Names and values must have the same length.

func ForEachLatencyCounter

func ForEachLatencyCounter(operation string, isError bool, f func(*counter.Counter))

ForEachLatencyCounter runs the provided function for each current latency counter measuring the given operation.

Exported for testing.

func Mode

func Mode() string

Mode calls x/telemetry.Mode.

func RecordClientInfo

func RecordClientInfo(params *protocol.ParamInitialize)

RecordClientInfo records gopls client info.

func RecordViewGoVersion

func RecordViewGoVersion(x int)

RecordViewGoVersion records the Go minor version number (1.x) used for a view.

func SetMode

func SetMode(mode string) error

SetMode calls x/telemetry.SetMode.

func Start

func Start()

Start starts telemetry instrumentation.

func StartLatencyTimer

func StartLatencyTimer(operation string) func(context.Context, error)

StartLatencyTimer starts a timer for the gopls operation with the given name, and returns a func to stop the timer and record the latency sample.

If the context provided to the the resulting func is done, no observation is recorded.
