Methods
export
▸ export(): Promise<string>
Return a serialized representation of the logger that can be used to start subspans in other places. See Span.start_span for more details.
Returns
Promise<string>
Implementation of
flush
▸ flush(): Promise<void>
Returns
Promise<void>
log
▸ log(event, options?): PromiseUnless<IsAsyncFlush, string>
Log a single event. The event will be batched and uploaded behind the scenes if logOptions.asyncFlush is true.
Parameters
| Name | Type | Description |
|---|---|---|
event | Readonly<StartSpanEventArgs> | The event to log. |
options? | Object | Additional logging options |
options.allowConcurrentWithSpans? | boolean | in rare cases where you need to log at the top level separately from spans on the logger elsewhere, set this to true. :returns: The id of the logged event. |
Returns
PromiseUnless<IsAsyncFlush, string>
logFeedback
▸ logFeedback(event): void
Log feedback to an event. Feedback is used to save feedback scores, set an expected value, or add a comment.
Parameters
| Name | Type |
|---|---|
event | LogFeedbackFullArgs |
Returns
void
startSpan
▸ startSpan(args?): Span
Lower-level alternative to traced. This allows you to start a span yourself, and can be useful in situations
where you cannot use callbacks. However, spans started with startSpan will not be marked as the "current span",
so currentSpan() and traced() will be no-ops. If you want to mark a span as current, use traced instead.
See traced for full details.
Parameters
| Name | Type |
|---|---|
args? | StartSpanArgs |
Returns
traced
▸ traced<R>(callback, args?): PromiseUnless<IsAsyncFlush, R>
Create a new toplevel span underneath the logger. The name defaults to "root".
See Span.traced for full details.
Type parameters
| Name |
|---|
R |
Parameters
| Name | Type |
|---|---|
callback | (span: Span) => R |
args? | StartSpanArgs & SetCurrentArg |
Returns
PromiseUnless<IsAsyncFlush, R>
