	"log"

	"cloud.google.com/go/errorreporting"
	"golang.org/x/net/context"
)

func main() {
	// Create the client.
	ctx := context.Background()
	ec, err := errorreporting.NewClient(ctx, "my-gcp-project", errorreporting.Config{
		ServiceName:    "myservice",
		ServiceVersion: "v1.0",
	})
	defer func() {
		if err := ec.Close(); err != nil {
			log.Printf("failed to report errors to Stackdriver: %v", err)
		}
	}()

	// Report an error.
	err = doSomething()

		})
	}
}

func doSomething() error {
	return errors.New("something went wrong")
}

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client represents a Google Cloud Error Reporting client.

func NewClient

func NewClient(ctx context.Context, projectID string, cfg Config, opts ...option.ClientOption) (*Client, error)

NewClient returns a new error reporting client. Generally you will want to create a client on program initialization and use it through the lifetime of the process.

func (*Client) Close

func (c *Client) Close() error

Close closes any resources held by the client. Close should be called when the client is no longer needed. It need not be called at program exit.

func (*Client) Flush

func (c *Client) Flush()

Flush blocks until all currently buffered error reports are sent.

If any errors occurred since the last call to Flush, or the creation of the client if this is the first call, then Flush report the error via the (*Client).OnError handler.

func (*Client) Report

func (c *Client) Report(e Entry)

Report writes an error report. It doesn't block. Errors in writing the error report can be handled via Client.OnError.

func (*Client) ReportSync

func (c *Client) ReportSync(ctx context.Context, e Entry) error

ReportSync writes an error report. It blocks until the entry is written.

type Config

type Config struct {
	// ServiceName identifies the running program and is included in the error reports.
	// Optional.
	ServiceName string

	// ServiceVersion identifies the version of the running program and is
	// included in the error reports.
	// Optional.
	ServiceVersion string

	// OnError is the function to call if any background
	// tasks errored. By default, errors are logged.
	OnError func(err error)
}

Config is additional configuration for Client.

type Entry

type Entry struct {
	Error error
	Req   *http.Request // if error is associated with a request.
	Stack []byte        // if user does not provide a stack trace, runtime.Stack will be called
}

Entry holds information about the reported error.
