Variables

var A = Attributes

A is an alias for Attributes.

var AttributeHTTPMethod = struct {
	COPY    string
	DELETE  string
	GET     string
	HEAD    string
	OPTIONS string
	POST    string
	PUT     string
}{
	"COPY",
	"DELETE",
	"GET",
	"HEAD",
	"OPTIONS",
	"POST",
	"PUT",
}

AttributeHTTPMethod are the possible values that the attribute "http.method" can have.

var AttributeOperation = struct {
	Writes string
	Reads  string
}{
	"writes",
	"reads",
}

AttributeOperation are the possible values that the attribute "operation" can have.

var AttributeView = struct {
	TemporaryViewReads string
	ViewReads          string
}{
	"temporary_view_reads",
	"view_reads",
}

AttributeView are the possible values that the attribute "view" can have.

var Attributes = struct {
	// CouchdbNodeName (The name of the node.)
	CouchdbNodeName string
	// HTTPMethod (An HTTP request method.)
	HTTPMethod string
	// HTTPStatusCode (An HTTP status code.)
	HTTPStatusCode string
	// Operation (The operation type.)
	Operation string
	// View (The view type.)
	View string
}{
	"couchdb.node.name",
	"http.method",
	"http.status_code",
	"operation",
	"view",
}

Attributes contains the possible metric attributes that can be used.

Functions

func WithStartTime

func WithStartTime(startTime pdata.Timestamp) metricBuilderOption

WithStartTime sets startTime on the metrics builder.

Types

type MetricSettings

type MetricSettings struct {
	Enabled bool `mapstructure:"enabled"`
}

MetricSettings provides common settings for a particular metric.

type MetricsBuilder

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

MetricsBuilder provides an interface for scrapers to report metrics while taking care of all the transformations required to produce metric representation defined in metadata and user settings.

func NewMetricsBuilder

func NewMetricsBuilder(settings MetricsSettings, options ...metricBuilderOption) *MetricsBuilder

func (*MetricsBuilder) Emit

func (mb *MetricsBuilder) Emit(metrics pdata.MetricSlice)

Emit appends generated metrics to a pdata.MetricsSlice and updates the internal state to be ready for recording another set of data points. This function will be doing all transformations required to produce metric representation defined in metadata and user settings, e.g. delta/cumulative translation.

func (*MetricsBuilder) RecordCouchdbAverageRequestTimeDataPoint

func (mb *MetricsBuilder) RecordCouchdbAverageRequestTimeDataPoint(ts pdata.Timestamp, val float64)

RecordCouchdbAverageRequestTimeDataPoint adds a data point to couchdb.average_request_time metric.

func (*MetricsBuilder) RecordCouchdbDatabaseOpenDataPoint

func (mb *MetricsBuilder) RecordCouchdbDatabaseOpenDataPoint(ts pdata.Timestamp, val int64)

RecordCouchdbDatabaseOpenDataPoint adds a data point to couchdb.database.open metric.

func (*MetricsBuilder) RecordCouchdbDatabaseOperationsDataPoint

func (mb *MetricsBuilder) RecordCouchdbDatabaseOperationsDataPoint(ts pdata.Timestamp, val int64, operationAttributeValue string)

RecordCouchdbDatabaseOperationsDataPoint adds a data point to couchdb.database.operations metric.

func (*MetricsBuilder) RecordCouchdbFileDescriptorOpenDataPoint

func (mb *MetricsBuilder) RecordCouchdbFileDescriptorOpenDataPoint(ts pdata.Timestamp, val int64)

RecordCouchdbFileDescriptorOpenDataPoint adds a data point to couchdb.file_descriptor.open metric.

func (*MetricsBuilder) RecordCouchdbHttpdBulkRequestsDataPoint

func (mb *MetricsBuilder) RecordCouchdbHttpdBulkRequestsDataPoint(ts pdata.Timestamp, val int64)

RecordCouchdbHttpdBulkRequestsDataPoint adds a data point to couchdb.httpd.bulk_requests metric.

func (*MetricsBuilder) RecordCouchdbHttpdRequestsDataPoint

func (mb *MetricsBuilder) RecordCouchdbHttpdRequestsDataPoint(ts pdata.Timestamp, val int64, httpMethodAttributeValue string)

RecordCouchdbHttpdRequestsDataPoint adds a data point to couchdb.httpd.requests metric.

func (*MetricsBuilder) RecordCouchdbHttpdResponsesDataPoint

func (mb *MetricsBuilder) RecordCouchdbHttpdResponsesDataPoint(ts pdata.Timestamp, val int64, httpStatusCodeAttributeValue string)

RecordCouchdbHttpdResponsesDataPoint adds a data point to couchdb.httpd.responses metric.

func (*MetricsBuilder) RecordCouchdbHttpdViewsDataPoint

func (mb *MetricsBuilder) RecordCouchdbHttpdViewsDataPoint(ts pdata.Timestamp, val int64, viewAttributeValue string)

RecordCouchdbHttpdViewsDataPoint adds a data point to couchdb.httpd.views metric.

func (*MetricsBuilder) Reset

func (mb *MetricsBuilder) Reset(options ...metricBuilderOption)

Reset resets metrics builder to its initial state. It should be used when external metrics source is restarted, and metrics builder should update its startTime and reset it's internal state accordingly.

type MetricsSettings

type MetricsSettings struct {
	CouchdbAverageRequestTime MetricSettings `mapstructure:"couchdb.average_request_time"`
	CouchdbDatabaseOpen       MetricSettings `mapstructure:"couchdb.database.open"`
	CouchdbDatabaseOperations MetricSettings `mapstructure:"couchdb.database.operations"`
	CouchdbFileDescriptorOpen MetricSettings `mapstructure:"couchdb.file_descriptor.open"`
	CouchdbHttpdBulkRequests  MetricSettings `mapstructure:"couchdb.httpd.bulk_requests"`
	CouchdbHttpdRequests      MetricSettings `mapstructure:"couchdb.httpd.requests"`
