Types ¶
type MetricType ¶
type MetricType string
const ( //MetricRequestSizeBytes MetricType = "request_size_bytes" // MetricRequestSizeBytes is the request size in bytes //MetricRequestDurationSeconds MetricType = "request_duration_seconds" // MetricRequestDurationSeconds is the request duration in seconds //MetricRequestsTotal MetricType = "requests_total" // MetricRequestsTotal is the total number of requests //MetricRequestsSlowTotal MetricType = "requests_slow_total" // MetricRequestsSlowTotal is the total number of slow requests //MetricRequestsInFlight MetricType = "requests_in_flight" // MetricRequestsInFlight is the number of requests in flight //MetricResponseSizeBytes MetricType = "response_size_bytes" // MetricResponseSizeBytes is the response size in bytes //MetricErrorsTotal MetricType = "errors_total" // MetricErrorsTotal is the total number of errors //MetricEvent MetricType = "event" // MetricEvent is the event //MetricSiteEvent MetricType = "site_event" // MetricSiteEvent is the site event //MetricSummaryLatency MetricType = "summary_latency" // MetricSummaryLatency is the summary latency MetricUptime MetricType = "uptime" MetricRequestsTotal MetricType = "requests_total" MetricRequestsDurationSeconds MetricType = "requests_duration_seconds" MetricRequestsInFlight MetricType = "requests_in_flight" MetricRequestsSlowTotal MetricType = "requests_slow_total" MetricCounterSendBytes MetricType = "counter_send_bytes" MetricCounterRecvBytes MetricType = "counter_recv_bytes" MetricHistogramLatency MetricType = "histogram_latency" MetricSummaryLatency MetricType = "summary_latency" MetricCounterException MetricType = "counter_exception" MetricCounterEvent MetricType = "counter_event" MetricCounterSiteEvent MetricType = "counter_site_event" )
func (MetricType) String ¶
func (m MetricType) String() string
type Metrics ¶
type Metrics interface {
Enabled() bool // Enabled returns whether metrics is enabled
Disable()
Observe(ctx context.Context, reporter Report)
Log(ctx context.Context, handler, method, code string, sendBytes, recvBytes, latency int64)
}
Metrics is the metrics interface for metrics
type Recorder ¶
type Recorder interface {
RequestTotal(module, handler, method, code string)
CounterSendBytes(module, handler, method, code string, length int64)
CounterRecvBytes(module, handler, method, code string, length int64)
RequestDurationSeconds(module, handler, method string, latency int64)
SummaryLatencyLog(module, handler, method string, latency int64)
CounterException(module, errors string)
CounterEvent(module, event string)
CounterSiteEvent(module, event, site string)
RequestsInFlight(module, state string, value int64)
}
Recorder is an interface for recording various metrics.
