Functions ¶
func NewHandler ¶
func NewHandler(collectors ...NamedCollector) http.Handler
NewHandler returns an HTTP handler that gathers metrics from the provided NamedCollectors. Each collector is wrapped with tracing and the request context (if supported).
Types ¶
type ContextAwareCollector ¶
type ContextAwareCollector interface {
prometheus.Collector
WithContext(ctx context.Context) NamedCollector
}
ContextAwareCollector allows injecting context into a wrapped collector.
type HTTPMetricsCollector ¶
type HTTPMetricsCollector struct {
// contains filtered or unexported fields
}
HTTPMetricsCollector implements NamedCollector and integrates OpenTelemetry HTTP metrics with the existing Prometheus metrics infrastructure.
func NewHTTPMetricsCollector ¶
func NewHTTPMetricsCollector(ctx context.Context, _ *config.Config, serviceName string, log logrus.FieldLogger) *HTTPMetricsCollector
NewHTTPMetricsCollector creates a new HTTPMetricsCollector that integrates OpenTelemetry HTTP metrics with Prometheus. It initializes the OpenTelemetry meter provider and creates a Prometheus exporter for metrics collection.
func (*HTTPMetricsCollector) Collect ¶
func (c *HTTPMetricsCollector) Collect(ch chan<- prometheus.Metric)
Collect forwards the Collect call to the OpenTelemetry Prometheus registry
func (*HTTPMetricsCollector) Describe ¶
func (c *HTTPMetricsCollector) Describe(ch chan<- *prometheus.Desc)
Describe forwards the Describe call to the OpenTelemetry Prometheus registry
func (*HTTPMetricsCollector) MetricsName ¶
func (c *HTTPMetricsCollector) MetricsName() string
MetricsName returns the name of this collector for tracing purposes
func (*HTTPMetricsCollector) Shutdown ¶
func (c *HTTPMetricsCollector) Shutdown() error
Shutdown gracefully shuts down the OpenTelemetry meter provider
type NamedCollector ¶
type NamedCollector interface {
prometheus.Collector
MetricsName() string
}
NamedCollector is a Prometheus collector that also exposes a consistent name used for tracing purposes.
func WrapWithTrace ¶
func WrapWithTrace(c NamedCollector) NamedCollector
WrapWithTrace wraps a NamedCollector with tracing and precomputes metric descriptor names.
type SystemCollector ¶
type SystemCollector struct {
// contains filtered or unexported fields
}
SystemCollector implements NamedCollector and gathers system resource usage like CPU, memory, and disk.
func NewSystemCollector ¶
func NewSystemCollector(ctx context.Context, cfg *config.Config) *SystemCollector
func (*SystemCollector) Collect ¶
func (c *SystemCollector) Collect(ch chan<- prometheus.Metric)
func (*SystemCollector) Describe ¶
func (c *SystemCollector) Describe(ch chan<- *prometheus.Desc)
func (*SystemCollector) MetricsName ¶
func (c *SystemCollector) MetricsName() string
func (*SystemCollector) Shutdown ¶
func (c *SystemCollector) Shutdown() error
