Get the package from the Github repository:

go get -u github.com/pip-services4/pip-services4-go/pip-services4-observability-go@latest

Example how to use Logging and Performance counters. Here we are going to use CompositeLogger and CompositeCounters components. They will pass through calls to loggers and counters that are set in references.

import (
	"context"

	"github.com/pip-services4/pip-services4-go/pip-services4-components-go/config"
	"github.com/pip-services4/pip-services4-go/pip-services4-components-go/refer"
	"github.com/pip-services4/pip-services4-go/pip-services4-observability-go/count"
	"github.com/pip-services4/pip-services4-go/pip-services4-observability-go/log"
)

type MyComponent struct {
	logger   *log.CompositeLogger
	counters *count.CompositeCounters
}

func (c *MyComponent) Configure(ctx context.Context, config *config.ConfigParams) {
	c.logger.Configure(ctx, config)
}

func (c *MyComponent) SetReferences(ctx context.Context, references refer.IReferences) {
	c.logger.SetReferences(ctx, references)
	c.counters.SetReferences(ctx, references)
}

func (c *MyComponent) MyMethod(ctx context.Context,  param1 any) {
	c.logger.Trace(ctx, "Executed method mycomponent.mymethod")
	c.counters.Increment(ctx, "mycomponent.mymethod.exec_count", 1)
	timing := c.counters.BeginTiming(ctx, "mycomponent.mymethod.exec_time")
	defer timing.EndTiming(ctx)
	// ....

	if err != nil {
		c.logger.Error(ctx, err, "Failed to execute mycomponent.mymethod")
		c.counters.Increment(ctx, "mycomponent.mymethod.error_count", 1)
	}
}
