otelsqlx

sqlx instrumentation for OpenTelemetry Go

otelsqlx instrumentation records sqlx queries (including Tx and Stmt queries) and reports DBStats metrics.

go get github.com/uptrace/opentelemetry-go-extra/otelsqlx

Usage

To instrument sqlx, you need to connect to a database using the API provided by this package:

import (
    "github.com/uptrace/opentelemetry-go-extra/otelsqlx"
    semconv "go.opentelemetry.io/otel/semconv/v1.10.0"
    _ "modernc.org/sqlite"
)

db, err := otelsqlx.Open("sqlite", "file::memory:?cache=shared",
	otelsql.WithAttributes(semconv.DBSystemSqlite))
if err != nil {
	panic(err)
}

// db is *sqlx.DB

And then use context-aware API to propagate the active span via context:

var num int
if err := db.QueryRowContext(ctx, "SELECT 42").Scan(&num); err != nil {
	panic(err)
}

See example for details.

Options

otelsqlx accepts all the options from otelsql package, for example:

import (
    "github.com/uptrace/opentelemetry-go-extra/otelsqlx"
    semconv "go.opentelemetry.io/otel/semconv/v1.10.0"
    _ "modernc.org/sqlite"
)

db, err := otelsqlx.Open("sqlite", "file::memory:?cache=shared",
	otelsql.WithAttributes(semconv.DBSystemSqlite),
	otelsql.WithDBName("mydb"))
