Still using Jaeger/Sentry? Uptrace is an open source distributed tracing tool that uses OpenTelemetry to monitor performance, errors, and logs.
database/sql OpenTelemetry Instrumentation
Installation
To install database/sql OpenTelemetry instrumentation:
go get github.com/uptrace/opentelemetry-go-extra/otelsql
Usage
To instrument database/sql, you need to connect to a database using the API provided by otelsql:
| sql | otelsql |
|---|---|
sql.Open(driverName, dsn) | otelsql.Open(driverName, dsn) |
sql.OpenDB(connector) | otelsql.OpenDB(connector) |
import (
"github.com/uptrace/opentelemetry-go-extra/otelsql"
semconv "go.opentelemetry.io/otel/semconv/v1.4.0"
)
db, err := otelsql.Open("sqlite", "file::memory:?cache=shared",
otelsql.WithAttributes(semconv.DBSystemSqlite),
otelsql.WithDBName("mydb"))
if err != nil {
panic(err)
}
// db is *sql.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)
}
What's next?
Next, instrument more operations, for example, database queries, errors, and logs. You can also learn about OpenTelemetry Go Tracing API to create your own instrumentations.
