+## Recommendations
+
+The sections below offer recommendations for your production environment. Some
+of them may not apply to your particular use case.
+
+### Health checks
+
+If your code doesn't access the Redis server continuously then it
+might be useful to make a "health check" periodically (perhaps once
+every few seconds). You can do this using a simple
+[`PING`]({{< relref "/commands/ping" >}}) command:
+
+```go
+err := rdb.Ping(ctx).Err()
+
+if err != nil {
+  // Report failed health check.
+}
+```
+
+Health checks help to detect problems as soon as possible without
+waiting for a user to report them.
+
+### Error handling
+
+The `Result()` method of a command returns both the command result
+and an error value. Although you are mainly interested in the result,
+you should also always check that the error value is `nil` before
+proceeding. Errors can be returned for failed connections, network
+problems, and invalid command parameters, among other things.
+
+### Monitor performance and errors
+
+`go-redis` supports [OpenTelemetry](https://opentelemetry.io/). This lets
+you trace command execution and monitor your server's performance.
+You can use this information to detect problems before they are reported
+by users. See [Observability]({{< relref "/develop/clients/go#observability" >}})
+for more information.
