Code before:

            throw new Error("No RabbitMQ nodes configured");
        }

        const errors = [];

        for (let i = 0; i < baseUrls.length; i++) {
            const baseUrl = baseUrls[i];
            const nodeIndex = i + 1;
            const totalNodes = baseUrls.length;

            try {
                await this.checkSingleNode(monitor, heartbeat, baseUrl, nodeIndex, totalNodes);
                // If checkSingleNode succeeds, heartbeat is set to UP and we can return
                return;

                const errorMsg = `Node ${nodeIndex}: ${error.message}`;
                log.warn("monitor", `[${monitor.name}] ${errorMsg}`);

Review comment (suggestion):
Please log with `this.name` instead of the prefixing the original impl
This also goes for all other logs in this file 😉 

```suggestion
                log.warn(this.name, errorMsg);
```
