How can I visualize Node.js metrics in Grafana?
You can visualize Node.js metrics in Grafana by using Prometheus as a data source. First, ensure you have Prometheus set up to scrape metrics from your Node.js application.
What metrics should I collect from my Node.js app?
You should consider collecting metrics like request latency, error rates, memory usage, and CPU load. These will give you a good overview of your app's performance.
How do I set up Prometheus to scrape my Node.js app?
You need to use the 'prom-client' library in your Node.js app to expose metrics. Then, configure Prometheus to scrape the endpoint where these metrics are exposed.
Can you guide me on creating a Grafana dashboard for these metrics?
Sure! In Grafana, create a new dashboard, add a panel, and select Prometheus as the data source. Then, you can query the metrics you want to visualize.
