![]() At the end of this guide you’ll have dashboards that you can use to visualize your Node.js metrics, and a set of preconfigured alerts. Finally, you’ll set up a preconfigured and curated set of Grafana dashboards, and alerting rules. You’ll then configure Prometheus to scrape Node.js metrics and optionally ship them to Grafana Cloud. In this guide you’ll learn how to set up and configure prom-client for Node.js to collect Node.js metrics like event loop lag and active handles and expose them as Prometheus-style metrics. To learn how to collect Node.js metrics using the Node.js Integration, please see Node.js Integration from the Grafana Cloud docs. If you’re using Grafana Cloud, you can skip all of the steps in this guide by installing the Node.js Integration, which is designed to help you get up and running in a few commands and clicks. To learn how to do this, please see Reducing Prometheus metrics usage with relabeling from the Grafana Cloud docs. To learn more about configuring prom-client for Node.js and toggling its collectors, please see the prom-client for Node.js GitHub repository.īeyond toggling prom-client for Node.js’s settings, you can reduce metrics usage by dropping time series you don’t need to store in Prometheus or Grafana Cloud. Note that depending on its configuration, prom-client for Node.js may collect and publish far more metrics than this default set. To see a list of metrics shipped by default with this exporter, please download a sample metrics scrape here. This exporter publishes roughly 78 Prometheus time series by default. Set up Prometheus alerting rules to alert on your metrics data. ![]() Imported Grafana dashboards to visualize your metrics data. Set up a preconfigured and curated set of recording rules to cache frequent Prometheus queries. prom-client for Node.js will expose these as Prometheus-style metrics.Ĭonfigured Prometheus to scrape prom-client for Node.js metrics and optionally ship them to Grafana Cloud. ![]() Set up and configured prom-client for Node.js to collect Node.js app metrics like event loop lag, active handles, and GC metrics. After running through the steps in this quickstart, you will have: The following quickstart provides setup instructions and preconfigured dashboards, alerting rules, and recording rules for the prom-client for Node.js Prometheus metrics exporter. ![]()
