Monitor CPU and memory usage alongside API metrics

We’ve added a new Resources dashboard to Apitally, providing visibility into your application’s CPU and memory usage alongside other API metrics. This allows you to monitor application health and correlate resource consumption with API traffic in a single view.

Resources dashboard

The new dashboard tracks CPU and memory usage over time, aggregated across all running instances per environment.

• CPU utilization: The percentage of CPU time used by your application processes. As this is measured per-process, values can exceed 100% for multi-threaded applications utilizing multiple cores.
• Memory usage: The resident set size (RSS) of the processes, representing the actual physical memory being used.

Each chart displays the average value as a line, with a shaded area indicating the range between the minimum and maximum values across your instances.

Traffic overlay

You can toggle Overlay traffic to show requests per minute (RPM) directly on the resource charts.

This helps visualize the relationship between API traffic volume and resource consumption, making it easier to distinguish between load-related spikes and potential performance regressions or memory leaks.

Alerts for resource metrics

We’ve also updated custom alerts to support the new resource metrics. You can now configure alerts based on:

• CPU utilization (average & maximum)
• Memory usage (average & maximum)

For example, you can receive notifications in Slack if the average CPU utilization of your application’s processes exceeds 80%, or if a single instance’s memory usage goes above a specific threshold (e.g., 500 MB).

Getting started

Resource metrics are collected automatically by the Apitally SDK. Simply update your SDK to the latest version to get started. No additional configuration or code changes are required.

These new features are available to all users on all plans.
