Measuring Memory Usage

Overview

Measuring memory usage is crucial for optimizing an application’s performance and ensuring it runs efficiently. By implementing effective memory usage measurement practices, you can enhance user experience, and prevent potential issues related to excessive memory consumption.

Prerequisites

To measure app memory usage, your website must be in a secure context.

Configuration

Coralogix allows you to track the memory usage of your application via the measureUserAgentSpecificMemory API.

Automatic

The SDK collects memory usage data every interval and sends it to Coralogix.

Example

CoralogixRum.init({
  // ...
  memoryUsageConfig:{
    enabled:true,
    interval: 300_000 // Defaults to 5 minutes
  }
});

Manual

You can also manually trigger memory usage data collection via CoralogixRum.measureUserAgentSpecificMemory();

Querying memory data

To effectively analyze memory usage, utilize the following attributes in your queries:

  • cx_rum.event_context.type:"memory-usage - Event type for querying all memory usage events.

  • cx_rum.memory_usage_context.breakdown.types - Object types that consume the memory (DOM, shared workers, window, etc.).

  • cx_rum.memory_usage_context.breakdown.bytes - Memory usage for each object type.

  • cx_rum.memory_usage_context.bytes - Total memory consumption across all objects.
