Using Stack Metrics to monitor platform health

This feature is available to Acquia Cloud, Acquia Cloud Enterprise, and Acquia Cloud Site Factory subscribers.

Using Stack Metrics graphs

The Acquia Cloud Stack Metrics feature provides real-time and historical information about an application’s performance, health, and resource use.

Certain Stack Metrics graphs, such as CPU and Memory, are designed to show the average reported value over a given period to prevent transient spikes in utilization from inaccurately skewing data points. As a result, instances may be utilizing higher CPU/memory than shown on the graphs for short periods of time. While short-lived spikes usually do not impact application performance, prolonged or frequent spikes can, and if sustained, these spikes will appear in your graphs.

Stack Metrics graphs may differ slightly from those provided by Acquia for diagnostic purposes as a result of differning granularity on our internal monitoring services.

To use Stack Metrics, complete the following steps:

  1. Sign in to the Acquia Cloud interface.
  2. Select your application and environment.
  3. In the left menu, click Stack Metrics.

You can also use the list preceding the metrics charts to select a time period to review. Available timeframes span from the last hour to the last 6 months, or set a Custom Range. Clicking a new timeframe in the list refreshes the charts based on your selection.

These metrics reflect server-wide activity unless noted otherwise.

Upsizing your servers

If your application has problems that may be remedied by a server upsize while you troubleshoot the issue, see the following pages for how to resize your servers to meet your application’s needs:
