Solution

Follow these steps to identify and troubleshoot the cause.

  1. Use New Relic APM’s Transaction page to identify transactions with performance issues:

  2. If you are still struggling to identify the source, use New Relic APM’s Infrastructure page to identify resource heavy services. For steps, refer to New Relic Infrastructure monitoring Hosts page > Processes tab.

  3. If you identify the source, SSH into the environment to investigate further. For steps, refer to Cloud for Adobe Commerce > SSH into your environment in our developer documentation.

  4. If you are still struggling to identify the source:

    • Review recent trends to identify issues with recent code deployments or configuration changes (for example, new customer groups and large changes to the catalog). It is recommended that you review the past seven days of activity for any correlations in code deployments or changes.
    • Consider checking for and disabling flat catalogs. For steps, refer to Slow performance, slow and long running crons in our support knowledge base.
    • If you suspect that you are experiencing a DDoS attack, try blocking bot traffic. For steps, refer to How to block malicious traffic for Adobe Commerce on Fastly level in our support knowledge base.
  5. If the problem seems temporary, perform mitigation steps such as an upsize or place the site into maintenance mode. For steps, refer to How to request temp resize in our support knowledge base, and Installation Guide > Enable or disable maintenance mode in our developer documentation. If the upsize returns the site to normal operations, consider requesting a permanent upsize (contact your Adobe Account Team) or try to reproduce the problem in your Dedicated Staging by running a load test and optimize queries, or code that reduces pressure on services. For steps, refer to Cloud for Adobe Commerce > Test Deployment > Load and stress testing in our developer documentation.
