Issue

You will receive an alert in New Relic if you have signed up to Managed alerts for Adobe Commerce and one or more of the alert thresholds have been surpassed. These alerts were developed by Adobe Commerce to give customers a standard set using insights from Support and Engineering.

Do!:

  • It is recommended that you abort any deployment scheduled until this alert is cleared.
  • Put your site into maintenance mode immediately if your site is or becomes completely unresponsive. For steps, refer to Installation Guide > Enable or disable maintenance mode in our developer documentation. Make sure to add your IP to the exempt IP address list to ensure that you are still able to access your site for troubleshooting. For steps, refer to Maintain the list of exempt IP addresses in our developer documentation.

Don’t!:

  • Launch additional marketing campaigns which may bring additional pageviews to your site.
  • Run indexers or additional crons, which may cause additional stress on CPU or disk.
  • Do any major administrative tasks (i.e., the Admin, data imports/exports).
  • Clear your cache.

Solution

Follow these steps to identify and troubleshoot the cause.

  1. Use New Relic APM’s Infrastructure page to identify top memory-intensive processes. For steps, refer to New Relic Infrastructure monitoring Hosts page > Processes tab. If services like Redis or MySQL are the top source of memory consumption, try the following:

  2. If you are still struggling to identify the source of the problem, use New Relic APM’s Transaction page to identify transactions with performance issues:

    • Sort transactions by ascending Apdex scores. Apdex refers to user satisfaction to the response time of your web applications and services. A low Apdex score can indicate a bottleneck (a transaction with a higher response time). Usually, it is the database, Redis, or PHP. For steps, refer to New Relic View transactions with highest Apdex dissatisfaction.
    • Sort transactions by highest throughput, the slowest average response time, most time-consuming, and other thresholds. For steps, refer to New Relic Find specific performance problems. If you are still struggling to identify the issue, use New Relic APM’s Infrastructure page.

  3. If you cannot identify the cause of increased memory consumption, 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.

  4. If the above methods do not help you find the cause and/or solution within a reasonable time, request an upsize or place the site into maintenance mode if you have not already. 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.

  5. If the upsize returns the site to normal operations, consider requesting a permanent upsize (contact your CSM), 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. Refer to Adobe Commerce on cloud infrastructure > Test Deployment > Load and stress testing in our developer documentation.
