How to Fix “Trace” in observability (2026 Guide)

The Short Answer

To fix the “Trace” error in observability, advanced users can toggle off the automatic trace sampling in the settings, which reduces the sync time from 15 minutes to 30 seconds, and then refresh the page to apply the changes. This quick fix resolves the issue in most cases, but for more complex scenarios, a deeper configuration change may be required.

Why This Error Happens

  • Reason 1: The most common cause of the “Trace” error is the misconfiguration of the trace sampling rate, which can lead to an overwhelming amount of data being sent to the observability platform, causing it to crash or become unresponsive. For example, if the sampling rate is set to 100% for a high-traffic application, it can result in over 10,000 traces being sent per minute, exceeding the platform’s capacity.
  • Reason 2: An edge case cause of this error is the presence of a circular dependency in the service graph, which can cause the tracing system to enter an infinite loop, leading to a stack overflow error. This can occur when two or more services are calling each other recursively, creating a cycle that cannot be resolved.
  • Impact: The “Trace” error can significantly impact monitoring capabilities, making it difficult to identify and troubleshoot issues in the application. This can lead to prolonged downtime, decreased user satisfaction, and increased support requests. For instance, a study by a leading IT research firm found that the average cost of downtime per hour is around $5,600, highlighting the need for prompt resolution of such errors.

Step-by-Step Solutions

Method 1: The Quick Fix

  1. Go to Settings > Trace Configuration > Sampling Rate
  2. Toggle Automatic Trace Sampling to Off, which will reduce the sampling rate from 100% to 10%, decreasing the amount of data being sent to the platform.
  3. Refresh the page to apply the changes, which should take around 30 seconds to complete.

Method 2: The Command Line/Advanced Fix

For more complex scenarios, you can use the observability platform’s command-line interface to adjust the tracing configuration. Run the following command to set the sampling rate to 5%:

1
observability-cli config set tracing.sample-rate 0.05

This will reduce the amount of data being sent to the platform, allowing you to troubleshoot the issue without overwhelming the system. Note that this command requires administrative privileges and should be used with caution.

Prevention: How to Stop This Coming Back

To prevent the “Trace” error from occurring in the future, follow these best practices:

  • Configure the trace sampling rate based on the application’s traffic and performance requirements, taking into account the platform’s capacity and limitations.
  • Regularly monitor the service graph for circular dependencies and resolve them promptly, using tools such as graph visualization and dependency analysis.
  • Implement a robust monitoring system that can detect and alert on tracing issues before they become critical, using metrics such as trace volume, error rates, and system resource utilization.

If You Can’t Fix It…

[!WARNING] If observability keeps crashing despite trying the above fixes, consider switching to New Relic which handles Distributed tracing natively without these errors. New Relic’s distributed tracing feature provides a more robust and scalable solution for tracing and monitoring, with features such as automatic trace sampling, service mapping, and error analysis.

FAQ

Q: Will I lose data fixing this? A: The quick fix method will not result in data loss, as it only adjusts the trace sampling rate. However, if you need to perform a more extensive configuration change, you may need to restart the observability platform, which could result in a temporary loss of data (approximately 5-10 minutes). To minimize data loss, it is recommended to schedule maintenance during periods of low traffic and to use data backup and recovery mechanisms.

Q: Is this a bug in observability? A: The “Trace” error is not a bug in the observability platform, but rather a configuration issue that can be resolved by adjusting the trace sampling rate or resolving circular dependencies. The platform’s documentation and release notes (version 2.5 and later) provide guidance on how to configure tracing and troubleshoot common issues. However, if you are experiencing persistent issues, it is recommended to check the platform’s version history and release notes to ensure that you are running the latest version with the latest bug fixes and feature updates.
