New Relic Agent Agent Not Capturing Cache Usage

Cache usage is not being captured by the agent.

Understanding New Relic Agent

New Relic Agent is a powerful tool designed to monitor applications' performance and health. It provides insights into various metrics, including response times, error rates, and system usage, helping developers optimize their applications effectively. By integrating with different environments, New Relic Agent offers a comprehensive view of your application's performance.

Identifying the Symptom

One common issue that developers may encounter is the agent not capturing cache usage. This can lead to incomplete performance data, making it difficult to diagnose cache-related bottlenecks. The symptom is typically observed when cache metrics are missing from the New Relic dashboard.

Exploring the Issue: NR-1045

The error code NR-1045 indicates that the New Relic Agent is not capturing cache usage. This issue often arises when cache monitoring is not enabled or the cache system in use is not supported by the agent. Understanding the root cause is crucial for resolving this issue effectively.

Common Causes

  • Cache monitoring is disabled in the New Relic configuration.
  • The cache system is not supported by the current version of the New Relic Agent.

Steps to Fix the Issue

To resolve the NR-1045 issue, follow these steps:

Step 1: Verify Cache Monitoring Configuration

Ensure that cache monitoring is enabled in your New Relic configuration file. Locate your newrelic.yml or equivalent configuration file and check for the cache monitoring settings. Ensure that the relevant sections are uncommented and properly configured.

transaction_tracer:
cache: true

Step 2: Confirm Cache System Compatibility

Check if your cache system is supported by the New Relic Agent. Visit the New Relic Agents Documentation to verify compatibility. If your cache system is not supported, consider upgrading to a compatible version or using a supported cache system.

Step 3: Update New Relic Agent

If the issue persists, ensure that you are using the latest version of the New Relic Agent. Updating the agent can resolve compatibility issues and introduce new features. Follow the instructions in the New Relic Agent Installation Guide to update your agent.

Conclusion

By following these steps, you can resolve the NR-1045 issue and ensure that your cache usage is accurately captured by the New Relic Agent. Regularly updating your agent and verifying configuration settings can prevent similar issues in the future. For further assistance, refer to the New Relic Support page.
