New Relic Agent is a powerful tool designed to monitor and manage application performance. It provides insights into various aspects of your application, including transaction times, error rates, and network metrics. By capturing and analyzing this data, New Relic helps developers optimize their applications for better performance and reliability.
One common issue users encounter is the agent not capturing network metrics. This can manifest as missing data in your New Relic dashboard, particularly in sections related to network performance. Without these metrics, it becomes challenging to diagnose network-related performance issues.
The error code NR-1048 indicates that the New Relic Agent is not capturing network metrics. This can occur for several reasons, including misconfigurations or unsupported network interfaces. Understanding the root cause is crucial for resolving this issue effectively.
To address the NR-1048 issue, follow these steps:
Ensure that network monitoring is enabled in your New Relic Agent configuration file. Locate the configuration file, typically named newrelic.yml, and check for the following settings:
network_monitoring:
enabled: true
If the setting is not enabled, update the file and restart the agent.
Verify that the network interface you are using is supported by New Relic. Refer to the official documentation for a list of supported interfaces. If your interface is unsupported, consider using an alternative interface or contacting New Relic support for assistance.
Ensure that your firewall or security settings are not blocking the agent's ability to send network data. You may need to whitelist New Relic's IP addresses or adjust your security policies. For more information, visit the network configuration guide.
By following these steps, you should be able to resolve the NR-1048 issue and ensure that your New Relic Agent captures network metrics effectively. Regularly reviewing your configuration and staying updated with New Relic's documentation can help prevent similar issues in the future.
