New Relic Agent Agent Not Capturing Disk Metrics

What is New Relic Agent Agent Not Capturing Disk Metrics

Understanding New Relic Agent

New Relic Agent is a powerful tool designed to monitor and manage the performance of your applications and infrastructure. It provides real-time insights into various metrics, helping developers and IT professionals optimize their systems. One of its key functionalities is capturing disk metrics, which are crucial for understanding disk usage and performance.

Identifying the Symptom

The issue at hand is that the New Relic Agent is not capturing disk metrics. This can manifest as missing data in your New Relic dashboard, specifically in the disk performance sections. Without these metrics, it becomes challenging to diagnose disk-related performance issues.

Common Observations

Absence of disk usage data in the New Relic dashboard. Alerts related to missing disk metrics. Inability to track disk performance over time.

Exploring the Issue: NR-1049

The error code NR-1049 indicates that the New Relic Agent is not capturing disk metrics. This issue can arise due to several reasons, including misconfigurations or unsupported disk systems. Understanding the root cause is essential for resolving this problem effectively.

Possible Causes

Disk monitoring is not enabled in the agent configuration. The disk system in use is not supported by the New Relic Agent. Network issues preventing data transmission to New Relic servers.

Steps to Resolve the Issue

To fix the NR-1049 issue, follow these detailed steps:

Step 1: Verify Disk Monitoring Configuration

Ensure that disk monitoring is enabled in your New Relic Agent configuration file. Locate the configuration file, typically named newrelic.yml, and check for the following settings:

disk: enabled: true

If the enabled parameter is set to false, change it to true and restart the agent.

Step 2: Check Disk System Compatibility

Verify that your disk system is supported by the New Relic Agent. Refer to the New Relic compatibility documentation for a list of supported systems. If your system is not listed, consider upgrading or changing your disk system.

Step 3: Restart the New Relic Agent

After making configuration changes, restart the New Relic Agent to apply the updates. Use the following command:

sudo systemctl restart newrelic-infra

Ensure that the agent restarts without errors by checking the status:

sudo systemctl status newrelic-infra

Step 4: Monitor for Improvements

Once the agent is restarted, monitor your New Relic dashboard for disk metrics. It may take a few minutes for the data to appear. If the issue persists, consult the New Relic Support for further assistance.

Conclusion

By following these steps, you should be able to resolve the NR-1049 issue and ensure that your New Relic Agent captures disk metrics effectively. Regularly updating your agent and verifying configurations can prevent such issues in the future.
