Datadog Agent is a powerful tool designed to collect metrics, logs, and traces from your infrastructure and applications. It acts as a bridge between your systems and Datadog's cloud-based monitoring platform, enabling real-time visibility into your environment. The agent supports a wide range of integrations, allowing you to monitor various aspects of your infrastructure, including CPU, memory, network, and disk usage.
One common issue users encounter is the Datadog Agent not collecting disk metrics. This symptom is observed when expected disk-related data, such as disk usage or I/O statistics, is missing from the Datadog dashboard. This can hinder your ability to monitor disk performance and identify potential bottlenecks or failures.
The primary reasons for this issue include:
First, verify that disk metrics collection is enabled in the Datadog Agent configuration file. The configuration file is typically located at /etc/datadog-agent/datadog.yaml on Linux systems.
To enable disk metrics collection, follow these steps:
sudo nano /etc/datadog-agent/datadog.yaml
collect_disk: true
Ensure the Datadog Agent has the necessary permissions to access disk data:
ps aux | grep datadog
After making configuration changes, restart the Datadog Agent to apply them:
sudo systemctl restart datadog-agent
For more detailed information on configuring the Datadog Agent, refer to the official Datadog documentation. Additionally, you can explore the Disk Integration Guide for specific disk monitoring configurations.
