# Metrics

The **Metrics** dashboard provides a visual overview of classic monitoring metrics for your host, such as CPU usage, memory, and network traffic. It also shows the utilization and performance of each disk on the host.

{% hint style="info" %}
The retention period for metrics is 14 days by default. You can adjust this period in the configuration file.
{% endhint %}

{% hint style="success" icon="lightbulb" %}
For more information on how to change the retention periods for Enginsight log entries, see our Knowledge Base: [How can I adjust the retention periods for my Enginsight logs?](https://docs.enginsight.com/docs/knowledge-base/english/logging/how-can-i-adjust-the-retention-periods-for-my-enginsight-logs)
