# Find usage spikes

The CPU and memory usage panels on the Overview page show spikes across your fleet at a glance and let you jump directly to the affected Cluster.

Use the time range selector to focus on a time period while looking for patterns or spikes in CPU and memory usage in your Clusters. When spikes occur:

1. Zoom in on the graph to narrow the time selection.

2. Hover over and click the peak of the spike to see the percentage of use compared to capacity. In the following example, the spike shows 46.5% of CPU usage compared to capacity.

3. Click the **View** link to view the Cluster. The Cluster detail page shows the time range you set when zooming in on the graph.

   You can continue by sorting the list of Nodes in this Cluster by highest CPU usage to investigate the issue causing the spike.
