4. Are key resources being overused?
On this page
The next step in troubleshooting your cluster is looking at key resources to see if they are being overused.
-
For a quick sanity check, navigate to the Studio Dashboard to look at resource usage against their respective totals available by hovering over each.
-
Check the Studio Hosts and/or Nodes pages to look at CPU and memory usage.
-
Sort on CPU Usage, Memory Usage, and Disk Usage.
Are there resources being overused? -
If you see one or more resources approaching their limit (e.
g. , memory, disk, or CPU limits), consider the following: -
Have you added a new workload to your cluster that is using more resources?
-
Have you loaded more data (on disk, or in memory)?
-
Have you increased concurrency?
-
Does your workload require more nodes to meet the scale?
-
Is there an expensive workload or query that is causing a spike and could be optimized?
