In the Dashboards page, you can see 6 different dashboards which can be further customized or used as is:
Click on each of them to see the detailed monitoring information. Note that some of the dashboards (e.g. Compute Node List, Compute Node Details) will not show any information until a job is launched (since we start with zero compute nodes in our cluster to save costs).
| Dashboard | Description |
|---|---|
| ParallelCluster Stats | This is the main dashboard that shows general monitoring info and metrics for the whole cluster. It includes Slurm metrics and Storage performance metrics. |
| Master Node Details | This dashboard shows detailed metric for the Master node, including CPU, Memory, Network and Storage usage. |
| Compute Node List | This dashboard show the list of the available compute nodes. Each entry is a link to a more detailed page. |
| Compute Node Details | Similar to the master node details this dashboard show the same metric for the compute nodes. |
| Cluster Logs | This dashboard shows the logs of your HPC Cluster. The logs are pushed by AWS ParallelCluster to AWS ClowdWatch Logs and finally reported here. |
| Cluster Costs | This dashboard shows the cost associated to every AWS Service utilized by your Cluster. It includes: EC2, EBS, FSx, S3, EFS. |
For example, here’s what the Master Node Details dashboard looks like:
