Skip to main contentTo view the resource usage for a workflow, navigate to the Usage Report tab for a workflow execution.
The following is a usage report for a nf-core/methylseq execution.
The report collects 5 key metrics for each workflow task:
- CPU: Each data point represents the number of cores used by the task over a time period.
This time period is determined by the operating system and defaults to 100 milliseconds.
For example, a value of 2.0 cores means that the task used 2 cores in the past 100 milliseconds.
Note: The number of cores used may be temporarily higher than the number of cores allocated.
This can happen if the task is scheduled on a machine with more cores than what was requested by the task.
This is expected behavior.
- Memory: Number of bytes of memory allocated by the task.
- Disk: Number of bytes of local disk space (EBS) used by the task.
- Network Rx: Bytes received over the network. Only displayed on task completion.
- Network Tx: Bytes transmitted over the network. Only displayed on task completion.
For running tasks, the usage report shows the latest usage for each metric.
For completed tasks, it shows the average usage.
To further investigate usage for a particular task, select the blue icon next to the metric to view
a graph of usage over time.
You can easily navigate to your highest usage tasks by selecting a header to sort the table by.
