Performance resource management

Performance resource management

  • OneFS performance resource management provides statistics for the resources used by jobs—both clusterwide and per-node. This information is available through the isi statistics workload CLI command. Available in a top format, this command displays the top jobs and processes, and periodically updates the information.

    For example, the following syntax shows, and indefinitely refreshes, the top five processes on a cluster:

    The resource statistics tracked per job, per job phase, and per node include CPU, reads, writes, and L2 and L3 read hits. Unlike the output from the top command, this information makes it easier to diagnose individual job resource issues and similar issues.
