Performance Diagnostics Analysis Period:
Notes:
- Total CPU is the amount of time in milliseconds the process was running on the CPU.
- All dates and times are shown in UTC.
- Some usage spikes may be due to diagnostic tools run by the HPC scenario.
- Performance counter data was collected and is available under the output folder.
