--seconds seconds Time interval in seconds at which to print the perf metrics. (default: 2)
--no-timestamp Omit timestamps from the performance metrics output
--default Show default list of metrics for each category.
--extended Show extended list of metrics for each category.
--all Show full list of all metrics for each selected category.
--filter groups Show only metrics for the specified (comma separated) groups (see option descriptions for the available groups).
--fail-on-error Fail on perf retrieval errors
