RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: rt-tests-2.4-5.el8
Doc Type: Enhancement
Doc Text:
.The `-W` and `--bucket-width` options have been added to the `oslat` program to measure latency With this enhancement, you can specify a latency range for a single bucket at nanosecond accuracy. Widths that are not multiples of 1000 nanoseconds indicate nanosecond precision. By using the new options, `-W` or `--bucket-width`, you can modify the latency interval between buckets to measure latency within sub-microseconds delay time. For example to set a latency bucket width of 100 nanoseconds for 32 buckets over a duration of 10 seconds to run on CPU range of 1-4 and omit zero bucket size, run the following command: ---- # oslat -b 32 -D 10s -W 100 -z -c 1-4 ---- Note that before using the option, you must determine what level of precision is significant in relation to the error measurement.
