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.

1. Feature Overview:
Feature Id:	[201591]
a. Name of Feature:	FCP - Performance Data collection & analysis (userspace)
b. Feature Description
The item comprises: a) facilities which provide performance relevant data (see below) at any time b)
facilities which collect the data provided by a), then associate it with a time stamp and and store
it for future processing - these facilities are configurable in regard of the type and amount of
data collected for the purpose of reducing the amount of temporarily stored data. - when data is
taken as samples, the sampling interval is configurable - collected data can be filtered by e.g
masks for valid stack components (see below) before data is stored for further processing c)
facilities which present the data stored by b) in a human readable way. d) Data presented shall
contain enough information to make FCP performance data comparable with current capabilities of
FICON data collections. Data collected comprises: a) Performance relevant data about stack
components as Linux devices, SCSI LUNs and HBA and storage controller information b) Per stack
component: current values of relevant measurements as throughput, utilization and other applicable
measurements c) Statistical aggregations (min, max average, histogram) of data associated with I/O
requests as size, latency per component and in total.

Additional Comments:	This feature is the userspace part to feature 201590 FCP - Performance Data
collection & analysis (kernel), and feature 201729 FCP - Performance Data collection & analysis
(blktrace)
