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.

2. Feature Details:
Sponsor:	zSeries

Arch Specificity: Purely Arch Specific Code
Delivery Mechanism: Backport
Category:	zSeries
Request Type:	Package - Feature from Upstream
d. Upstream Acceptance:	Accepted
Sponsor Priority	1
f. Severity: High
IBM Confidential:	no
Code Contribution:	IBM code
g. Component Version Target:	s390tools 1.7.x

3. Business Case
This item will make possible to have a better understanding of the SCSI activities and performance
of the customer system, being able afterward to better solve FCP issues regarding customer's SCSI

IBM is signed up to test and provide feedback.
Comment 2 IBM Bug Proxy 2009-01-23 09:17:43 EST
This feature has corresponding feature requests.
All three features are required to implement the requested functionality

201590	FCP - Performance Data collection  (kernel)	   LTC 50339
RHBZ 475334

201729	FCP - Performance data collection (blktrace)  LTC 50351
RHBZ 475548
Comment 3 John Jarvis 2009-01-29 16:17:18 EST
closing as duplicate of BZ 477189 [LTC 5.4 FEAT] Pick up latest version of
s390-tools since we plan to rebase s390utils in RHEL 5.4
