Accelerate your journey to AIOps

• Detect: monitor hybrid infrastructure and

applications and detect issues and anomalies.

• Decide: analyze issues and anomalies to

isolate problems and identify root causes.

• Act: rapidly respond to reduce impact on the

customers with improved resiliency.

AI-powered automation drives operational resiliency and speed

Detect bottlenecks in code,

server resources or with

external dependencies

Accelerates hybrid incident

identification with real-time

operational analytics

Identify anomalous

correlations between

z/OS subsystems

Performance analysis,

capacity forecasting

and modelling

Value: “Enabling domain

experts to diagnose

application bottlenecks

quickly”

Value: “Faster isolation

of problems in hybrid

applications”

Value: “Rapid decrease

in time to identify incident

root cause”

Value: “Standardized

forecasting improved usage

and capacity planning reports”

Analyzing Workloads Today

The IBM Z workload is a black box…

Page 6: IBM z/OS Workload Interaction Correlator IBM z/OS Workload

Challenges Diagnosing Workload Performance Issues

Data is Costly

Data collection requires

significant CPU and

storage to collect and

analyze data

Data is Siloed

Single-component

data generation only

gives one puzzle

piece at a time

resulting in manual

data correlation

Data is Noisy

Significant data generation is often too detailed

resulting in data that is inconsequential to the

reported problemData is the biggest challenge in

analyzing the workloads running on

IBM Z….

Page 7: IBM z/OS Workload Interaction Correlator IBM z/OS Workload

Resource Management Facility Data (RMF) While RMF data is

extremely valuable, it

alone is not sufficient for

identifying root cause of

operational issues in

real time.

Infrequent sampling at

an average of 15

minute intervals

provides only an

overview, missing

transient issues in

workloads.

Historical reporting of z/OS workload requirements

and hardware resource utilization - value is for long

term system performance and capacity planning.

What about RMF Data?

IMS.

with exceptional job

detail per cube.

Dynamically recognize

anomalies in a single

time interval. Anomalous

activities are temporally

correlated and

contextually prioritized

to present only the most

impactful issues.

Cause and victim

relationships can be

visualized across

disparate activities –

reducing root cause

identification time.

Directly comparing the

activities across two

intervals enables the

ability to identify

differences, providing

validation that

workload / software

changes have the

desired effect.

Runs as an application in the IBM Z

Distribution for Zowe™.

IBM Internal SuccessWorkload Interaction Navigator

‒ Customer was experiencing a market open response

time increase.

The Navigator discovered lock contention in WLM

Managed Db2 Stored Procedure address space.

‒ Customer was experiencing an increase in transaction

response times.

The Navigator found a transient zIIP utilization spike that

caused significant zIIP delays as a result of improperly

allocated zIIP configurations.

‒ A 5x increase in CICS response times occurred every 90

seconds.

The Navigator detected that Db2 stopped processing

transaction due to the Db2 log dataset was filling up.

a method to validate

Enable subject matter experts to quickly

determine the cause and victim relationship

across the IBM Z software stack by gaining

visibility into the interdependencies and

interactions across workloads.
