How to Power AI Analytics with IBM Z and IBM i

Authors Photo Precisely Editor | May 3, 2023

Real-time AI analytics are playing an increasingly important role in today’s midsize and large enterprises. Whether your focus is operational data analytics, service intelligence, or security information, it’s important to have systems in place to monitor, analyze, and report information. IT data analytics is the foundation stone upon which IT excellence is built.

Splunk is a leading platform for IT analytics. Unfortunately, if your company is running IBM i or IBM Z systems, you need to improve the observability of these systems in Splunk. Although IBM systems serve as a backbone for many core applications in a business, the operational information about performance, security, and technical operations of these systems, remains inaccessible by Splunk.

IBM Z, for example, includes the System Management Facility (SMF), but that information remains inaccessible to Splunk in its native format. When IT teams cannot see how IBM Z platforms are performing, service disruptions can take a longer time to resolve or even cause expensive downtime in discovering the issue.

The good news is that there are viable options for bridging the gap between your IBM systems and IT data analytics (whether you are using Splunk or another tool). Let’s look at some scenarios where this can add value to your IT operations strategy.

Splunk and the Mainframe: 6 Real-World Case Studies for ITOA, ITSI and SIEM

To learn more about Ironstream and explore real world case studies for ITOA, ITSI, and SIEM where new technologies can provide answers to the questions challenging organizations, read our eBook.

IT service intelligence (ITSI)

ITSI is about mapping and monitoring an organization’s IT environment to identify potential problems, prioritize issues, and resolve incidents promptly. In addition, ITSI is used to track Key Performance Indicators (KPIs) in order to ensure that service levels are meeting the expected standards.

A luxury auto dealer network serving the Americas was running CICS and Db2 apps on its IBM Z, which interacted with dealer IT systems across the continent. The system was experiencing significant performance problems, but company IT personnel were entirely unaware of those problems until a dealership complained directly to the company’s CIO. The organization’s existing ITSI systems had no direct visibility to the mainframe’s performance logs. Because its IBM system was, in effect, walled off from its distributed systems, the company’s existing IT analytics system had no awareness of the problem whatsoever.

The auto dealer network rolled out Precisely Ironstream, along with the Ironstream Module for Splunk IT Service Intelligence. That provided immediate visibility to the relevant information from the IBM mainframe, giving the organization’s IT personnel a complete picture of its entire IT landscape for the first time ever. As a result, the company was able to reduce the mean time to resolution (MTTR), speed the flow of information, and increase the satisfaction of the dealers whom it served.

IT operational analytics (ITOA)

While ITSI is focused on identifying, prioritizing, and resolving issues, ITOA is about informing operational decisions about an organization’s IT landscape. Once again, significant challenges may arise when technology leaders within the company have an incomplete picture of that landscape.

A global financial services firm, for example, had identified some high-priority issues on one of its IBM Z. The firm was seeking to better understand its options for maintaining operational efficiency and controlling costs.

One particular job, for instance, was consuming 30% more CPU time than was normal. That issue was typical of the problems the firm was seeing elsewhere in its IT landscape, and it was costing the company time and money. The organization’s mean time to resolution was significantly longer than it should have been, and its existing systems could not alert the team promptly to issues in various business units across the company. Perhaps most importantly, there was no connection between the organization’s IBM Z and its distributed computing systems.

To make better operational decisions, the company knew it needed to have a complete picture of its IT landscape. In the past, the firm was handling that process the hard way, by offloading SMF data from the mainframe on a daily basis, extracting the required records and fields from that, then using SAS to generate reports about mainframe performance.

The team soon realized, however, that this approach was exceedingly inefficient, so they began looking for a better way of doing the job. The firm selected Precisely Ironstream to help the team process and forward SMF data to the Splunk Enterprise analytics platform. This gave the company a real-time view of system performance, without costly and time-consuming manual intervention.

Security information and event management (SIEM)

A large healthcare organization was struggling with SOC2 certification because the SMF logs from its three IBM mainframe systems were inaccessible to Splunk Enterprise. The organization was using IBM’s zSecure products alongside some in-house utilities to manage security-related tasks and data. This organization’s situation was especially challenging because of the sheer volume of SMF data, which had the potential to grow as high as 800 GB per day.

The healthcare organization created an automated process with Ironstream, forwarding selected SMF records to Splunk to track the information needed for SOC2 certification compliance. This provided real-time visibility and enabled the organization to eliminate the manual processes and related costs associated with using zSecure.

In another case, a federal law enforcement agency was grappling with security compliance audits, which required it to collect and analyze log data from a variety of systems across its IT landscape. The agency had selected Splunk Enterprise for log management, but one important piece of the puzzle was missing. The organization’s IBM mainframe housed some extremely sensitive information, including authentication data, enterprise-wide details on password changes, log-in successes and failures, and account lock-outs, but that information was inaccessible to Splunk.

By implementing Precisely Ironstream, this federal agency gained access to a complete picture of security-related events in real time, giving it all the information needed to comply with security audits.

Ironstream provides the critical missing link between IBM mainframes and Splunk Enterprise for IT analytics.  Precisely has been a Splunk Technology Alliance partner since 2014, and with our Ironstream product, we provide the industry’s premier mainframe log data access solution for Splunk customers.
