It’s been a real pleasure to attend to 2016 CMG Italia Annual Conference, organized as a two-day event, held in Rome and Milan on 24th – 25th of May.
The Computer Measurement Group is a not-for-profit, worldwide organization of IT professionals committed to sharing information and best practices focused on ensuring the efficiency and scalability of IT service delivery to the enterprise through measurement, quantitative analysis and forecasting.
Near real-time performance & capacity information is getting more and more consideration within enterprise IT departments. Continuos delivery of new applications’ features is introducing a new challenge for IT managers: new releases may cause excessive resources’ usage or degraded performance, without having any benefits for the business. Considering the complexity of today’s IT environments, such anomalies can easily go unnoticed, until you have to pay your bills.
Roberto Gioi, Head of Capacity Management at Monte dei Paschi di Siena, presented an interesting approach to release management control. His team developed a solution that integrates with the release management process and helps detecting resource usage anomalies of newly released applications; once a capacity incident is identified, the team is able to send a notification to the application’s owner and possibly add an optimization suggestion.
David Furnari, Manager at Moviri, addressed the problem with Mainframe resources: reducing their utilization could lead to large savings. David presented a near real-time monitoring dashboard that uses workload characterization to show how a business service is consuming MIPS and whether a load increase is related to business volumes increase or preformance degradation. Mainframe’s resource monitoring is still perceived as a topic that pertains to technicians only: instead, the information you collect is valuable for managers too, if you can connect technical metrics with business service labels.
Stefano Doni, Performance & Capacity evangelist at Moviri, brought on stage for the first time in Italy his paper on Java application memory that granted him the Best Paper Award at the 2015 CMG International. This study, through actionable methodologies, enables you to highlight the hidden bottlenecks of many Java applications, detect poor memory usage patterns and anticipate memory leaks.
Other interesting sessions were held by EPV Technologies (event organizer) about new technologies, like Simultaneous Multi-Threading, which represents a revolution in the Mainframe world and adds complexity for special engines (zIIP) capacity planning that are not related with the MIPS bill.
