Ops Manager 3.4, released at the beginning of December, contains both new features and changes from the previous major release, 2.0. This blog post will focus on the new Ops Manager 3.4 UI. It will cover new features and highlight changes from the previous UI.
Ops Manager 3.4 has a redesigned deployment page. Items that previously appeared in the inner left-hand navigation bar now appear as tabs. Joining the existing tab for Processes are tabs for Servers and Agents. Security settings also now appear under a separate Security tab. These include USERS, ROLES and AUTHORIZATION & TSL/SSL SETTINGS. The TOPOLOGY and LIST views are now accessed via buttons. Additional functions are accessible under More: Host Mappings, Version Manager, and Logs.
Ops Manager 2.0 featured dedicated icons on the top of page showing the health of the agents.
In Ops Manager 3.4, agent health is reported via alerts. These alerts function identically to all other alerts and appear in the Alerts tab. Agent alerts are active by default.
In Ops Manager 2.0, the alert types (OPEN ALERTS, CLOSED ALERTS, ALL ACTIVITY) are selected using buttons. The alert settings page is accessed via the ellipsis button in the upper right-hand corner of the page. The settings page contains the ADD button, via which new alerts are created.
In Ops Manager 3.4, the alert types have become tabs. In addition to the 3 alert types, alert settings have been moved to a fourth tab, Alert Settings. The ADD button is now on the main alerts page, right above the tabs.
In Ops Manager 2.0, metric chart zoom and granularity are set via buttons. "Last Ping" information is accessed via the ellipsis button.
In Ops Manager 3.4, zoom and granularity were changed to drop-down menus, and an additional 10-second granularity setting was added for improved resolution. The granularity drop-down also has a new "auto" setting which chooses the optimum granularity based on the display period. "Last Ping" information is now listed under More. For HW metrics, use of munin-node is no longer required. HW metrics are automatically gathered for automated deployments.
Documentation and Support
For Ops Manager 2.0, documentation and support were accessed via icons in the top-right corner of the page.
In Ops Manager 3.4, those are accessed via buttons at the bottom of the left-hand navigation bar.
For Ops Manager 3.4, existing functionality on the Admin page remains identical to version 2.0. This page is also the location for accessing two new features: S3 blockstore configuration for backups (under the existing Backup button) and server pool administration (under the new Server Pool button). For more details on these features, see the Ops Manager documentation.

Australian Start-Up Ynomia Is Building an IoT Platform to Transform the Construction Industry and its Hostile Environments
The trillion dollar construction industry has not yet experienced the same revolution in technology you might have expected. Low levels of R&D and difficult working environments have led to a lack of innovation and fundamental improvements have been slow. But one Australian start-up is changing that by building an Internet of Things (IoT) platform to harness construction and jobsite data in real time. “Productivity in construction is down there with hunting and fishing as one of the least productive industries per capita in the entire world. It's a space that's ripe for people to come in and really help,” explains Rob Postill , CTO at Ynomia. Ynomia has already been closely involved with many prestigious construction projects, including the residential N06 development in London’s famous 2012 Olympic Village. It was also integral to the construction of the Victoria University Tower in Australia. Link to Podcast Episode Here “These projects involve massive outflow of money: think about glass facades on modern buildings, which can represent 20-30 percent of the overall project cost. They are largely produced in China and can take 12 weeks to get here,” says Postill. “Meanwhile, the plasterer, the plumber, the electrician are all waiting for those glass facades to be put on so it is safe for them to work. If you get it wrong, you can go in the deep red very quickly.” To tackle these longstanding challenges, Ynomia aims to address the lack of connectivity, transparency and data management on construction sites, which has traditionally resulted in the inefficient use of critical personnel, equipment and materials; compressed timelines; and unpredictable cash flows. To optimize productivity, Ynomia offers a simple end-to-end technology solution that creates a Connected Jobsite. Helping teams manage materials, tools, and people across the worksite in real time. IOT in a Hostile Environment The deployment of technology in construction is often fraught with risk. As a result, construction sites are still largely run on paper, such as blueprints, diagrams and models as well as the more traditional invoices and filing. At the same time, there is a constant need to track progress and monitor massive volumes of information across the entire supply chain. Engineers, builders, electricians, plumbers, and all the other associated professionals need to know what they need to do, where they need to be, and when they need to start. “The environment is hostile to technology like GPS, computers, and mobile phone reception because you have a lot of Faraday cages and lots of water and dust,” explains Postill. “You can't have somebody wandering around a construction site with a laptop; it'll get trashed pretty quickly." Enter MongoDB Atlas “On a site, you might be talking about materials, then if you add to that plant & equipment, or bins, or tools etc, you're rapidly getting into thousands and thousands of tags, talking all the time, every day,” said Postill. That means thousands of tags now send millions of readings on Ynomia building sites around the world. All these IoT data packets must be stored efficiently and accurately so Ynomia can reassemble the history of what has happened and track tagged inventory, personnel, and vehicles around the site. Many of the tag events are also safety critical so accuracy is a vital component and packets can't be missed. To address these needs Ynomia was looking for a database that was scalable, flexible, resilient and could easily handle a wide variety of fast-changing sensor data captured from multiple devices. The final component Postill was looking for in a database layer was freedom: a database that didn't lock them into a single cloud platform as they were still in the early stages of assessing cloud partners. The Commonwealth Scientific and Industrial Research Organisation , which Postill had worked with in the past, suggested MongoDB , a general purpose, document-based database built for modern applications. “The most important factor was that the database is event-driven, which I knew would be difficult in the traditional relational model. We deal with millions of tag readings a day, which is a massive wall of data,” said Postill. A Cloud Database Ynomia is using MongoDB Atlas , the global cloud database service, now hosted on Microsoft Azure. Atlas offers best-in-class automation and proven practices that combine availability, scalability, and compliance with the most demanding data security and privacy standards. “When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go." Postill says this combination of flexibility and management tooling also allows his developers to focus on business value not undifferentiated code. One example Postill gave was cluster administration: "Cluster administration for a start-up like us is wasted work," he said. "We’re not solving the customer's problem. We're not moving anything on. We’re focusing on the wrong thing. For us to be able to just make that problem go away is huge. Why wouldn’t you?" Atlas also gives Ynomia the option to spin out new clusters seamlessly anywhere in the world. This allows customers to keep data local to their construction site, improving latency and helping solve for regional data regulations. Real Time Analytics The company has also deployed MongoDB Charts, which takes this live data and automatically provides a real time view. Charts is the fastest and easiest way to visualize event data directly from MongoDB in order to act instantly and decisively based on the real-time insights generated by event-driven architecture. It allows Ynomia to share dashboards so all the right people can see what they need to and can collaborate accordingly. “Charts enables us to quickly visualize information without having to build more expensive tools, both internally and externally, to examine our data,” comments Postill. “As a startup, we go through this journey of: what are we doing and how are we doing it? There's a lot of stuff we are finding out along the way on how we slice and re-slice our data using Charts.” A Platform for Future Growth Ynomia is targeting a huge market and is set for ambitious growth in the coming years. How the platform, and its underlying architecture, can continue to scale and evolve will be crucial to enabling that business growth. “We do anything we can to keep things simple,” concluded Postill. “We pick technology partners that save us from spending time we shouldn't spend so we can solve real problems. We pick technologies that roll with the punches and that's MongoDB.” When we started we didn't know enough about the problem and we didn't want to be constrained," explained Postill. "MongoDB Atlas gives us a cloud environment that moves with us. It allows us to understand what is happening and make changes to the architecture as we go. Rob Postill, CTO, Ynomia
