In Linux, calculating available memory is not always straightforward. This is because Linux treats memory resources differently than other operating systems. Because of this, many Linux server monitoring tools do not properly calculate the true value of the property correctly, because of what Linux is doing with memory resources behind the scenes. So a Linux admin running a Linux system might see that they have zero (0) Memory resources available, when in fact plenty of memory is available.
Linux, by design, uses RAM memory for disk caching to speed up the system. This means that the Mem % Free metric will consistently be low (maybe 5%), when in actuality, the system is only using 50% of the RAM.
It is possible in Sightline EDM to accurately monitor Linux memory usage and generate alerts when the amount of real memory gets too low, as opposed to when the default Mem % Free metric only appears to be too low.
Currently, this needs to be done using an expression, which lets you build and define your own metrics using currently existing metrics. We will make 2 expressions in order to monitor real Linux memory usage.
By using these expressions, it is possible to create meaningful alerts based on real memory instead of the default Mem % Free across a wide range of Unix systems.
The screenshot below shows the default Linux memory metric, Mem % Free, in the lower blue line hovering around 1% free, in comparison with the expression created for Mem Real pct Free, which shows the upper orange line around 36% free. Although the blue line appears to indicate that the Linux system is out of memory, that memory is actually being used for disk caching, whereas the orange line shows real memory around 36% free, which is a much better metric for creating performance alerts.
The difference can also be seen at the end of the graph, when an application begins using real memory, causing the orange line to dip down to 5%. The blue line does not reflect this change, however, because the system simply decreases the amount of memory available for disk caching and increases the amount of memory availabile to other applications, which effectively cancels each other out. In this way, it is possible to set up alerts to accurately monitor Linux memory usage in Sightline EDM’s IT Infrastructure monitoring system.
The Industrial Internet of Things (IIoT) is changing the landscape of the U.S. manufacturing industry. Companies that understand the patterns and trends and position themselves to prepare for the impending advances will most certainly gain a competitive edge in the global marketplace.
Companies no longer have the luxury of being anything but data-driven. Data used to be something to simply maintain and manage, but now it’s a valuable asset that companies use to gain a competitive edge. With change happening so rapidly, how are manufacturers preparing to take advantage of the massive amounts of data that is available and more importantly, how are they using that data to really take advantage of the power that IIoT delivers?
When posing the question of how manufacturing companies are preparing for IIoT, many manufacturing leaders think of IIoT as something far off in the distance, but they don’t really understand the full impact that is coming. Many see it as a fad or something that may only have some effect on the way they handle day-to-day operations in the long run. As we begin to peel back the layers of IIoT, one sees that there is a strong potential for a shift to occur that will change the entire manner in which manufacturing companies operate similar to what the manufacturing industry saw when they were first implementing automation and began using IT and other electronics. As a result, manufacturing leaders are seeking to develop formal and informal IIoT strategies that will position their companies to take advantage of new opportunities to streamline efficiencies, reduce downtime and stimulate profitability sooner rather than later.
If one reviews the history of manufacturing, there are four distinct manufacturing industrial revolutions spanning from the initial mechanical production facilities to mass production to use of electronics and IT to IIoT and systems integration. The fourth industrial revolution, or Industry 4.0, will allow manufacturers to leverage the Industrial Internet of Things (IIoT) to collect vast amounts of sensor and network data, apply advanced analytics and further utilize new technology such as robots and 3-D printing to improve quality and output.
While some progressive manufacturers see where the industry is headed, many are only at the starting gate of the next wave of innovation fueled by IIoT applications and solutions. According to a recent study by Smart Industry, many manufacturers are focused on learning and benchmarking to formulate winning strategies. Many will be using the findings to reduce operational costs, optimize asset utilization, improve worker productivity, enhance workplace safety, enhance the customer experience and create new business models and revenue streams.
The best way for the manufacturing industry to capitalize on IIoT is by gathering more data from sensors and systems and utilizing it to make business-driven decisions. While that may seem as though it is not an easy task, by adding advanced analytics solutions now, manufacturers will most certainly have more “a-ha” moments as they produce insights previously clouded by uncertainty or unattainable due to limited resources and time.
The advanced platforms will enable manufacturers to gather the right data, at the right time which can be leveraged to make well-informed, and most importantly, proactive business decisions. These tools will provide more insight and will enable manufacturers to develop a major engine to identify and create new products, services and profit centers all while simultaneously improving production efficiency, reducing costs, preventing downtime, ensuring quality and enhancing their overall ability to strategically plan business operations.
Data is being collected by sensors, PLCs and more to the point some manufacturers are overwhelmed with data and aren’t really sure where to start. With so much data readily available, many manufacturers are wondering how to start implementing IIoT technologies in a thoughtful manner. Many manufacturers are taking a very close look at the data they want to collect and how they will use the information to streamline efficiencies, realize opportunities and produce a sizeable return on investment (ROI).
Manufacturers are concerned by a host of obstacles for adopting IIoT in their companies, with the most notable being cybersecurity. Cybersecurity concerns, lack of overall IIoT knowledge internally, legacy products that do not have obvious IIoT connectivity and lack of senior management support and commitment, just to name a few, are among the most pressing issues that keep manufacturers up at night. In order to wrap their arms around these challenges, proactive manufacturers will need to gain a better understanding of how to leverage advanced analytics. The traditional manufacturing business model is quite reactive and relies on management to be the primary driver of change, production that is driven by a sales forecast, and system improvements if, and only if, it is perceived to be “broken.” As the manufacturing landscape advances due to IIoT, manufacturers must begin to take a more holistic view of the entire company to better understand how one part of the operation affects other parts in order to take advantage of enormous opportunities for improvement and to proactively gain the competitive edge.
As manufacturers begin to take a more holistic approach, many are working with internal teams, suppliers and consultants to decide the most valuable data to collect, what systems require enhancement, how the data will help them realize opportunities as well as how to gauge the full impact of IIoT changes within and outside the company. The two most critical issues are data management and cybersecurity. These areas will be critical challenges for the company to address as it affects future competitiveness
IIoT is most definitely changing the landscape of the manufacturing industry as we know it. Manufacturers that read the trends, understand data patterns and begin to lay the foundation now to proactively take advantage of the technological advances will be poised to remain viable in the global marketplace throughout the decades to come.

INTEGRIS Health is Oklahoma’s largest state-owned health system, with hospitals, rehabilitation centers, physician clinics, mental health facilities, independent living centers, and home health agencies throughout the state. With a wide, interconnected network and much sharing of information between facilities, it is crucial that their IT network service levels ensure constant network availability in order to provide superior client response time. Sightline is being used to monitor the operating systems and hardware of INTEGRIS Health’s network. Ted Kidd, Systems Engineer for INTEGRIS Health, explained that the organization needed a tool to track overall system performance and utilization. In particular, they needed a monitoring solution for their OpenVMS platform. After looking at different vendors, including PAWZ, the company decided that Sightline would best serve their complex needs based on Sightline’s drill-down capabilities and ability to monitor server performance 24×7.
Kidd explained that Sightline has provided INTEGRIS Health with accurate historical information, as well as timely day-to-day information. It has eliminated guesswork about requirements for hardware and has allowed INTEGRIS Health to spot and analyze problems quickly and efficiently. In addition to covering their OpenVMS platform, Sightline has enabled INTEGRIS Health to monitor their Tru64 and AIX environments, fostering interrelationships between these critical systems. By using history trace files and offering the data on their internal web using Sightline’s AutoWeb, INTEGRIS Health has been able to better track server activity and actually see growth trends.
This is crucial to their systems engineers as well as management, who are able to access information for analysis in an easy and timely manner. As an example, Kidd cited a recent instance in which a message was received from their Tivoli monitor that the CPU of one of their servers was extremely busy. When they received the message, they pulled up the Sightline live feed plot for that server (which is offered up via AutoWeb). Because of this advanced monitoring feature of Sightline, Kidd was able to go to the web page for live plots and see that the CPU was pegged at 100% for the past 30 minutes. Kidd was able to work with the application/database analyst, find the cause of the problem, and resolve the issue. Sightline provided the means to see it all, enabling managers to implement performance rules and logic that automatically scanned all components of the critical transaction path in real-time to ensure complex operations remained contention free, and to assure service level standards.
Value Created for Executives and End Users:
With Sightline, INTEGRIS Health experiences value at all levels of the organization.

Sightline enables you to view end-to-end business flows and view service level indicators in real-time. An organization is able to maintain peak performance of its applications and the systems supporting them.
“We needed service level assurance across the many levels of our enterprise. Sightline makes a significant difference in our overall operations efficiency,” commented Ted Kidd, Systems Engineer, Integris Health management of the business critical IT infrastructure. Now organizations can easily identify trends and relationships in key business indicators as they are occurring, not after they have reached a critical threshold. Furthermore, Sightline can quickly and automatically determine the root causes which are contributing to any service level degradation and enable IT to address the issues before end-users experience any service interruptions.
Business in the highly competitive financial services industry has always been about providing the customer with the best possible service to ensure their patronage. Scottish Life recently received recognition for the management of customer facing IT systems and services. Compass Management Consulting, a fact-based performance improvement consultancy, awarded Scottish Life a place in the Top 20 world group of best performing companies in 2001, based on the speed and efficiency of its IT systems development and networks. “There is no question that financial services companies must rely more and more on highly efficient IT systems to help provide quality service to customers at minimum cost. Over the years, Scottish Life has invested prudently but significantly in this area, and we will continue to do so to help ensure that Independent Financial Advisors (IFAs) and their clients receive the kind of service they would want from us,” said Brian Duffin, chief executive of Scottish Life.
Prior to a major strategic infrastructure enhancement, Scottish Life faced significant obstacles in maintaining service levels. When Scottish Life’s original systems encountered service degradations, the resolution process began by users making a phone call to technical staff. Resolution of problems often resulted in significant delays as the technical staff waded through pages of figures. By the time the issue was resolved, the problem had often become much worse and the provision of service was greatly impacted. The lack of adequate measures to rapidly identify faults in the system led Scottish Life to seek greater reassurance in a resilient, structured solution.
Scottish Life viewed three competing systems’ monitoring tools before selecting Sightline™. After installing Sightline for a trial period, the software detected a major glitch that enabled Scottish Life to solve a significant problem prior to launch of a major new system. In addition, the graphic interface of Sightline made fault diagnosis easier to identify than with the competing products. Sightline’s performance quickly proved its value and was promptly installed across Scottish Life’s infrastructure.
Approximately 200,000 financial transactions are processed daily throughout Scottish Life’s IT infrastructure, with its primary service window operating between the hours of 8 am and 8 pm. At any given time, the system is capable of handling one thousand users, with the number stabilizing at between three to four hundred users at a time. Due to its advancements with Sightline, Scottish Life is now able to provide its computer users with service level agreements (SLAs) guaranteeing ninety-nine percent operational uptime.
