Why I Enthusiastically Switched from Cacti to Zabbix for System Monitoring

Cacti is a “complete network graphing solution” according to their website. It has also been a thorn in my side for a long time.

See what I did there? Thorn… because it's a cactus… never mind.

When Cacti is in a steady state-when I could get it to a steady state-it was good. Not great, because there was a lot of effort to get it into what I consider “steady state”, but good. The rest of the time… thorny.

There are five major things that have driven me up the wall. In no particular order:

IBM’s hub for wearables could have you out of the hospital faster

Researchers at IBM have developed a hub for wearables that can gather information from multiple wearable devices and share it with a doctor, potentially cutting down on the time patients need to spend in a hospital.The gadget, which IBM has dubbed a 'cognitive hypervisor,' funnels data from devices such as smart watches and fitness bands into the IBM Cloud. There, it's analyzed and the results are shared with the user and their doctor.The idea is that patients can be monitored reliably through the device so they can be sent home to recover from illnesses a day or two earlier than they might otherwise have been allowed. It also means that should a problem develop, a doctor can be alerted immediately and an ambulance dispatched if it's serious enough.To read this article in full or to leave a comment, please click here

SkyBell HD, the best video doorbell so far

Some time ago I wrote about the Ring doorbell and concluded, as I wrote in a subsequent review of the company’s Stick Up Cam, that “While I liked the product conceptually, the startup lag (the time between detecting movement and when recording begins, usually a delay of a few seconds) is long enough that fast moving people like the Fedex guy can come and go before the device starts recording” and I lamented the so-so video quality. To read this article in full or to leave a comment, please click here

BrandPost: 12 ideas for advanced DevOps practices

If your organization has adopted a DevOps initiative, you’re likely already seeing improvements in culture and processes. Maybe you’ve automated manual tasks, built a continuous delivery pipeline, and improved collaboration between Dev and Ops. Team morale has gone up, and the number of 3 AM calls has gone down. You’re doing really well compared to many other organizations.Of course, DevOps is not one-and-done; it’s an ongoing journey. There’s always a way to achieve greater control, predictability and flexibility.Continuous Improvement is a new ebook by Puppet for anyone who's already tackled the fundamental DevOps practices and wants to go further. You’ll learn tips on improving cross-departmental collaboration, holding internal events like workshops and hackathons, and building in metrics and transparency to hold everyone accountable.To read this article in full or to leave a comment, please click here

Juggling Applications On Intel Knights Landing Xeon Phi Chips

Intel’s many-core “Knights Landing” Xeon Phi processor is just a glimpse of what can be expected of supercomputers in the not-so-distant future of high performance computing. As the industry continues its march to exascale computing, systems will become more complex, and evolution that will include processors that not only sport a rapidly increasing number of cores but also a broad array of on-chip resources ranging from memory to I/O. Workloads ranging from simulation and modeling applications to data analytics and deep learning algorithms are all expected to benefit from what these new systems will offer in terms of processing capabilities. …

Munich’s great Linux desktop initiative may end

A decade ago, there was much hoopla over the city of Munich discarding Windows desktops in favor of Linux, which were thought to be more secure and cheaper to deploy and maintain. Well, that experiment is coming to an end. TechRepublic reports the city is prepared to shift gears and allow users once again to choose Windows for their work PC instead of Linux after complaints of poorer productivity and compatibility issues. But it's not going to happen overnight; the Windows option won't come until 2021. To read this article in full or to leave a comment, please click here

Microsoft shelves all February security updates

Microsoft today took the unprecedented step of postponing an entire month's slate of security updates for Windows and its other products just hours before the patches were to begin rolling out to customers."We discovered a last-minute issue that could impact some customers and was not resolved in time for our planned updates today," Microsoft said in a post to the MSRC (Microsoft Security Research Center) blog. "After considering all options, we made the decision to delay this month's updates."Today was set as Patch Tuesday, the monthly release of security fixes from Microsoft. Normally, Microsoft issues the updates around 10 a.m. PT (1 p.m. ET). Although Microsoft did not time stamp its blog post, the SAN Institute's Internet Storm Center (ISC) pointed out the delay at 8:22 a.m. PT (11:22 ET).To read this article in full or to leave a comment, please click here

Response: Network Icons – ‘net work

These are great icons for network diagrams from Russ White. Much more useful for all diagrams purposes than most other icons.

I’ve developed this set of vendor neutral network icons for drawing diagrams in presentations, books, and the like. I’m placing them here in the public domain in four different formats

Network Icons – ‘net work : http://rule11.us/net-icons/

Personally, I use simple shapes and colours for my diagrams for simplicity but I suspect these will appeal to people who are Visio-centric in their workflow.

Juniper facing fatal clock flaw that impacts Cisco routers, switches

The fatal clock timing flaw that causes a variety switches, routers and security appliances to crash and die after about 18 months of service is apparently part of some Juniper products.Cisco was the first vendor to post a notice about mortal clock fail earlier this month saying the notice includes some of the company’s most widely deployed products, such as certain models of its Series 4000 Integrated Services Routers, Nexus 9000 Series switches, ASA security devices and Meraki Cloud Managed Switches. Clock components are critical to the synchronization of multiple levels of a given device.+More on Network World: Cisco: Faulty clock part could cause failure in some Nexus switches, ISR routers, ASA security appliances+To read this article in full or to leave a comment, please click here

Worth Reading: IBM should buy…

We spend a lot of time contemplating what technologies will be deployed at the heart of servers, storage, and networks and thereby form the foundation of the next successive generations of platforms in the datacenter for running applications old and new. While technology is inherently interesting, we are cognizant of the fact that the companies producing technology need global reach and a certain critical mass. —The Next Platform

Docker Love

We wanted to hear from the community about why they love Docker!

Wellington Silva, Docker São Paulo meetup organizer said “Docker changed my life, I used to spend days compiling and configuring environments. Then I used to spend hours setting up using VM. Nowadays I setup an environment in minutes, sometimes in seconds.”


Docker Santo Domingo organizer, Victor Recio said, “Docker has increased my effectiveness at work, currently I can deploy software to production environment without worrying that Continue reading
