Second.The results write to the /var/run/cumulus/histogram_stats snapshot file.When the queue length reaches 500 bytes, the system sends a message to the /var/log/syslog file and collects additional data; buffer occupancy and all packets per port.Buffer occupancy data writes to the /var/lib/cumulus/buffer_stats snapshot file and all packets per port data writes to the /var/lib/cumulus/all_packet_stats snapshot file.In addition, packet drops on swp1 through swp50 collect every two seconds. If the number of packet drops is greater than 100, the monitor writes the results to the /var/lib/cumulus/discard_stats snapshot file and sends a message to the /var/log/syslog file.monitor.port_group_list = [histogram_pg,discards_pg]monitor.histogram_pg.port_set = swp1-swp50monitor.histogram_pg.stat_type = buffermonitor.histogram_pg.cos_list = [0]monitor.histogram_pg.trigger_type = timermonitor.histogram_pg.timer = 1smonitor.histogram_pg.action_list = [snapshot,collect,log]monitor.histogram_pg.snapshot.file = /var/run/cumulus/histogram_statsmonitor.histogram_pg.snapshot.file_count = 64monitor.histogram_pg.histogram.minimum_bytes_boundary = 960monitor.histogram_pg.histogram.histogram_size_bytes = 12288monitor.histogram_pg.histogram.sample_time_ns = 1024monitor.histogram_pg.log.queue_bytes = 500monitor.histogram_pg.collect.queue_bytes = 500monitor.histogram_pg.collect.port_group_list = [buffers_pg,all_packet_pg]monitor.buffers_pg.port_set = swp1-swp50monitor.buffers_pg.stat_type = buffermonitor.buffers_pg.action_list = [snapshot]monitor.buffers_pg.snapshot.file = /var/lib/cumulus/buffer_statsmonitor.buffers_pg.snapshot.file_count = 8monitor.all_packet_pg.port_set = swp1-swp50monitor.all_packet_pg.stat_type = packet_allmonitor.all_packet_pg.action_list = [snapshot]monitor.all_packet_pg.snapshot.file = /var/lib/cumulus/all_packet_statsmonitor.all_packet_pg.snapshot.file_count = 8monitor.discards_pg.port_set = swp1-swp50monitor.discards_pg.stat_type = packetmonitor.discards_pg.action_list = [snapshot,log]monitor.discards_pg.trigger_type = timermonitor.discards_pg.timer = 2smonitor.discards_pg.log.packet_error_drops = 100monitor.discards_pg.snapshot.packet_error_drops = 100monitor.discards_pg.snapshot.file = /var/lib/cumulus/discard_statsmonitor.discards_pg.snapshot.file_count = 16Bandwidth GaugeCumulus Linux supports the bandwidth gauge option on the Spectrum-4 switch only.To track bandwidth usage for an interface, you can enable the bandwidth gauge option with the nv set interface telemetry bw-gauge enable on command:cumulus@switch:~$ nv set interface swp1 telemetry bw-gauge enable oncumulus@switch:~$ nv config applyTo disable the bandwidth gauge setting, run the nv set interface telemetry bw-gauge enable off command.To show the bandwidth gauge setting for an interface, run the nv show interface telemetry bw-gauge command:cumulus@switch:~$ nv show interface swp1 telemetry bw-gauge operational applied------ ----------- -------enable on onTo show a summary of the bandwidth for an interface, run the nv show service telemetry bw-gauge interface command:cumulus@switch:~$ nv show service telemetry bw-gauge interfaceInterface Tx (Mbps) Rx (Mbps)--------- --------- ---------swp1 4 4SnapshotsTo create a snapshot:Set how often to write to a snapshot file. The default value is 1 second.Provide the snapshot file name and location. The default location and file name is /var/run/cumulus/histogram_stats.Configure the number of snapshots to create before Cumulus Linux overwrites the first snapshot file. For example, if you set the snapshot file count to 30, the first snapshot file is histogram_stats_0 and the 30th snapshot is histogram_stats_30. After the 30th snapshot, Cumulus Linux overwrites the original snapshot file (histogram_stats_0) and the sequence restarts. The default value is 64.Snapshots provide you with more data; however, they can occupy a lot of disk space on the switch. To reduce disk usage, you can use a volatile partition for the snapshot files; for example, /var/run/cumulus/histogram_stats.The following example creates the /var/run/cumulus/histogram_stats snapshot every 5 seconds. The number of snapshots that you can create before the first snapshot file is overwritten is set to 30.NVUE Commandscumulus@switch:~$ nv set service telemetry snapshot-file name /var/run/cumulus/histogram_statscumulus@switch:~$ nv set service telemetry snapshot-file count 30cumulus@switch:~$ nv set NVIDIA® Cumulus Linux is the first full-featured Debian bookworm-based, Linux operating system for the networking industry.This user guide provides in-depth documentation on the Cumulus Linux installation process, system configuration and management, network solutions, and monitoring and troubleshooting recommendations.

Of Open Networking Reduced Total Cost of Ownership (TCO) With less downtime and more switches per operator, open networking saves you substantially on operating expenses. In fact, according to our own study, customers can save up to 60 percent on TCO by switching to open solutions. Faster Troubleshooting Closed solutions force you to rely entirely on the vendor. So when something goes wrong with the network, you’re dependent on the vendor’s ability to fix the problem. Open networking, with its active community, enables you to research the problem and find the solution. Simplified Configuration Once you get the hang of Linux, configurations become much easier and intuitive. If you'd like to see for the differences between traditional and Linux networking in action, head over to our web-scale networking how-to videos Scalability As you build out your data center, you’ll need a network that can grow with the changes you make. Open networking allows you to build to the scale of your company, whether you’re a small startup or a cloud giant. Faster Time to Market With fast and easy deployment, open networking gives you a much quicker time to market. In fact, switching to open networking can increase operational efficiency and reduce time to deployment by 95%. Automation Automation eliminates the need to engage in repetitive tasks and decreases the margin of human error. It saves time and energy, and increases the ratio of switches to operator. Get Involved in the Linux Community With over 6 million lines of code and more than 1,000 active contributors, the Linux kernel is a community-based effort to keep Linux fresh and evolving. Becoming involved with the Linux kernel and writing code is a great way to contribute to the community. In fact, NVIDIA has contributed to the kernel with the addition of virtual routing and forwarding (VRF) and the network interface manager ifupdown2.

Those who want to get up and running fast or don't need as much customizability. Key SDN controller vendors and offerings When using an SDN controller, admins have access to the entire software-defined network. This poses some security and redundancy challenges. Thoroughly assess infrastructure and network needs when choosing a vendor or controller. SDN controller vendors and products include the following: Big Switch Networks Cisco Cumulus Networks HPE Juniper Networks Nuage Networks Pica8 Pluribus Networks VMware Open source options include the following: Beacon Floodlight NOX/POX Open Network Operating System Open vSwitch OpenDaylight Ryu Trema Tungsten Fabric, formerly OpenContrail While admins may only need one SDN controller, organizations can use more than one in case of a failure or in the event someone gains access who shouldn't. Deploying and operating an SDN controller Configuration is the biggest hurdle when it comes to deploying an SDN controller. Typically, admins need to configure the entire network when transitioning to a software-defined architecture. In this case, configuring the SDN controller software is at the heart of the process and requires admins to install the protocols they want to use. Configuration takes time, but the benefits of centralized network management make up for it. Adding controllers differs by vendor, especially with the lack of standards in SDN controllers. Ideally, configure the network with multiple controllers in mind. Otherwise, the process may require some reconfiguration, which is not always easy. That said, operating a software-defined network through a controller is simple. Admins can optimize hardware from one point of control, make changes on the fly and scale infrastructure easily. Resource provisioning is simple compared to the traditional network methods. All communications must go through the control layer, and as such, the controller is a critical piece of any software-defined network. With this background information and knowledge of the key offerings to look for, admins can make a better-informed decision to choose the type of SDN controller to use in the data center. These decisions directly impact everything from performance to security and redundancy. Dig Deeper on Data center hardware and strategy OpenFlow By: Gavin Wright SDN

Cumulus VX 3.4.3 Release Notes – Cumulus Networks

Part of being able to forecast comes from reading the sky, because so much of what’s taking place in the atmosphere can be seen visually. When I worked the forecast counter in the Air Force, I occasionally stepped over to the window for a quick look while filling out the weather briefing forms. The pilots often caught notice of this. I remember one B-1B Lancer pilot who turned to his fellow crewmembers and said, “Now that’s what I like to see! This forecaster doesn’t miss anything.”When taking in visual clues, forecasters look for signs of wind behavior, dust plumes, haze layers, patches of fog, unusual phenomena on the horizon, and the general appearance and color of the sky. But we most rely on the clouds and how they’re shaped and textured. When clouds are present there’s a lot of information at hand, and that’s what we’ll look at here.There are ten basic cloud types: cumulus, stratus, cumulonimbus, stratocumulus, nimbostratus, altostratus, altocumulus, cirrus, cirrostratus, and cirrocumulus. You’re probably already at least passingly familiar with these, and FAA AC 00-6B, Aviation Weather, touches on these different categories. Rather than sorting out clouds individually, we’ll take a slightly different approach and break down some of the common skyscapes that pilots encounter while flying.Fair-Weather CumulusThe fair-weather cumulus sky is marked by weakly vertical cumulus clouds with flat bases and high layer altitudes during the afternoon. Fair weather cumulus are quite common during the summertime in moderately stable air masses, in other words, where the lapse rate is weak and the temperature doesn’t fall very much with height. Weak lapse rates are often associated with an upper-level high. On winds-aloft charts you may see an anticyclone, or anticyclonic flow. Conditions above 10-20,000 feet MSL may be a bit warmer than usual.These highs are typically subtropical highs, such as those associated with the Bermuda High. As semi-permanent features, they’ll often park themselves over a region for weeks, giving the same weather day after day. On rare occasion the highs are cutoff highs, such as the one associated with the record-setting heat wave in the Pacific Northwest this past June. Those types of highs are much more short-lived, and after a few days, the weather reverts to more of a fastchanging, transitional pattern.If lapse rates are steeper, instead of fair weather cumulus we get skies filled with moderate cumulus (MDT CU) and towering cumulus (TCU). These are the last stages before showers and thunderstorms. Lower cloud heights than would otherwise be expected, and bases that remain ragged and fail to flatten out over time, are good indicators that conditions are deteriorating.CumulonimbusThe cumulonimbus cloud is the ultimate form of deep convection, in which a cumulus cloud grows through much of the troposphere while maintaining both an inflow that feeds the updraft, and outflow produced by precipitation. The photo on the top-right of the next page shows what happens below the base of a cumulonimbus cloud.Contrast this with a lot of photos you see on cloud charts showing the. Cumulus Networks.
