Using Red Hat Insights as a source of events for Event-Driven Ansible automation

insights and event driven blog

One of the key announcements at AnsibleFest 2022 was the introduction of the Event-Driven Ansible developer preview. This technology is currently available on GitHub and accessible by technology providers and end users to provide feedback and drive the ecosystem. ISVs and consulting/service partners are specifically invited to create event driven automation content that makes it easy for customers to use in joint solutions.

 

Red Hat Insights events as a source for Event-Driven Ansible

Red Hat Insights, is a managed service that is included in every Red Hat subscription. It continuously analyzes platforms and applications to help enterprises manage hybrid cloud environments, and can trigger events through its Notifications service. Each account configures how and who can receive these events, with the ability to perform actions depending on the event type. For example, one may want to forward new recommendations found for Red Hat Enterprise Linux (RHEL) system configuration to a specific team by email, and/or create a new ticket in ServiceNow for the Operations team to handle. Others may want to forward all triggered events to Splunk for external analysis and troubleshooting. Through its Integrations service, Insights provides end-point integrations to Splunk, ServiceNow, Slack, as well as Continue reading

AWS boosts its infrastructure for memory-intensive tasks

Amazon Web Services (AWS) has announced availability of its new Amazon EC2 M7g and R7g instances, the latest generation of instances for memory-intensive applications and running Amazons custom Arm processor, known as Graviton3.This is the second offering of Graviton3-based instances from AWS. It previously announced specific instances for compute-intensive workloads last May.Both the M7g and the R7g instances deliver up to 25% higher performance than equivalent sixth-generation instances. Part of the performance bump comes from the adoption of DDR5 memory, which offers up to 50% higher memory bandwidth than DDR4. But there’s also considerable performance gain from the new Graviton3 chip.To read this article in full, please click here

Tailoring your Linux command prompt

The command prompt in a Linux terminal window is often just a $ unless you’ve logged in or sudo’ed your way into the root account, in which case you'd expect a #.Sometimes, though, your prompt will be more complicated, with a format like [lucky@fedora ~]$. But it's possible to change your prompt to some friendlier character, word, or phrase, and if you’re so inclined, you can even change its color. This post shows how easy it is to make these kinds of changes.Changing the format To get started, one thing you need to know is that your command prompt is not just something your shell creates on the fly. Instead, it’s a variable and its name is PS1. To see how your prompt is defined, display its value like this:To read this article in full, please click here

Wi-Fi HaLow: Wireless for the internet of things

Wi-Fi HaLow, the marketing term the Wi-Fi Alliance has chosen for the IEEE 802.11ah standard, is a long- range, low-power, low-speed version of traditional Wi-Fi. It shows promise with deployment of Internet of Things (IoT) devices such as sensors, wearables, machine-to-machine (M2M) applications, smart buildings, and smart cities.With the ability to connect low-bandwidth devices to IP networks including the internet, it supports enough bandwidth to handle HD-quality video and can even be used for rural communications and offloading cell phone tower traffic.To read this article in full, please click here

Measuring Virtual Network Device Boot Times

A senior engineer at Juniper Networks wasn’t happy with me mentioning resource hogs and Junos platforms in the same statement. Instead of engaging in never-ending angels dancing on pins deliberations comparing the virtues of Junos with other network operating systems, I decided to throw a bit of real-life data into the mix – I created a simple script that measures:

  • The time it takes to execute vagrant up to start a single network device.
  • The time it takes to deploy simple initial configuration on that device.

Server DRAM to exceed mobile DRAM, as enterprises adopt emerging tech

Semiconductor manufacturers will respond to changes in demand by producing more dynamic RAM (DRAM) for servers than for mobile devices this year, a milestone that highlights increasing enterprise use of emerging technology related to cloud computing, AI and high performance computing (HPC) applications, according to market research firm TrendForce.To handle the emerging-tech workloads, the average DRAM content of servers will increase by 12.1% year-over-year in 2023, compared to an increase of 6.7% for DRAM content for smartphones, TrendForce forecasts. DRAM content refers to the amount of DRAM memory installed in a device.In a related estimate, server memory is expected to make up 37.6% of what TrendForce determines to be the total bit output of DRAM semiconductors, compared to mobile DRAM’s 36.8%, the company said in its latest DRAM research report.To read this article in full, please click here
