For application developers and service owners who build and troubleshoot modern enterprise software, resolving production issues requires identifying poor performance across multiple networks, operating systems, servers, configs, and third party dependencies. When the problem is the code itself, code profiling helps identify service bottlenecks by periodically taking CPU snapshots, or call stacks, from a runtime environment.

Last week, we celebrated the Ubuntu 21.10 release on the Ubuntu On Air channel, where a wide range of guests discussed their Impish Indri highlights as well as some thoughts for the future. Today we thought we would share ours! For Linux desktop users, Impish Indri contains a number of new features plus a preview or two for you to try out ahead of our LTS release next year with 22.04. So here are our top 5 must try for Ubuntu Desktop 21.10.

We just announced the creation of a new RemoteWrite SDK to support custom metrics from applications using several different languages. This tutorial will give a quick rundown of how to use the Java SDK. This SDK – like the others – is completely free and open source, and is meant to apply to any output destination, not just Logz.io.

The cloud not only ushered in a different way of developing and deploying software, but it also introduced a fundamentally different security reality, presenting new challenges to teams responsible for keeping environments secure. Designed to be dynamic, cloud environments can be in a near-constant state of change, with infrastructure resources spun up and down multiple times a day to support cloud applications.

We’re excited to announce the general availability of the LogDNA Agent 3.3, which introduces Linux and ARM64 support to our Rust Agent. This new support in our Rust Agent provides improved performance and enables a few features previously only available for our Kubernetes customers, such as various configurations within the Agent and the ability to run as a non-root user. Additionally, we have added in Prometheus Metrics that help provide insights into your Agent.

We all know the importance of cataloging, organizing, and breaking down the data in your logs. That process, parsing, makes information easier to find and simplifies subsequent analysis. Now, with Logz.io’s upgraded self-parsing tool, custom parsing rules, and log organization is easier than ever. What’s important is parsing that data out correctly. The better parsed, the easier to query.

Version 2.4 improves its e2e tests, revamps how logging in the HAProxy Data Plane API works, adds support for namespace filtering in Consul Service Discovery, improves runtime capabilities for maps and ACLs, adds server-template support and adds log_targets to global and defaults sections.

Thanks to a lot of hard work and excellent feedback from the open source community, Mattermost v6.0 is now generally available! This is a major platform upgrade with new capabilities and wider use case coverage, which many server administrators will be eager to take advantage of. Due to the scope of the changes introduced in v6.0, admins will want to plan ahead for a bit of downtime, especially for larger database migrations. Here’s a rundown of what’s new and what to expect.

Calico Cloud is an industry-first security and observability SaaS platform for Kubernetes, containers, and cloud. Since its launch, we have seen customers use Calico Cloud to address a range of security and observability problems for regulatory and compliance requirements in a matter of days and weeks. In addition, they only paid for the services used, instead of an upfront investment commitment, thus aligning their budgets with their business needs.

14 October 2021: Today, Canonical released Ubuntu 21.10 – the most productive environment for cloud-native developers and AI/ML innovators across the desktop, devices and cloud. “As open source becomes the new default, we aim to bring Ubuntu to all the corners of the enterprise and all the places developers want to innovate,” said Mark Shuttleworth.
