This year, we were excited to deliver the easiest version of Grafana Loki to use yet. With Loki 2.4, the Loki team introduced a simple, scalable deployment, and over the past 12 months, we added lots of great new features. Not to mention, we launched Grafana Enterprise Logs, a new addition to the Grafana Enterprise Stack that’s powered by Loki. But none of this would have been possible without our active community: In 2021, Loki had 166 contributors and 823 PRs in GItHub.

The Log4J library is one of the most widely-used logging libraries for Java code. On the 24th of November 2021, Alibaba’s Cloud Security Team found a vulnerability in the Log4J, also known as log4shell, framework that provides attackers with a simple way to run arbitrary code on any machine that uses a vulnerable version of the Log4J. This vulnerability was publicly disclosed on the 9th of December 2021.

Life is all about perspective, and the way we look at things often defines us as individuals, professionals, business entities, and products. How you understand the world is influenced by many details, or in the case of your application – many data sources. At Coralogix, we not only preach comprehensive data analysis but strive to enable it by continuously adding new ways to collect data.

If you have been trying to compare all of the best data visualisation tools you may have found it difficult to find a detailed list that includes both open-source and proprietary solutions to help you compare and make an informed decision on what you need going forward. In this guide, you will find out everything you need to know about the leading solutions for data visualisation to help you get started with your next analysis project.

While I write this blog post, I reflect on the years of being a system administrator and the task of ensuring that no sensitive data made its way past me. What a daunting task right? The idea that sensitive data can make its way through our systems and other tools and reports is terrifying! Not to mention the potential financial/contractual problems this can cause.

We are living in a data world. Data describes and controls almost every aspect of our life, from the president's elections to everyday grocery shopping. Data grows exponentially and so does the complexity of applications that manage that data. We all know the recent shift to microservices and other revolutionary changes that happened in the way we design, develop, deploy and operate modern applications.

On December 9, 2021, a vulnerability was reported that could allow a system running Apache Log4j 2 version 2.14.1 or below to be compromised and allow an attacker to execute arbitrary code on the vulnerable server. This vulnerability was registered on the National Vulnerability Database as CVE-2021-44228, with a severity score of 10. Here is a diagram of the attack chain from the Swiss Government Computer Emergency Response Team (GovCERT).

Interest in observability is at an all-time high. When we attended KubeCon in Los Angeles in October, observability and security were everywhere—in conversations with attendees and other vendors, during sessions, and in messaging at booths—indicating that there’s still an unmet need. In fact, Gartner declared that observability is at the ‘peak of inflated expectations' in a recent Hype Cycle report.

Logfile analysis plays a central role in enhancing the observability of your IT estate, helping operations teams and SRE engineers to identify issues as they emerge and track down the cause of failures quickly. As the number of log entries generated on any given day in a medium-sized business easily numbers in the thousands, viewing and analyzing logs manually to realize these benefits is not a realistic option. This is where automated real-time log analysis comes in.
