When working with CFEngine, it’s common to hear advice about separating data from policy. Separating data from policy allows for separation of concerns, delegation of responsibilities and integration with other tooling. Each organization is different, and a strategy that works well in one environment may not work as well in a similar environment of another organization, so CFEngine looks to provide various generic ways to leverage external data.
The Domain Name System (DNS) makes it possible for users to access websites using domain names, like wikipedia.org, in place of nine-digit IP addresses. Due to its ubiquitous nature, DNS can be used to block access to selected websites, which is commonly known as DNS filtering. Many companies see security and productivity benefits from implementing this strategy where appropriate. Read on as we explore some of the key details around how DNS filtering works and how it can be beneficial.
Observability has gained a lot of momentum and is now rightly a central component of the microservices landscape: It’s an important part of the cloud native world where you may have many microservices deployed on a production Kubernetes cluster, and a need to monitor these microservices keeps rising. In production, quickly finding failures and fixing them is crucial. As the name suggests, observability plays an important role in this failure discovery.
Sentry is an open source company. We started out in 2008 as a small open source side project, and we grew within the community for years before commercializing in 2012. We’ve worked hard to keep our full product as open source as possible, while scaling as a business. Considering our commitment to open source, we are grateful to be able to give back to the community (and what better time than during Hacktoberfest, amirite?). (P.S.
Prometheus is the industry standard in cloud native metric monitoring with hundreds of thousands of installations, millions of users, and billions in market value. Speaking as a member of the Prometheus team, we have seen the project become a victim of its own success. While most people may be using Prometheus, not everybody is following the same operating standards.
After trying several Prometheus exporters, I think I’m ready to fight the final boss: Monitoring a Windows cluster with Prometheus. I need a dashboard where I can monitor all the Windows machines in a single pane of glass. Let’s do it.
Kibana is the most popular open-source analytics and visualization platform designed to offer faster and better insights into your data. It is a visual interface tool that allows you to explore, visualize, and build a dashboard over the log data massed in Elasticsearch clusters. An Elasticsearch cluster contains many moving parts. These clusters need modern authentication mechanisms and they require security controls to be configured to prevent unauthorized access.
