The Apache HTTP Server (Apache HTTPd) is one of the most popular open source web servers available. HTTPd was also the first project developed by the Apache Software foundation which now supports hundreds of well known projects including Kafka, Cassandra and Hadoop. Netdata has a public demo space where you can explore different monitoring use-cases. Check out the Apache demo room to explore and interact with the charts and metrics described here.

Web servers are among the most important components in modern IT infrastructures. They host the websites, web services, and web applications that we use on a daily basis. Social networking, media streaming, software as a service (SaaS), and other activities wouldn’t be possible without the use of web servers. And with the advent of cloud computing and the movement of more services online, web servers and their monitoring are only becoming more important.

In this article, we are going to look at how to monitor Redis performance using Prometheus. This will allow Redis Administrators to centrally manage all of their Redis clusters without setting up any additional infrastructure for monitoring. To follow the steps in this blog, sign up for the MetricFire free trial, where you can use Graphite and Grafana directly on our platform.

In this article, we present an overview of cluster monitoring using Rancher and Prometheus as well as provide some brief setup tutorials for both tools. We further introduce a metric visualization tool called Grafana that transforms your Prometheus time-series data into graphs and visualizations. MetricFire specializes in monitoring systems. You can use this product with minimal configuration to gain in-depth insight into your environment.

Security is one word that is at the tip of everyone’s tongue when it comes to ensuring that web browsers are up to date. In August 2022, after zero day vulnerability CVE-2022-2852 was identified as a critical risk, Google issued a new set of Chrome security updates and tech-industry folks carried on with business as usual. In general, security vulnerabilities of all types are an all-too-common game of Whac-A-Mole. Once a security flaw is discovered and patched, another pops up to take its place.

Latency is the key differentiator when it comes to application performance on the internet. Reduced latency accelerates the delivery of apps. DNS resolving is the first step towards application delivery and it involves a series of steps. Prior to Anycast DNS, the DNS servers responsible for resolving users’ DNS requests were sitting continents away from many users, contributing to the high latency and slow delivery of applications.

Many people wonder what the difference is between monitoring vs. observability. While monitoring is simply watching a system, observability means truly understanding a system’s state. DevOps teams leverage observability to debug their applications or troubleshoot the root cause of system issues. Peak visibility is achieved by analyzing the three pillars of observability: Logs, metrics and traces.
