Getting started with PromQL - Includes Cheatsheet!

Getting started with PromQL can be challenging when you first arrive in the fascinating world of Prometheus. Since Prometheus stores data in a time-series data model, queries in a Prometheus server are radically different from good old SQL. Understanding how data is managed in Prometheus is key to learning how to write good, performant PromQL queries. This article will introduce you to the PromQL basics and provide a cheat sheet you can download to dig deeper into Prometheus and PromQL.

Log4j 2 Configuration Example: Tutorial on How to Use It for Efficient Java Logging

When it comes to troubleshooting application performance, the more information you have the better. Logs combined with metrics and traces give you full visibility into your Java applications. Logging in your Java applications can be achieved in multiple ways – for example, you can just write data to a file, but there are far better ways on how to do that, as we explained in our Java logging tutorial.

Monitoring Locations Update

Since June 2020, when we launched the new Monitive, we have the same monitoring network of 8 locations. It’s time to expand. The current locations are VPS servers from DigitalOcean and Linode. I like to mix it a bit, so that we don’t rely on a single provider, but not too much, since the administrative overhead of managing dozens of providers is another lesson learned in 10 years of uptime monitoring.

How we're gradually evolving to a new Uptrends

You might’ve noticed that things are looking a bit different in your account lately. We’ve been gradually rolling out updates to your dashboards and menus over the last months, and we will continue to improve the coming period. With these updates, we are upgrading the way you interact with Uptrends, so you can find stuff faster and visualize your data more easily.

VPN and Firewall Log Management

The hybrid workforce is here to stay. With that in mind, you should start putting more robust cybersecurity controls in place to mitigate risk. Virtual private networks (VPNs) help secure data, but they are also challenging to bring into your log monitoring and management strategy. VPN and firewall log management gives real-time visibility into security risks. Many VPN and firewall log monitoring problems are similar to log management in general.

TL;DR InfluxDB Tech Tips: Debugging and Monitoring Tasks with InfluxDB

With InfluxDB you can use Tasks to process data on a schedule. You can also use tasks to write custom alerts. However, sometimes your task will fail. In this TLDR, we’ll learn how to debug your task with the InfluxDB UI and the InfluxDB CLI.

Efficiently Monitor the State of Redis Database Clusters

Monitoring Redis, the open source in-memory data platform, is complicated enough when you are hosting your Redis instance on just a single server. It gets even more complex when you build a Redis cluster that consists of multiple nodes and distribute your data across them. But as long as you know which metrics to prioritize and how to collect them, Redis monitoring is feasible enough. This article offers an overview of how to monitor the state of Redis database clusters.

The Déjà Vu Evolution of Cloud Computing

I believe that the evolution to hybrid cloud is inevitable. Not because it’s grabbing headlines, but because it mirrors the industry’s history of new technology adoption. Take the evolution of virtualization, for example. Going back 20 years give or take, virtual machines popularized by VMware, KVM, and Hyper-V started to gain traction.

Why Observability Is the Key Ingredient to Success

Digital transformation is accelerating at a staggering pace. Consider these statistics. In December 2019, Splunk partner Zoom had 10 million monthly active users. By the end of last year, that number was estimated to be closer to 300 million. It was part of an explosion of technological growth replicated across many industries and businesses in 2020. As Splunk CEO Doug Merritt said.
