Introduction to Grafana Plugins

Grafana is a powerful open-source platform for monitoring and observability, but what truly makes it shine are its plugins. For technology engineers looking to expand Grafana's capabilities, plugins are the way to go. In this post, we'll dive into the world of Grafana plugins and offer some unique tips to get the most out of them.

Coralogix vs Grafana Cloud: Pricing, Features and More

While Grafana is one of the better known names in the industry, Coralogix offers a full-stack observability platform. Despite the popularity of the Grafana brand, the cloud based solution lacks in some key areas. This article will go over the differences between Coralogix and Grafana Cloud, from features, customer support, pricing and more.

Can You Use the ELK Stack as a SIEM? A Fresh Take

A SIEM system (Security Information and Event Management) is often used by security operations centers (SOCs) for real-time detection of suspicious activity and security events. While some teams choose to adopt a purpose-built SIEM, others rely on the same DevOps tools they are already using for tasks like troubleshooting and operational log data analysis.

Elasticsearch to OpenSearch Migration Facilitated by Sematext Cloud

OK, so you’ve decided to move from Elasticsearch to OpenSearch. Maybe our comparison helped you decide and maybe you’ve checked our guide on how to perform the migration. But how do you know if your new OpenSearch performs as well and functions as correctly as the existing Elasticsearch? Even when comparing old with new versions, upgrades don’t always translate into better performance.

Is a $1 million Datadog bill worth it?

In a recent reddit thread, I got into a conversation about justifying the cost of observability. It got to a really basic question about running a tech company: how do you know that any cost is justified? While a small number of expenses have clear and direct business values, a bunch of other costs, I would even say most costs, just aren’t that clear cut.

Migrating 1 billion log lines from OpenSearch to Elasticsearch

What are the current options to migrate from OpenSearch to Elasticsearch®? OpenSearch is a fork of Elasticsearch 7.10 that has diverged quite a bit from itself lately, resulting in a different set of features and also different performance, as this benchmark shows (hint: it’s currently much slower than Elasticsearch).

An Overview of the Essential Observability Metrics

Metrics are closely associated with cloud infrastructure monitoring or application performance monitoring – we monitor metrics like infrastructure CPU and request latency to understand how our services are responding to changes in the system, which is a good way to surface new production issues. As many teams transition to observability, collecting metric data isn’t enough.

Predictive Maintenance: A Brief Introduction

Predictive maintenance is a maintenance strategy that uses machine learning algorithms trained with Industrial Internet of Things (IIoT) data to make predictions about future outcomes, such as determining the likelihood of equipment and machinery breaking down. Using a combination of data, statistics, machine learning and modeling, predictive maintenance is able to optimize when and how to execute maintenance on industrial machine assets.
