Now available: Secure, real-time access to your observability data via Coralogix’s Model Context Protocol (MCP) Server. AI agents are only as powerful as the context they’re given. Today, we’re excited to announce the launch of the Coralogix MCP Server, which enables third-party AI agents to connect directly to your observability data across production, staging, and other environments.

IT leaders know the value of process improvement. Smoother onboarding, faster incident resolution, streamlined change management, etc. It’s not for lack of ideas that IT teams fall short; it’s almost always a lack of bandwidth. Because of that, most process improvement efforts stall before they scale. Great ideas get captured in diagrams, Confluence pages, and strategy decks, but they rarely make it into production. Why?

In today’s hospitals, technology is woven into every touchpoint of patient care. Nurses check vitals through digital monitors. Physicians review test results in the EHR. Medications get ordered, verified, and delivered through a network of connected systems. But when even one link in that chain fails, the impact isn’t just inconvenient—it’s dangerous. Downtime doesn’t just slow operations.

We are proud to announce that Splunk has been named a Leader in the 2025 Gartner Magic Quadrant for Observability Platforms for the third year in a row. In our opinion, our recognition in the Observability category comes on the heels of Splunk being recognized for a tenth consecutive time as a Leader in the 2024 Gartner Magic Quadrant for Security Information and Event Management (SIEM). Splunk was the only vendor named a Leader in both SIEM and Observability for the Gartner Magic Quadrant three times.

You're monitoring a microservices-based system. Alerts trigger when response times exceed 2 seconds. But when you open Jaeger, you're faced with thousands of traces. Identifying which service or operation is responsible becomes time-consuming. Jaeger metrics help reduce this friction by exposing aggregated telemetry. Instead of scanning individual traces, you get service-level and operation-level performance metrics, latency, throughput, and error rates that highlight where the issue lies.

Vertical Pod Autoscaling (VPA) is a component within Kubernetes designed to automatically resize the CPU and memory requests of pods based on their observed, historical usage patterns. While Pepperdata Capacity Optimizer and VPA both change the resource requests of pods in response to changing application resource requirements, there are several key differences.

In the past year alone, we’ve seen just how much a single outage can disrupt and how much stronger teams become when they learn from it. From the July 16, 2024 incident to the widespread June 2025 outage, it’s clear that incidents are inevitable. The question is: how do you transform each disruption into an opportunity to improve your processes for the next one?
