When your system shows a "no healthy upstream" error, it usually means your load balancer can't connect to any of your backend servers. Let's get straight to fixing this problem.

Our production services run on a Linux machine using Docker Compose, keeping our infrastructure simple and manageable. Docker Compose allows us to easily define and manage multi-container applications, providing a straightforward way to orchestrate services, which helps reduce complexity in our infrastructure. Recently, we decided to switch to SigNoz to gain more flexibility and control over our observability stack. Following the SigNoz setup guide, we used logspout to collect and forward logs.

As your IT environment scales, a proactive approach to monitoring becomes increasingly critical. If your infrastructure environment contains multiple service dependencies, disparate systems, or a busy CI/CD application delivery pipeline, overlooked anomalies can result in a domino effect that leads to unplanned downtime and an adverse impact on users.

AWS Lambda supports nearly any programming language by enabling developers to run serverless functions with either supported or custom runtimes. Once a runtime is deprecated, however, AWS will set dates for when you can no longer create or update functions using that runtime. You will then need to decide what course of action to take to ensure your Lambda functions continue running as expected.

Golden Signals—latency, traffic, error rate, and saturation—help SRE teams monitor system health and avoid costly performance issues.

Learn how the OpenTelemetry Operator makes monitoring Kubernetes easier, so you can focus on what matters—keeping your apps running smoothly!

As businesses migrate to the cloud, monitoring these environments becomes critically important. Digital Ocean is a popular developer choice due to its simplicity and scalability. However, effectively monitoring resources and applications within Digital Ocean can pose unique challenges. Hosted Graphite and Telegraf provide robust solutions for these challenges, allowing users to visualize data, track system metrics in real-time, and troubleshoot issues quickly.

We’ve all been hearing about Amazon Bedrock – and the exclusive few who could access the full scope of AWS’ new product. But what exactly is AWS Bedrock? What can it help you accomplish? And, most importantly, when can you get full access to it? Learn all you need to know about AWS’ new tool from our cloud experts.

Every day, telemetry data is emitted, processed, and then either stored or deleted from services. Unfortunately, understanding and then optimizing the telemetry data can be difficult. These difficulties lead to higher MTTR/D, burnout, and unwanted overage bills.

A modern IT infrastructure has many layers—or stacks as we call it—that, together, are critical to running an organization. In this blog series, we’ll attend to each stack in turn, talk about why they matter, and how OpManager Plus is adept at providing visibility into each of them. Let’s start off with the first part, where we dive into the world of application performance management (APM) and understand its indispensable role in ensuring seamless IT operations.
