As the growth lead of an open-source APM tool, I keep interacting with developers from companies of all shapes and sizes. I recently talked with a developer from a fintech startup in India. The startup provides a payment processing platform that enables businesses to accept payments from customers worldwide. For them, monitoring is critical, but the dev shared how limited they were when exploring an APM tool for their application. The reason? Reserve Bank of India.

Our latest release of eG Enterprise, version 7.2 is accompanied by significant enhancements and new features for our popular eG Enterprise mobile app for iOS and Android. These apps allow administrators to access the eG Enterprise administrator console on the go and receive meaningful alerts and push notifications with click throughs to deep diagnosis rather than dumb text messages.

Metrics, Logs and Traces are often referred to as The Three Pillars of “Observability“. The term observability has been used in control theory to refer to how the state of a system can be inferred from the system’s external outputs. Applied to IT, observability is how the current state of an application can be assessed based on the data it generates. Applications and the IT components they use provide outputs in the form of metrics, events, logs and traces (MELT).

Nodejs is a popular Javascript runtime environment that executes Javascript code outside of a web browser. Express is the most popular web frameworks that sits on top of Nodejs and adds functionalities like middleware, routing, etc. to Nodejs. You can monitor your express application using OpenTelemetry and a tracing backend of your choice.

OpenTelemetry can auto-instrument many common modules for a Javascript application. The telemetry data captured can then be sent to SigNoz for analysis and visualization. OpenTelemetry is a set of tools, APIs, and SDKs used to instrument applications to create and manage telemetry data(Logs, metrics, and traces). For any distributed system based on microservice architecture, it's an operational challenge to solve performance issues quickly.
