CI/CD Observability with OpenTelemetry - A Step by Step Guide

Jun 10, 2025 By Elizabeth Mathew In SigNoz
In the fast-paced world of CI/CD, understanding the performance and behaviour of your pipelines is crucial. GitHub Actions has become a popular choice for automating builds and deployments, but anyone who's debugged a flaky workflow or long-running job knows how challenging it can be to get visibility into what's happening under the hood. We usually rely on build logs, timing data, or guesswork when something goes wrong.

Monitoring Backstage with OpenTelemetry:Closing the observability blind spot

Jun 2, 2025 By Elizabeth Mathew In SigNoz
‘One small step for a man, but a huge leap for developers’ — me, when I realised how to observe my Backstage with OpenTelemetry. Backstage is often the “portal” through which we manage all our other systems, but who watches the watcher? Recently, we gave a KubeCon Talk, highlighting that monitoring Backstage itself is critical. When Backstage isn’t observable, it becomes a blind spot in your infrastructure.

Shedding Light on Kafka's Black Box Problem (with OpenTelemetry)

May 26, 2025 By Elizabeth Mathew In SigNoz
"All language is but a poor translation." — Franz Kafka This quote by Franz Kafka reminds me of the time when I used to look at metrics from “Apache Kafka” topics trying to figure out what was causing the huge lags and manually deleting the messages in certain partitions to get rid of polluted messages. Yep, pretty lost in translation. I wasn’t aware of the power of observability for a Kafka producer-topic-consumer system.

Tracing Funnels - Define funnels between spans | SigNoz Launch Week 4.0 Day 5

May 17, 2025 By SigNoz - Open Source Observability Platform In SigNoz
Build funnels directly on your traces and get instant answers to questions like: What fraction of spans made it from event A to event B? Between which spans are most requests failing? What is the latency between key spans? Traditional observability tools let you inspect traces and spans, but they can’t aggregate or analyze how requests flow across multiple services or stages in your system. In asynchronous, distributed architectures, the root span rarely tells the full story-and there’s no way to measure conversion, drop-off, or latency between arbitrary steps across all traces.
