Why Observability Isn't Just for SREs (and How Devs Can Get Started)

Jul 30, 2025 By Elizabeth Mathew In SigNoz
Almost every other day, when I scroll past r/devops or r/sre, I see a post like this asking how a dev can get started with devops, observability, etc. Sample Reddit thread on how to get started with OTel This blog is an attempt for anyone lost to find their way into observability and a wake-up call for devs to they should think about observability more actively today than ever before. A dev’s observability playbook.

New in OTel: Auto-Instrument Your Apps with the OTel Injector

Jul 29, 2025 By Anjali Udasi In Last9
As distributed systems scale, maintaining manual instrumentation across services quickly becomes unsustainable. The OTel Injector addresses this by automatically attaching OpenTelemetry instrumentation to applications, no code changes needed. This blog covers how the OTel Injector works, how it integrates with Linux environments, and how to set it up for consistent telemetry across your stack.

Why Your Loki Metrics Are Disappearing (And How to Fix It)

Jul 29, 2025 By Faiz Shaikh In Last9
Grafana Loki is up and running, log ingestion looks healthy, and dashboards are rendering without issues. But when you query logs from a few weeks ago, the data's missing. This is a recurring problem for many teams using Loki in production: while the system handles short-term log visibility well, it often lacks the retention guarantees developers expect for historical analysis and incident review.

How Prometheus 3.0 Fixes Resource Attributes for OTel Metrics

Jul 28, 2025 By Anjali Udasi In Last9
When you export OpenTelemetry metrics to Prometheus, resource fields like service.name or deployment.environment don’t show up as metric labels. Prometheus drops them. To use them in queries, you’d have to join with target_info: This makes filtering and grouping more difficult than necessary. Prometheus 3.0 changes that. It supports resource attribute promotion—automatically converting OpenTelemetry resource fields into Prometheus labels.

OTel Weaver: Consistent Observability with Semantic Conventions

Jul 28, 2025 By Anjali Udasi In Last9
Deploying a new service shouldn’t break dashboards. But it happens, usually because metric names or labels aren’t consistent across teams. You end up with traces that don’t link, metrics that don’t align, and queries that take hours to debug, not because the system is complex, but because the telemetry is fragmented. OTel Weaver addresses this by enforcing OpenTelemetry semantic conventions at the source.

How sum_over_time Works in Prometheus

Jul 25, 2025 By Faiz Shaikh In Last9
The sum_over_time() function in Prometheus gives you a way to aggregate counter resets, gauge fluctuations, and histogram samples across specific time windows. Instead of seeing point-in-time values, you get the cumulative total of all data points within your chosen range—useful for calculating totals from rate data, tracking accumulated errors, or understanding resource consumption patterns over custom intervals.

Use Telegraf Without the Prometheus Complexity

Jul 24, 2025 By Anjali Udasi In Last9
Every system needs observability. You need to know what your CPU, memory, disk, and network are doing, and maybe keep an eye on database query latency or Redis connection counts. But setting that up isn’t always simple. You start with a couple of shell scripts. Then come exporters. Then Prometheus. Before long, you’re managing scrape configs, tuning retention, and watching dashboards fail under load after two days of data.

Ship Confluent Cloud Observability in Minutes

Jul 22, 2025 By Anjali Udasi In Last9
You're running Kafka on Confluent Cloud. You care about lag, throughput, retries, and replication. But where do you see those metrics? Confluent gives you metrics, sure, but not all in one place. Some live behind a metrics API, others behind Connect clusters or Schema Registries. You either wire them manually or give up. What if you could stream those metrics to a platform built for high-frequency, high-cardinality time series, and do it in minutes?
