The most common Apache ActiveMQ high availability mistake is not a configuration error; it is a false assumption. Teams deploy two broker instances, point clients at both with a comma-separated URL, and label the topology "HA." Then the primary crashes, the secondary does not have the message state, and clients start throwing exceptions while the ops team scrambles.

Sometimes, we need to do some spring cleaning when it comes to our devices, as over time, leftover files can be left on our devices, or junk files could be slowing down our computer and taking up our local storage.

AI has since become an integral part of our lives, whether it’s for work or personal use; we all use AI in some form or another. However, deciding which is the best AI depends on how you want to use it. Whether it's for general questions, coding, deep research, or image creation, we’re lucky enough that there is an AI model available to help you out.

Health check endpoints generate thousands of identical, useless spans per day. Here are two production-ready approaches to filter them from your Python OTel traces — and the correctness trap most implementations miss. Prathamesh works as an evangelist at Last9, runs SRE stories - where SRE and DevOps folks share their stories, and maintains o11y.wiki - a glossary of all terms related to observability.

OpenTelemetry's GenAI instrumentation gives you spans and token counts. It does not give you conversations, workflow cost rollups, or prompts visible in your dashboard. last9-genai is an OTel extension that fills those three gaps — without replacing your existing observability stack.

The demands on financial services companies are intensifying rapidly. They must not only deliver seamless system performance but also control costs, secure sensitive data, and maximize the value of their observability investments. To navigate these converging pressures, leaders are evolving their approach to system monitoring and telemetry. The 2026 State of Observability in Financial Services research report reveals a fundamental shift in how organizations manage their digital infrastructure.

We're excited to announce the release of HAProxy Enterprise 3.3, which brings significant advancements to the HAProxy Enterprise WAF and bot management capabilities.

IT operations are in a new era – teams are expected to deliver always-on reliability, absorb constant change, manage runaway telemetry volumes, and still prove business impact. The IDC MarketScape: Worldwide AIOps 2026 Vendor Assessment (doc, March 2026) offers ITOps leaders a valuable lens on the AIOps landscape and the providers shaping what comes next.

Pandemic-era shortages are still fresh in many minds. As consumers, we remember empty shelves and long lines driven by panic buying and stockpiling. In telecom, the story played out differently but with the same root cause: factory shutdowns interrupted chip fabrication just as demand for networking and optical equipment surged.

The OTLPMetricsWriter is a new Icinga 2 feature available since v2.16 that exports check plugin performance data as OpenTelemetry-compliant metrics via the OTLP HTTP protocol. With a single configuration object, it connects Icinga 2 to any OTLP-compatible backend like Prometheus, Grafana Mimir, Datadog, Elasticsearch, VictoriaMetrics, and more.
