The Grafana & Friends Madrid meetup is back for a fall session at **[Celonis](https://www.celonis.com/)**.

**👉 Here's a sneak peek of the agenda:**

**18:30:** Check-in and welcome 👋

**18:45:** 🎙️ "**Getting Started (and Getting Better) with Alerting in Grafana**", [Antonio Calero](https://www.linkedin.com/in/antonio-cm/) \- Developer Advocate at [Grafana Labs](https://grafana.com)
Alerts are the heartbeat of any monitoring setup; they let you know when something needs your attention before your users do. In this session, we’ll start with the basics of creating alerts in Grafana and walk through how they work, step by step. We’ll also cover some practical tips for those already using alerting, including how to avoid common pitfalls, keep noise under control, and ensure your alerts are actually actionable. Whether you’re new to Grafana or looking to level up your existing alerting setup, you’ll leave with a clearer picture of how to get the most out of alerts.
**19:15:** 🎙️ **“OpenTelemetry developments in Prometheus over the last year”** by [Juraj Michalek](https://www.linkedin.com/in/jurajmichalek/) \- Senior solution architect at [Grafana Labs](https://grafana.com)
Since last year's PromCon, there have been numerous improvements to Prometheus' OpenTelemetry support, more specifically, its OTLP receiver. Among them:

* Converting OpenTelemetry metric metadata to Prometheus equivalent
* Support for keeping identifying attributes in the target_info metric
* Primitive support for ingesting OpenTelemetry delta temporality metrics without converting to cumulative
* Support for ingesting OpenTelemetry metrics without translating metric or attribute names
* Support for translating OpenTelemetry explicit bucket histograms into native histograms with custom buckets
* Promote OpenTelemetry scope metadata to metric labels

**20:00 - 21:00:** Networking, Snacks, and Drinks 🍻🍕

📍**Location:**
