How Airbnb Built a High-Volume Metrics Pipeline with OpenTelemetry and vmagent

Learn how Airbnb rebuilt its observability pipeline with OpenTelemetry and vmagent to handle over 100 million samples per second, reduce cost by 10x, and simplify high-scale metrics aggregation.

Don’t default to microservices: You’ll thank us later!

We believe microservices shouldn’t be the default and that companies should start with monoliths until reality actually demands they scale and shift from one node to a cluster of nodes. As a result, we offer clustering on an open source basis because we want to support realistic growth. Read on for details!

Prometheus Monitoring: Instant Queries and Range Queries Explained

When evaluating, instant vectors provide current snapshots, while range vectors give you multiple values over a period of time. But how do they work?

Prometheus Metrics Explained: Counters, Gauges, Histograms & Summaries

Metrics come in different types: counters that only increase, gauges that fluctuate, histograms that show value distributions, and summaries that pre-calculate statistics.

OpenTelemetry, Prometheus, and More: Which Is Better for Metrics Collection and Propagation?

OpenTelemetry, Prometheus 2.x, Prometheus 3.x, and vmagent are put together for comparison in scraping and pushing data to remote storage.

How vmagent Collects and Ships Metrics Fast with Aggregation, Deduplication, and More

VictoriaMetrics agent, or vmagent, is a lightweight tool designed to gather metrics from a number of different sources. Once it pulls in all those metrics, vmagent lets you ‘design’ them (through ‘relabeling’) or filter them down (doing things like reducing cardinality, stream aggregation, deduplication, and so on) before shipping them off to wherever you want to store them.
