VictoriaLogs vs Loki, Elasticsearch, OpenSearch, SigNoz and ClickStack on structured log ingestion
We benchmarked structured log ingestion in VictoriaLogs, Loki, Elasticsearch, OpenSearch, SigNoz and ClickStack, and explain the trade-offs behind each result.
Finding Why Payments Fail with VictoriaLogs Drilldown
The VictoriaLogs data source for Grafana now ships with Drilldown, a point-and-click way to explore logs without writing queries. In this post, we use it to investigate failing payments in the OpenTelemetry demo shop, going from a single warning to the release, the log message, and the line of code behind it, all without typing a line of LogsQL.
What Is Observability? It’s More Than Metrics, Logs, and Traces
Observability is a practice, not a product. Learn how metrics, logs, traces, and OpenTelemetry help engineers investigate problems and understand their systems.
The Year-2 Price Cliff: What Your Observability Stack Really Costs Over 3 Years
Why aggressive year-1 discounts in observability often lead to 2–3x renewal bills, plus a simple 3-year TCO framework and five questions to ask before signing.
The Life of a Metric
Follow a single metric through its whole life inside VictoriaMetrics: born as a counter in your process, exported over the wire, given an identity and an inverted-index entry, written through an LSM tree, compressed into columnar blocks on disk, read back by a rate() query, downsampled as it ages, and finally deleted when retention runs out.
Observability's Sixth Sense: Grounding Anomaly Detection in Reality
Learn how VictoriaMetrics combines machine learning, MCP, and natural-language workflows to simplify observability with anomaly detection and reduce operational overhead.
What's new in VictoriaMetrics Anomaly Detection (Q2 2026)
The Q2 2026 vmanomaly update introduces Temporal Envelope, a redesigned UI, faster online-model execution, and an AI-assisted workflow that turns natural-language monitoring goals into tested configurations and alerting rules.
GPU Observability with the OpenLIT Collector and the VictoriaMetrics observability stack
Monitor NVIDIA, AMD, and Intel GPUs with the OpenLIT OpenTelemetry GPU Collector and the VictoriaMetrics stack: eBPF CUDA kernel tracing, OTel hardware semantic conventions, MetricsQL queries, recording rules, and alerts.
Observability for LLM Apps and Agents: OpenLIT SDK + VictoriaMetrics observability stack
See practical examples on monitoring LLM applications and Agents with OpenLIT and VictoriaMetrics observability stack. See real examples of the deployment manifests, alerting rules and Grafana dashboard.
