Observability Playgrounds
Remote sandbox environments for learning and experimenting without worrying about setup and cleanup. Run anything on vanilla Linux VMs, get a fresh Docker host or Kubernetes cluster in seconds, publish ports, collaborate via sharing terminal sessions, SSH from the command line, and more.
Official Collection
Playgrounds crafted by iximiuz Labs for efficient hands-on learning and safe experimentation.
Tetragon
A 3-in-1 playground (Kubernetes, Docker, and vanilla Linux hosts) to experiment with Tetragon - an eBFP-powered security observability tool.
Community Collection
Playgrounds contributed by the community members sharing their knowledge and expertise.
USE Practice
Practice Linux USE-method investigations against randomized host-level scenarios. It already has the [use-tool](https://github.com/lpmi-13/use-tool) installed, so you can begin with that, or just run a free-form investigation.
Cloud Tracing Lab
Diagnose realistic distributed tracing scenarios in a preloaded k3s VM, for users to get more familiar with traces in general and jaeger-ui specifically. There's guided investigation through distributed traces, along with identification of slow spans and comparing two traces to identify what changed to make it slow down.
ELK Stack
This is a hands-on ELK (Elasticsearch, Logstash, Kibana) playground enhanced with Docker and Beats to simulate real-world log and observability scenarios. It includes an Elastic Cluster (es-node-01 and es-node-02) for storing and indexing data, a test-node-03 running Docker with Filebeat, Metricbeat, and Heartbeat for log and metric collection, and kibana-node-04 for visualizing everything via Kibana UI—perfect for learning and experimentation.
Vendor Materials
Playgrounds prepared by software vendors to help you learn and experiment with their products and services.
VictoriaMetrics Cluster
A multi-node VictoriaMetrics cluster with vminsert, vmselect, and vmstorage components.
