Introducing Eventum Hub: Ready-to-Use Data Generators in One Place

Browse, search, and launch synthetic data generators for cloud, network, endpoint, security, and more — all from a single catalog.

We're excited to launch Eventum Hub — a curated catalog of synthetic data generators.

The Problem

You need realistic test data. Maybe you're building a SIEM pipeline, load-testing a log aggregator, training an ML model, or just trying to see if your Kafka consumer handles malformed JSON gracefully. The options are: write a script that outputs {"foo": "bar"} a thousand times, find a public dataset that's close enough, or spend hours crafting realistic samples by hand.

None of these are great.

One Catalog, Every Data Source You Need

Eventum Hub is a growing catalog of generators across categories like Cloud, Endpoint, Network, Security, Web & Access, and Email. Each one produces schema-compliant, statistically realistic events — ECS-compatible JSON with proper field distributions, correlated sessions, and weighted event frequencies based on production traffic patterns.

New generators are added regularly. Browse the full catalog to see what's available.

Browse and Discover

The Hub page features full-text search, category filters, and format filters. Find what you need in seconds:

  • Search by name, description, or event type
  • Filter by category (Cloud, Endpoint, Network, Security, Web & Access, Email)
  • Filter by output format (JSON, ECS)

Each generator has a dedicated detail page with event type tables, realism features, configurable parameters, and sample JSON output with syntax highlighting.

From Zero to Events in 30 Seconds

Every generator page includes a Quick Start section with copy-paste commands. Pick your deployment method:

CLI:

uv tool install eventum-generator
git clone https://github.com/eventum-generator/content-packs.git
cd content-packs
eventum generate \
  --path generators/windows-security/generator.yml \
  --id windows-security \
  --live-mode

Docker:

git clone https://github.com/eventum-generator/content-packs.git
cd content-packs
docker compose up -d

That's it. Realistic Windows Security events (or any other source) streaming to a file (by default).

What Makes the Data Realistic?

These aren't random field generators. Each content pack models real-world behavior:

  • Weighted event distributions — logon events dominate Windows Security logs, not audit policy changes. The generators match production ratios.
  • Correlated sessions — a VPN connection triggers authentication, IP assignment, and eventual disconnection. Events reference the same session IDs, users, and hosts.
  • Realistic field values — IP addresses from proper RFC 1918 ranges, valid UUIDs, plausible usernames, correct event ID codes.
  • Configurable parameters — domain names, IP ranges, hostnames, and fleet sizes are all tunable via CLI flags.

Open and Growing

All content packs are open source on GitHub. New generators are added regularly — and if you don't see the data source you need, contributions are welcome.
