CMDBsyncer
CMDBsyncer is a rule-based, modular synchronization hub for host and configuration data. It connects your source systems — CMDBs, asset management tools, APIs, CSV files — with your target systems like Checkmk, Netbox, or I-Doit, and keeps them in sync automatically.
Every connection to an external system is configured through an Account. Rules control what gets synchronized, how attributes are transformed, and which hosts are included.
Key Features
- Web Interface with login, 2FA, and user management — all configuration after installation is done in the UI
- Rule Engine to control synchronization based on host attributes, with rewrite, filter, and condition support
- Jinja support throughout rules and configuration fields
- Built-in CMDB mode for managing objects, hosts, and templates directly in CMDBsyncer
- Plugin API to integrate custom data sources with minimal code
- Cron management to schedule sync jobs from the UI
- REST API for external automation
- Ansible support as a dynamic inventory source
- Encryption of stored credentials
- Debug tooling via CLI and web-based debug views
- Monitoring integration via Checkmk Exchange check
How it Works
CMDBsyncer imports hosts and attributes from one or more sources, processes them through the rules engine, and exports the result to the configured targets. Sources and targets can overlap — a system like Checkmk or Netbox can be both.
