Sentinel

Error tracking and performance monitoring for the Hanzo cloud. Sentinel receives events from your applications, groups them into issues, and tells you which ones are new, regressed, or getting worse.

Sentinel speaks the Sentry wire protocol, so the existing ecosystem of client SDKs reports to it unchanged — a DSN pointing at your Sentinel instance is the only configuration difference. There is no Sentinel-specific SDK to adopt, and none is planned; the protocol is the interface.

Running it

The deployed image is ghcr.io/hanzoai/sentry. Deployment is declared in the universe repository and reconciled by Hanzo CD, like every other service.
