# Health Monitoring for Self-Hosted Instances
This PR implements basic health monitoring for self-hosted instances in
the admin panel.
## Service Status Checks
We're adding real-time health checks for:
- Redis Connection
- Database Connection
- Worker Status
- Message Sync Status
## Existing Functionality
We already have message sync and captcha counters that store aggregated
metrics in cache within a configurable time window (default: 5 minutes).
## New Endpoints
1. `/healthz` - Basic server health check for Kubernetes pod monitoring
2. `/healthz/{serviceName}` - Individual service health checks (returns
200 if healthy)
3. `/metricsz/{metricName}` - Time-windowed metrics (message sync,
captcha)
4. GraphQL resolver in admin panel for UI consumption
All endpoints use the same underlying service, with different
presentation layers for infrastructure and UI needs.

# Introduction
Avoid having multiple `isDefined` definition across our pacakges
Also avoid importing `isDefined` from `twenty-ui` which exposes a huge
barrel for a such little util function
## In a nutshell
Removed own `isDefined.ts` definition from `twenty-ui` `twenty-front`
and `twenty-server` to move it to `twenty-shared`.
Updated imports for each packages, and added explicit dependencies to
`twenty-shared` if not already in place
