Instances
What is an Instance?
An instance is a running UMH Core container - a single Docker container that hosts your entire Unified Namespace. Each instance is identified by its location path (like enterprise.site.area.line) which determines where data is organized in your industrial data infrastructure.
Instance Overview Page

The instance overview shows all your UMH instances at a glance:
Instance Name: Your chosen identifier for the instance
Type:
Core: Single container deployment (UMH Core)
Classic: Kubernetes-based deployment (legacy)
Version: Container version identifier (e.g.,
9e22396)Data Flows: Number of configured bridges and stand-alone flows
Topics: Total data points in your Unified Namespace
Latency: Network response time in milliseconds
Throughput: Messages per second flowing through the system
Status indicators:
Green dot: Instance is online and reachable
Gray dot: Instance is offline or unreachable
Quick actions: Click the context menu (⋮) on any instance for:

Instance Details Page

The instance details page provides comprehensive monitoring and management:
Agent Panel
Name: Instance identifier (e.g.,
sk-core-hetzner)Location path: Your organizational structure
Level 0: Enterprise (required)
Level 1-4: Site, Area, Line, etc. (optional)
Latency: Connection health indicator (N/A when healthy)
Logs button: Access S6 system logs for diagnostics
Container Panel
Real-time resource monitoring:
CPU: Usage percentage of available cores
Memory: Usage of available RAM (GiB)
Disk: Storage usage (GiB)
Architecture: System architecture (e.g.,
amd64)Hardware ID: Unique container identifier
Data Flows Panel
Bridge and flow status breakdown based on state machines:
Active: Currently processing data (messages flowing)
Neutral: Includes:
idle: Healthy but no data for 30+ secondsstopped: Intentionally disabledstarting: Initialization in progressVarious transition states
Example states:
starting_dfc (port is open): Connection verified, waiting for Benthos initializationstarting: stopping: stopping: Complex state transition in progress
Bridges count: Total configured with active/neutral breakdown
Redpanda Panel
The message broker powering your Unified Namespace:
Incoming Throughput: Data rate into the broker (KiB/s)
Outgoing Throughput: Data rate from the broker (KiB/s)
Logs/Metrics buttons: Direct access to Redpanda diagnostics
Topic Browser Panel
Topics count: Total number of data topics
Quick access to the Topic Browser for data exploration
Release Panel
Version information for support and updates:
Version: Full semantic version (e.g.,
v0.43.4)Channel: Release channel (
stable,beta, etc.)Software versions: Individual component versions (S6 Overlay, Benthos, Redpanda)
