Multiple linked maps
Unlimited maps with map-link nodes that recolour based on the health of the map they point to.
features
Everything CoreBit does
A complete monitoring and documentation platform for on-premise networks — grouped by the job it's doing.
Topology & maps
Infinite canvas
Pan, zoom, snap-to-grid placement, and drag-and-drop from an auto-discovered device list.
Geographic maps
Place devices by latitude/longitude for real-world site layouts.
Rack elevations
TIA-606-B racks rendered as live front/rear elevations with per-slot device status and vitals.
Draw elements
Text labels, boxes, gauges and charts (device vitals, bandwidth, ping, custom metrics) placed anywhere on the canvas.
Global variables & placeholders
Dynamic text that shows device counts, on-duty info and 'at a glance' vitals right on the map.
Device stacking
Group multiple interfaces of one physical device under a parent with aggregated status.
Monitoring & status
Parallel two-lane polling
Healthy and troubled devices are scheduled on separate lanes so one slow device never stalls the rest.
Fail-safe status
Hierarchical checks with ping fallback; a device is only 'offline' when both API/SNMP and ping fail.
Interface monitoring
Link-up/down and speed changes are logged and can notify, inheriting each device's channels.
Service probes
Attach TCP, SSL/TLS-expiry, DNS, HTTP(S) and UDP checks to any device, each with its own thresholds and history.
Calculated metrics & alarms
Combine metrics with a safe formula engine and alert on warning/critical zones — independent of any map.
Status history
A precise per-device timeline built from status events, so outages are auditable after the fact.
Alerting & on-duty
Notification channels
Telegram, Slack, Pushover, e-mail, and generic webhooks (HTTP GET/POST) — e.g. to send SMS.
On-duty scheduling
Shift-based routing with per-group schedules, so alerts reach whoever is actually on call.
Additive group routing
Devices belong to groups; alerts fan out to every matching channel without duplicates.
Templates & muting
Customisable message templates per alert type, plus temporary global or per-user muting.
Source of truth & discovery
Network scanner
Sweep IP ranges with multiple credentials, auto-detect device types, and bulk-create devices.
IPAM
Hierarchical subnet tree with VRF support and automatic IP-to-interface association.
VLAN inventory
Q-BRIDGE-MIB discovery of VLANs and per-interface membership, browsable per device and estate-wide.
MAC address table
On-demand SNMP fetching with caching, search, CSV export and fabric-aware filtering.
MIB library
Vendor-organised MIBs with auto-detection and LibreNMS import for readable OID names.
Living documentation
Discovered data is retained even when it disappears from polling — marked inactive, never silently dropped.
Reports & security testingFree preview
AI-assisted reports
Generate security-scan summaries, work plans and network summaries as saved Markdown reports, tied to a device or the whole estate.
Authorised security testing
Run real, non-destructive scanners (nmap, nuclei, testssl.sh, nikto) against a device you own and turn the findings into a linked report.
Advisory links
Known CVEs are rendered as NVD links alongside any tool-provided references, so remediation starts from the report.
Platform & operations
On-premise, no cloud
Everything runs on your own Linux host. Your topology and credentials never leave your network.
Backup & restore
Manual and scheduled backups with retention, plus selective restore across ten data categories.
User roles
Administrator, SuperUser and Viewer access levels for safe operator and read-only access.
REST API & keys
Scoped API keys (read / readwrite / admin) with a Swagger explorer at /api-docs.
Global search
Jump to any device and highlight it wherever it lives on your maps.
Dark & light themes
A control-room dark theme by default, with a light theme a click away.
integrations
Speaks your network's languages
Point CoreBit at a device and it picks the right method automatically — or add your own metrics by OID or exporter path.
- MikroTik RouterOS API & WinBox — CPU, memory, uptime, firmware, interfaces, IP addresses
- Generic SNMP Device info, CPU, memory, uptime, interfaces, traffic
- Prometheus / node_exporter Recommended for servers — full vitals, traffic, IP & MAC
- Proxmox VE VM placement across a cluster, with dynamic link updates on migration
- VMware vSphere vCenter-to-host monitoring via the plugin system
- HP iLO (Redfish) Out-of-band health for servers and similar hardware
- Ping only Smokeping-style reachability for anything with an address
- Custom metrics Any SNMP OID or exporter metric, with calculated formulas and alarms
