- Add 'Checks' tab link to device navigation
- Display empty state when no checks configured
- Add tests for tab visibility and empty state
- Fix unused variable warnings in monitoring context
- Remove unused CheckResult alias and module attributes
- Add stub for legacy get_latency_data for backward compatibility
Tests: 2 new tests added, all passing
Following TDD: RED-GREEN cycle verified for each feature
Build a rich network topology from SNMP polling data using evidence-based
confidence scoring. LLDP/CDP neighbors, MAC address tables, and ARP data
are combined to infer device links with weighted confidence merging.
- Add DeviceLink and DeviceLinkEvidence schemas for persistent topology
- Implement evidence collectors: LLDP (0.95), CDP (0.95), MAC (0.7), ARP (0.6)
- Add device role inference from sysObjectID/sysDescr patterns
- Hook topology inference into DevicePollerWorker pipeline
- Add stale link cleanup (24h mark stale, 72h delete) via NeighborCleanupWorker
- Update NetworkMapLive with "Added" vs "All Devices" tabs
- Add connected devices section to device detail page
- Add device role selector to device edit form
- Update Cytoscape.js with role-based node shapes/colors and confidence edges
Always broadcast from update_device_status/2 so the device index
LiveView refreshes even when status hasn't changed. Add a 15-second
tick timer to keep "Last Checked" timestamps fresh between polls.
Scope alert PubSub topics to organization for defense-in-depth.
Broadcast org-scoped PubSub events from Devices context mutations
(create, update, delete, status change). Convert DeviceLive.Index
from assigns to streams with flat row items. Subscribe on mount so
the device list updates automatically across browser tabs.
Fixed production bug where visiting the edit page for a device with no
SNMP discovery data would crash with "expected boolean on left-side of
'and', got: nil" error.
The mikrotik_device?/1 function was using && operator which returns nil
when device.snmp_device is nil, instead of returning false. The template
conditional on line 455 requires a proper boolean value.
Changed from:
device.snmp_device && (...)
To:
not is_nil(device.snmp_device) and (...)
This ensures the function always returns a boolean (true/false) instead
of potentially returning nil.
Added regression test to verify the page renders correctly when a device
has no SNMP discovery data yet.
