Fixes three critical issues affecting agent-based SNMP polling:
1. MikroTik gauge sensors incorrectly showing 10x values (223°C instead of 22.3°C)
- Root cause: get_int_value() rejected zero values, causing mtxrGaugeUnit
to be treated as nil and bypassing divisor logic
- Fixed: Accept zero values and apply correct divisor=10 for temp/voltage/current/power
2. Empty SNMP community strings sent to agents causing authentication failures
- Root cause: Devices with source="device" but null community weren't falling
back to organization/site inheritance
- Fixed: Enhanced resolve_snmp_community() to fall back to inheritance chain
even when source="device" but community is empty
3. Continuous MikroTik API commands sent every 60s instead of once per 24h
- Root cause: MikroTik jobs built on every poll cycle, not just discovery
- Fixed: Only build MikroTik jobs during discovery phase
Migrations update existing data to fix incorrect divisor values and community
source tracking. Added comprehensive debug logging to diagnose future issues.
- Load available firmware in DeviceLive.Show
- Add firmware_update_available? and format_date helpers
- Display blue indicator banner when newer firmware available
- Show current vs latest version with release date
- Add download link and release notes link
- Support MikroTik initially, extensible to other vendors
Phase 6 (final) of firmware tracking complete. All phases implemented:
✅ Database schema (firmware_releases, device_firmware_history)
✅ Version comparison logic (VersionComparator)
✅ RSS fetching worker (daily Oban cron)
✅ Firmware context with logging and PubSub
✅ Version change detection in Discovery
✅ LiveView UI indicators
- Created new on_mount hook :load_default_organization that automatically loads user's first organization
- Moved sites and devices routes to root path (/ sites, /devices) instead of /orgs/:org_slug
- Updated all navigation links and route references throughout the app
- Dashboard, alerts, and agents still use org-specific routes (/orgs/:org_slug)
- Users can still switch organizations via org selector for other pages
Updated all references to use the more technically accurate term 'ICMP Latency'
instead of 'Ping Latency' in:
- Graph titles and labels
- HTML comments
- Test assertions
- Added comprehensive tests for GraphLive.Show to ensure:
* Page renders with correct assigns
* Uses @current_organization (not @organization)
* Latency, processor, memory, and traffic graphs work
* Time range selection works correctly
* All required assigns are present
- Reordered device show page so Overall Traffic appears above Ping Latency
- Add Monitoring.get_latency_data/2 to query successful checks with response times
- Support 'latency' sensor type in GraphLive.Show with configurable time ranges
- Add latency chart to device show page alongside other metric charts
- Add comprehensive tests for get_latency_data/2 (limit, since, failed checks)
- All 813 tests passing with no Credo warnings
