Shows the full UTC timestamp when hovering over the relative 'time ago'
text on the equipment detail page.
Changes:
- Wrapped time_ago display in a span with title attribute
- Title shows full datetime in UTC format
- Added cursor-help class for visual hint that tooltip is available
Users can now see both the easy-to-read relative time ('5m ago') and
the precise UTC timestamp (2026-01-04 19:30:15Z) by hovering.
Added back navigation links at the top of all edit/new pages to
improve UX and make it easier to navigate back to previous pages.
Changes:
- Added back link to equipment edit/new pages
- Edit: goes back to equipment detail page
- New: goes back to equipment list
- Added back link to site edit/new pages
- Edit: goes back to site detail page
- New: goes back to sites list
- Links styled with arrow icon and subtle hover effect
- Added error handling to Counter64 decoder with try/rescue
The back links appear above the page header and provide clear
navigation context for users.
Added a new 'danger' button variant to the button component for
destructive actions like deleting equipment or sites.
Changes:
- Added 'danger' variant to button component (red background/hover)
- Updated equipment delete button to use variant="danger"
- Updated site delete button to use variant="danger"
- Removed custom red color classes in favor of standardized variant
This provides consistent styling for all delete/destructive actions
across the application while maintaining proper button base styles
(padding, rounded corners, shadow, focus ring, etc).
Removed the manual 'Check Now' functionality since polling happens
automatically on a schedule with distributed coordination. Manual
triggers would interfere with the coordinated polling system.
Changes:
- Removed 'Check Now' button from equipment detail page
- Removed trigger_check event handler
- Simplified Discover and Edit buttons to use standard button styling
- Removed custom classes in favor of default button component styling
The equipment is now polled automatically based on its configured
check_interval_seconds, coordinated across all pods.
Some SNMP implementations return 16-byte binaries for Counter64 values
instead of the standard 8 bytes. Updated decoder to:
- Handle 8-byte standard Counter64
- Handle 16-byte values by reading last 8 bytes
- Handle any size > 8 bytes by reading last 8 bytes
- Add debug/warning logging for non-standard sizes
This fixes DBConnection.EncodeError when polling interface statistics
from devices that return non-standard Counter64 encodings.
Prevents duplicate polling when multiple pods are running by using
database-based coordination.
Changes:
- Added last_snmp_poll_at timestamp to equipment table
- Added Equipment.update_snmp_poll_time/1 function
- Updated PollerWorker to check last_snmp_poll_at before polling
- Polls are skipped if equipment was polled within (interval - 5s)
- Updates timestamp before polling (optimistic locking)
This ensures that when K8s scales up/down or pods restart, only one
pod polls each piece of equipment at a time, preventing wasteful
duplicate SNMP queries and database writes.
The 5-second grace period accounts for clock drift and processing delays
between pods.
Improved startup reliability and debugging for SNMP pollers:
- Added try/rescue blocks around monitor and poller startup
- Added logging for successful startup and errors
- Added error logging to PollerWorker's perform_poll
- Added debug logging for successful sensor/interface polls
This will help identify issues when pollers fail to start or
encounter errors during polling, which was causing silent failures
where sensors weren't being collected.
Storage sensors (disk/memory usage) need to fetch two OIDs to calculate
percentages: the 'used' value and the 'size' value. Previously, only the
'used' OID was stored and polled, resulting in meaningless raw values.
Changes:
- Added metadata JSONB field to snmp_sensors table
- Updated Sensor schema to include metadata field
- Updated MikroTik profile to store size_oid in metadata for storage sensors
- Updated PollerWorker to handle percentage calculation sensors:
- poll_simple_sensor: Standard OID fetch with divisor
- poll_percentage_sensor: Fetches both used and size OIDs, calculates percentage
Storage sensors now properly calculate and store percentage values during polling.
NOTE: Existing MikroTik devices need to re-run SNMP discovery to populate
the metadata field for storage sensors.
SNMP Counter64 values (used for interface byte counters) are returned
as 8-byte binary data by SNMPKit and need to be decoded to integers
before database insertion.
Added decode_snmp_value/1 helper that:
- Passes through numeric values unchanged
- Decodes 8-byte binaries as 64-bit unsigned big-endian integers
- Returns nil for unknown formats
Updated both sensor and interface polling to use this decoder,
preventing DBConnection.EncodeError when trying to insert binary
values into integer columns.
Add background workers to regularly poll SNMP sensors and interfaces:
- Create PollerWorker GenServer to poll SNMP devices
- Poll all sensors for temperature, voltage, CPU, memory, etc.
- Poll all interfaces for bandwidth, errors, and discards
- Save time-series data to snmp_sensor_readings and snmp_interface_stats
- Integrate with monitoring supervisor to auto-start pollers
- Use same interval as connectivity checks (minimum 30 seconds)
- Add list_snmp_enabled_equipment function to Equipment context
Pollers start automatically on app boot for all SNMP-enabled equipment
and run independently of connectivity monitoring.

Monitoring Infrastructure:
- lib/towerops/monitoring/ping.ex - OS-agnostic ping functionality that works on macOS, Linux, and Windows
- lib/towerops/monitoring/equipment_monitor.ex - GenServer that monitors individual equipment at configurable intervals
- lib/towerops/monitoring/supervisor.ex - DynamicSupervisor with Registry for managing monitor workers
- lib/towerops/monitoring.ex - Context for creating and querying monitoring checks
Database:
- monitoring_checks table stores historical ping results with status, response time, and timestamps
- Indexed on (equipment_id, checked_at) for efficient querying
Real-Time Updates:
- PubSub broadcasting on equipment:#{id} topic when status changes
- Equipment show page subscribes to updates and refreshes automatically
- Manual "Check Now" button to trigger immediate checks
Application Integration:
- Monitoring.Supervisor added to application supervision tree
- All monitored equipment starts monitoring automatically on app startup
- Recent checks displayed in Equipment show page
How It Works
1. On application start, a monitor GenServer is spawned for each equipment with monitoring_enabled: true
2. Each monitor pings its equipment at the configured interval (default 5 minutes)
3. Results are saved to monitoring_checks table
4. Equipment status is updated if it changes (up ↔ down)
5. Status changes are broadcast via PubSub to all connected LiveViews
6. The Equipment show page updates in real-time when status changes
