- Skip HTTP/TCP/DNS checks in Phoenix when device is assigned to agent
- Agents now execute service checks from the device's network location
- Fix cancel button in service check modal (text link instead of button)
- Fix status badge alignment in checks table

send check_jobs protobuf to agents during job dispatch cycle, handle
check_result messages back with state transitions and alert
creation/resolution. auto-assign checks to device's effective agent
token on creation, broadcast check changes via PubSub so connected
agents get immediate updates.
add edit/delete support for service checks on device show page with
form pre-population from existing check config. auto-fill TCP host
from device IP address.
includes validate_check_result/1 for protobuf validation and
list_checks_for_agent/2 for querying agent-assigned service checks.
also fixes pre-existing broken device_type_icon reference in device
index template.

Add CapacityInsightWorker (every 15 min) that generates critical/warning
insights when backhaul utilization exceeds 90%/75% and auto-resolves
when it drops below 70%.
Add capacity and utilization columns to the device ports tab with
set/clear capacity controls. Add organization-level /capacity page
with summary cards and per-site capacity table. Add capacity summary
card to site show page. Add Capacity link to nav menu.
The template accessed if_in_octets/if_out_octets directly on the
Interface struct, but these fields live on InterfaceStat. Access
through interface.latest_stat with nil guard to prevent KeyError
when the association is not loaded.
When the Oban queue backs up, the 60-second uniqueness window expires
and duplicate jobs stack up per device. Switch to period: :infinity so
only one poll/monitor job exists per device at any time. Add replace
option to supersede stale scheduled jobs with updated scheduled_at.
Remove :executing from unique states so self-scheduling works while
the current job runs. Set max_attempts: 1 since retrying stale polls
is pointless.
Also fix all credo --strict issues across the codebase.
Temporarily disable all MikroTik-related UI elements using false guards.
Code is preserved and can be re-enabled by removing the guards.

This commit implements the unified checks architecture that consolidates
SNMP monitoring with HTTP/TCP/DNS checks under a single "check" abstraction,
enabling consistent graphing, alerting, and management across all check types.
Database Changes:
- Add source_type and source_id to checks table for tracking auto-discovered
vs manually created checks
- Add value field to check_results for storing numeric sensor readings
- Maintain backward compatibility with existing check_results data
New SNMP Executors:
- SnmpSensorExecutor: Poll sensor OIDs and return formatted values with
status determination (OK/WARNING/CRITICAL based on limits)
- SnmpInterfaceExecutor: Poll interface stats (bandwidth, packets, errors)
- SnmpProcessorExecutor: Poll CPU/processor usage
- SnmpStorageExecutor: Poll disk/memory usage with percentage calculations
Check Execution Worker:
- CheckExecutorWorker: Unified Oban worker that dispatches to appropriate
executor based on check_type (snmp_sensor, snmp_interface, http, tcp, etc.)
- Self-schedules next execution with distributed polling offsets
- Records results in check_results TimescaleDB hypertable
- Updates check state (OK/WARNING/CRITICAL/UNKNOWN)
Discovery Integration:
- Auto-creates checks during SNMP discovery for sensors, interfaces,
processors, and storage
- Links checks to source entities via source_id for data lookup
- Enables/disables checks based on discovery results
UI Enhancements:
- Checks tab on device detail page with grouped display
- FormComponent for adding manual HTTP/TCP/DNS checks
- Empty state with "Run Discovery" prompt
- Check status badges and last checked times
Graphing:
- Update GraphLive to accept check_id parameter
- Query check_results table for time-series data
- Support all check types (SNMP, HTTP response times, etc.)
Testing:
- Comprehensive test suite for SnmpSensorExecutor (5 tests)
- Test suite for CheckExecutorWorker (7 tests)
- Test coverage for discovery check creation (6 tests)
- Remove deprecated monitoring_test.exs testing old API
Bug Fixes:
- Fix SNMP executors reading credentials from correct Device schema fields
(device.snmp_version instead of device.snmp_device.version)
- Update agent channel test to query MonitoringCheck table directly
Code Quality:
- Extract add_snmp_credentials helper to reduce cyclomatic complexity
- Use map-based lookups for sensor formatting and check type grouping
- Apply pattern matching in dispatcher to reduce complexity
- All credo checks passing with no issues

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
gosnmp returns OIDs with leading dots (e.g., ".1.3.6.1.2.1.1.1.0")
but the Replay adapter did exact-match lookups without the dot.
Walks already normalized both sides, so interfaces worked. GETs
did not, breaking all system OID resolution (sysDescr, sysName, etc).
Show the specific cloud poller name (e.g., dfw, lon) alongside "Cloud"
when a device is assigned to a cloud poller. Displays as "Cloud (dfw)"
instead of just "Cloud" for better visibility of which poller is being used.
When no agent is assigned, continues to show just "Cloud".
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
