Two issues fixed:
1. Cloud pollers (organization_id = nil) were causing access denied errors
when superadmins tried to view them. Now allows access if user is
superadmin and agent is a cloud poller.
2. Ecto.NoResultsError was being raised without required :queryable option,
causing KeyError crash. Now properly raises with queryable parameter.
Error was:
KeyError: key :queryable not found in []
(ecto 3.13.5) lib/ecto/exceptions.ex:203: Ecto.NoResultsError.exception/1
(towerops) lib/towerops_web/live/agent_live/show.ex:16: mount/3
Extracted 5 shared helper functions into ToweropsWeb.AgentLive.Helpers:
- agent_status/1 - Determines online/warning/offline/never status
- status_badge_class/1 - Returns Tailwind CSS classes for status badges
- status_dot_class/1 - Returns CSS classes for animated status dots
- format_last_seen/1 - Formats DateTime as human-readable time ago
- format_uptime/1 - Formats uptime seconds as days/hours/minutes
Removed duplicate code from:
- lib/towerops_web/live/agent_live/index.ex
- lib/towerops_web/live/agent_live/show.ex
Both modules now import the shared helpers, following DRY principle.
This reduces code duplication and makes status formatting consistent
across all agent-related pages.
1. Fixed Docker Compose example to include socket mount
- Added /var/run/docker.sock mount for auto-updates in agent modal
2. Show total equipment count with inheritance
- Display both direct and inherited equipment counts in agents table
- Shows breakdown: 'X total' with 'Y direct · Z inherited' details
3. Add visual status indicators with better CSS
- Added animated pulsing dots for online agents
- Color-coded status dots (green=online, yellow=warning, red=offline)
- Improved status badge styling
4. Create agent detail page with metrics
- New /agents/:id page showing comprehensive agent health
- 4 metric cards: Status, Equipment count, Last seen, Agent info
- Displays agent metadata (hostname, version, uptime)
- Lists all polling targets with assignment source badges
- Shows direct vs inherited equipment assignments
- Clickable agent names in table link to detail page
5. Add health endpoint to Rust agent
- Added /health HTTP endpoint on port 8080
- Returns JSON with agent status, version, uptime, metrics pending
- Uses lightweight tiny_http server
- Non-blocking background thread
- Ready for monitoring/health checks
