v0.5.46

Polling Profiles, ping min/max RTT, full streaming conversion, bug fixes

Added

• Polling Profiles (public/index.html, public/app.js, src/settings.js) — Settings → Poll Intervals now shows five named preset buttons: Fast, Faster, Standard, Slow, and Slower, plus a Custom pill that activates when you drag any slider. A Save Custom Profile button persists your current slider values as a reusable template. The Custom profile survives settings saves and is restored on page load. Standard is the recommended baseline for most routers. Closes issue #52
• Ping card min/max RTT (src/collectors/ping.js, public/index.html, public/app.js) — the ping stat row now shows four fields: RTT · min · max · loss. Min and max are sourced from the RouterOS min-rtt/max-rtt session counters via the proplist parameter. Values colour-code with the same thresholds as RTT. Present on initial page load via ping:history
• API Diagnostics dashboard card (public/js/dashboard-grid.js, public/index.html, public/app.js, src/index.js) — a hidden-by-default card showing live stream counts and a per-collector breakdown of active API streams. Activates only while visible; 2 s refresh via dashcard:focus/dashcard:blur events
• Settings banner reserved space (public/index.html) — the Save status banner now uses visibility instead of display so its space is permanently reserved; clicking Save no longer causes layout shifts

Changed

• Full =interval=N streaming conversion — four remaining polling collectors replaced timer-based setInterval + ros.write() with router-pushed streams; each stream suspends when its page/card is not visible and resumes on focus:
  • src/collectors/vpn.js — WireGuard peer counter stream (/interface/wireguard/peers/print =interval=N)
  • src/collectors/firewall.js — four per-table counter streams (filter, nat, mangle, raw)
  • src/collectors/wireless.js — wifi, wireless, and CAPsMAN registration streams
  • src/collectors/dhcpNetworks.js — four streams (networks, leases, pools, addresses)
• Connections collector idle-gated (src/index.js) — removed page-gate; connections stream runs whenever any browser client is connected, matching the behaviour of all other streaming collectors
• Page-aware stream lifecycle (src/index.js, src/collectors/vpn.js, src/collectors/wireless.js) — _updateVpnStreams() and _updateWirelessStreams() helpers wire page and dashboard card room events to suspend()/resume() so RouterOS serves counter streams only while relevant UI is visible
• Standard polling profile — default intervals aligned to optimised baseline: System 2 s, Connections 3 s, Top Talkers 3 s, Interface Rates 1 s, Bandwidth 3 s, VPN 5 s, Firewall 5 s, Ping 5 s, Wireless 30 s, Interface Metadata 60 s, DHCP Networks ~5 min
• Settings slider ranges (public/app.js, src/settings.js, src/index.js) — eight 30 s-cap sliders changed from 500 ms–30 s to 1 s–30 s; DHCP Networks lower bound raised to 10 s; Ping upper bound raised to 30 s; Wireless upper bound raised to 600 s

Fixed

• WireGuard dashboard card going stale (src/collectors/vpn.js) — _emit() and _startHeartbeat() passed the already-prefixed room name (router-<rid>-dash-card-vpn) to routerIo.to(), which auto-prepends router-<rid>-, producing a double-prefixed room no client ever joins. Fixed by passing bare names (page-vpn, dash-card-vpn)
• Connections stale after poll interval change (src/collectors/connections.js) — _restartStream() now clears _restarting (unblocks _startStream() if an error-recovery timer was in flight), resets _rowsPrev/_partialStreak (prevents first batch being misclassified as partial), and re-arms the watchdog with the current pollMs (old watchdog kept original thresholds after a slow→fast change)
• Stale counter poll method names (src/index.js) — pollFirewall and pollVpn live-apply blocks referenced methods from the pre-streaming era; renamed to match current _stopCounterStreams/_startCounterStreams

Performance

• Firewall initial load proplist (src/collectors/firewall.js) — _loadInitial() now requests only the 11 fields used by _processRule() instead of all 20+ per rule, reducing response size on every Firewall page open
• Routing heartbeat idle guard (src/collectors/routing.js) — heartbeat returns immediately when page-routing room is empty, skipping route/BGP array rebuilds when nobody is watching
• VPN emit scoped to rooms (src/collectors/vpn.js) — heartbeat and _emit() now use io.to('page-vpn').to('dash-card-vpn') instead of io.emit() (was broadcasting to all connected clients every 60 s)
• Connections fallback poll removed (src/collectors/connections.js) — ~40 lines of dead code (_startPollFallback, _runFallbackTick, etc.) removed; watchdog is the sole stream-recovery mechanism
