Přidal jsem Health Monitoring do portálu:

Přehled má nové karty: Zdravé služby, Nezdravé služby, Nedostupné služby.
Přehled zobrazuje sekci Služby vyžadující pozornost pro unhealthy a unreachable.
Snapshot /portal/ws/operations teď obsahuje health data a stránka je aktualizuje přes existující realtime vrstvu.
Seznam služeb zobrazuje aktuální health status a poslední kontrolu, včetně řazení Podle zdraví.
Detail služby má sekce Zdraví služby a Historie kontrol s posledními 50 záznamy.
Přidal jsem audit event service.health.view.
Browser title teď používá formát CSBot Services Portal - ..., takže detail služby odpovídá požadavku.
Nepoužil jsem ORM, vše je přes SQLite dotazy.
