Olá,
Esta manhã, alguns usuários me avisaram que aparentemente nossa instalação do Discourse estava fora do ar, mas quando verifiquei, ela já estava no ar novamente. Houve vários comportamentos “offline” que pude ver em minha pilha de monitoramento, mas quando fui verificar os logs via launcher logs app, parece que eles são exibidos sem data/hora (
) e apenas os mais recentes, presumo, sem distinção real da origem dos logs, pois existem vários componentes que formam uma instalação do Discourse (nginx, redis, psql, etc.).
Existe alguma maneira de ter logs mais precisos ou, melhor ainda, expô-los de alguma forma para que eu possa capturá-los com loki / promtail?
Todos os gráficos são de “últimos 5 dias”, pois adicionei este monitoramento apenas naquela época. Isso é o que posso ver em meu monitoramento:
Uptime do Container:
A partir dos plugins do discourse-prometheus, muitos “buracos”, que suponho serem de quando o Discourse não está respondendo, pois correspondem a quando fui notificado pelos usuários esta manhã:
Zoom nos últimos 6 horas para esclarecer que esta não é uma janela “pequena” e definitivamente não é aceitável pelos usuários, é claro:
