Línea de trabajo

Comienza con el flujo de filtrado de visualización del lector de logs y reproduce el problema en Nextcloud 34.0.4 usando los niveles warning, error y fatal. Compara la carga filtrada inicial con el filtrado después de una carga sin filtrar, e investiga la ruta de actualización automática. Se considera terminado cuando los logs filtrados se cargan en aproximadamente un segundo sin un pico notable de CPU y la actualización automática vuelve a funcionar.

Steps to reproduce
  1. Use Nextcloud 34.0.4
  2. Go to log reader in admin settings
  3. Set "Filter logging levels" to only display warning, error, fatal (backend log is set to the same settings by default)
  4. refresh the reader
  5. loads for more than 10 seconds

When the filtering is applied after initial load (without any filtering) the filtering happens instantly.
Before we used Nextcloud 32.0.8 - the problem did not exist there.

Expected behaviour
  • Logs typically load within one second
  • No notable CPU spike
  • Logs refresh automatically
Actual behaviour
  • Logs take upwards of 10 seconds to load
  • Extreme CPU usage (in kubernetes from 0.1 CPU to 3.0 CPU)
  • The automatic refresh does not work anymore
