qNag

A production-minded, FOSS Android Nagios monitoring client inspired by Qnagstamon, built with Kotlin, Jetpack Compose, and Material3.

Features Multi-instance — configure, enable, and monitor multiple Nagios instances simultaneously. ALL-instances dashboard — merged sorted view across all enabled instances. Summary chips and quick filters — tap D/U/C/W/N chips to filter the problem list by state. ACK / Recheck / Remove ACK — with host ACK cascade to related services. Downtime scheduling — service, host, or host + all services; fixed duration. Multi-select actions — bulk ACK, recheck, remove ACK, and downtime. Problem details — full check timing, passive/freshness metadata, open in Nagios link. Reliability Mode — foreground service + Exact Alarm Watchdog + WorkManager fallback. One notification in foreground mode — Reliability Mode normally keeps a single visible qNag status notification in the shade. Advanced notification channels — additional channels exist for compatibility, fallback modes, and optional per-problem notifications. In-app alert sound — independent of Android channel sound settings; can be configured to sound even when the phone is in vibration mode, subject to Android/OEM audio and DND policy. Monitoring Health — live status of all reliability layers with recovery actions. Event Log — in-app log of polling, commands, and reliability events; safe to share. Filters — hide acknowledged, downtime, soft-state, disabled-notification, and regex filters.
