Jan Vetesnik b1e0ad0585 v0.2.0: consolidated dashboard, 1s refresh tier, fixed log filter, DSM 7.3+ parsers 
UI
- F1 Dashboard now holds CPU/MEM/storage/network/services/disks in a
  single dense view (was split across F1/F3/F4). F2 Logs stays separate.
- CPU and MEM rendered inline (label + bar + summary on one row) so the
  dashboard fits more on screen.
- DataTables and Services list capped for compactness; services sorted
  with interesting+running first.

Refresh
- Three tiers: fast (1s) for system+network, medium (5s) for storage+
  services, slow (30s) for disks (smartctl is heavy). Each tier runs
  in an exclusive worker group so overlaps are dropped, not queued.

Log filter
- Bindings (a / 1-4) moved from LogsTab container to the App, so they
  fire regardless of focus. Pressing one auto-switches to the logs tab.

Synology DSM 7.3+ compatibility (verified against DS720+ / DSM 7.3.2)
- DSM version read from /etc/VERSION (synoinfo.conf no longer has
  productversion on newer DSM).
- Disks discovered as /dev/sata{N} as well as /dev/sd{a..z} and NVMe;
  smartctl runs with -d sat so SMART data is actually readable.
- SAS-style smartctl output (Vendor:/Product:) parsed as a fallback
  when Device Model: is absent.
- Services collected via plain systemctl list-units, since
  synoservicectl/synosystemctl are gone on recent DSM builds.
- Network primary() picks the interface with the most accumulated
  traffic instead of hard-coded eth0.

Cleanup
- Removed ConfirmDialog and service start/stop/restart actions — the
  app is now truly read-only, matching the stated philosophy and
  eliminating a key conflict with `r`=refresh.

README.md

dsmview

TUI SSH monitor for Synology DSM 7.x — read-only dashboard inspired by btop.

brew tap janvete/tools
brew install dsmview

Usage

dsmview ssh -p334 root@192.168.1.100
dsmview ssh root@192.168.1.100      # default port 22
dsmview ssh nas-home                # alias from ~/.ssh/config
dsmview ssh -i ~/.ssh/id_nas root@IP

Reads ~/.ssh/config (HostName, Port, IdentityFile, ProxyJump). Tries id_ed25519, id_ecdsa, id_rsa, then the SSH agent. Falls back to a password prompt only when no key works.

Read-only philosophy

The application only reads data from the NAS. No agent is installed, no configuration is touched. The single exception is start/stop/restart of a service — and that requires explicit confirmation in the UI.

Tabs

  • F1 Dashboard — CPU history graph, memory, storage pools, network throughput, load average, temperatures.
  • F2 Logs — live tail of /var/log/messages and /var/log/auth.log with severity filters (ALL / ERROR / WARN / SECURITY / INFO).
  • F3 Services — synoservicectl --list table with up/down status and restart/stop/start actions.
  • F4 Disks — per-disk model/size/temp/health from smartctl plus RAID status from /proc/mdstat.

Keys

F1..F4  switch tab
r       refresh now
q       quit

Requirements

  • Python 3.12+
  • Synology DSM 7.x with SSH enabled and a user that can run system commands (typically root or a user in administrators).
