dsmview

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

Installation

macOS (Homebrew)

brew tap janvete/tools https://git.janvete.com/seth/homebrew-tools.git
brew install dsmview

Debian / Ubuntu (APT)

echo "deb [trusted=yes] https://git.janvete.com/seth/apt/raw/branch/main ./" | sudo tee /etc/apt/sources.list.d/janvete.list
sudo apt update
sudo apt install dsmview

From source

git clone ssh://git@git-ssh.janvete.com:554/seth/dsmview.git
cd dsmview
pip install .

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, services summary and disk health.
• F2 Logs — live tail of system, auth and package logs (including Active Backup) with severity filters and text search.
• F3 Services — systemctl service list with up/down status and start/stop/restart actions.

r            refresh now
q            quit
