VRSystemController

VR System Controller Front end UI

Major sections are represented along the top ... Home ... Apps ... RFID ... Network ... System ...

---

Home

Display dashboard page. Machine-specific dashboard pages (include machine-specific.js? or separate in gulp somehow)

• Editable on device?
• Should include any real-time or interactive elements here, and try to keep inner pages static (i.e. no polling or websockets on other tabs, only home tab)

RFID Terminal

• Allow Telnet API commands here? Similar to old vrreader-config (python) RFID terminal interface

I/O

More detailed than the dashboard page. ALL sensors should be reported here, with real-time updating (poll/ws)

• Inputs
• Outputs
• ADC
• Battery
• GPS
• CAN Bus / VRProto devices
• temperature sensors

SSH console

• https://github.com/chjj/term.js
• https://github.com/chjj/tty.js

File browser

• for file upload download to SD card

---

Apps

Run client-uploaded applications. Similar to Impinj support for client bundles of python scripting. We would probably support nodejs as well. Target apps: Encoder app (Thomas's scanner to tag encoding project), Super-Triggermode apps, LLRP app!!!

May want to look into container support for hard limits on cpu, memory, disk, network.

Add ability to write applications on the device itself (!!!) ​https://aws.amazon.com/cloud9/

Status

• show running apps (client-side apps)

App: First

• The first app, some logs, start stop? ...
• start on startup
• delete app

New App

• Figure out a UI for adding stuff
• upload app bundle

---

RFID

name: RFID Service? what to do about multiple readers at the same time ? UHF / HF / LF

RFID Status

• current tagtable? rfid terminal?
• model, serial, etc.

---

Network

Pretty much done with this section...

Status

Show current status, similar to ifconfig? but flashy? Pull from /api/1/net/devices

---

System

Status

/api/1/sys/core

• Hostname
• CPU Load (aka load average, available through /proc/loadavg, already exists, but we should probably use the sysinfo() call) https://man7.org/linux/man-pages/man2/sysinfo.2.html
• Memory
• total / free / buffers / cached (through sysinfo() syscall)
• Uptime (seconds)
• really, everything in sysinfo(), didn't know about that call before today!

/api/1/sys/sensors (or move to IO section)

• temperature / sensors / inputs / outputs?
• GPS most recent location??? num satellites / rssi? speed / HDOP information (maybe we can copy gps-vr.c from the rfid service)
• battery
• don't conflict too much with the RFID service… these are things that should be available from the linux kernel side only (battery slight exception)

Storage

• Disk example:

root@vr-13e781:~# df -kP
Filesystem     1024-blocks   Used Available Capacity Mounted on
rootfs              223408 153372     70036      69% /
ubi0:rootfs         223408 153372     70036      69% /
devtmpfs            126532      0    126532       0% /dev
tmpfs               126640    528    126112       1% /run
tmpfs               126640    416    126224       1% /var/volatil

• • may want to parse this into JSON instead of leaving to the frontend to deal with? :-P
• SD card information ???
• UBIFS pre-fail counters

Processes

• running processes / top (just dump top -b -n 1 for now? parse ps into JSON?)

Logs

• tail of /var/log/messages (or whole file?)
• logrotate configuration / viewing?
• log purging?

Services

• allow disable / restart of some system services
• disable openvpn
• 'monit status' output (to JSON?)
• cron ?
• reboot the whole device

Software tab

name: maybe Versions? Updates? instead

• Image information (danny / dora / dizzy?)
• Version numbers of processes
  • RFID service + build
• /etc/venture-build-info (prefirstrun and firstrun information)
• timestamp of /var/lib/opkg/all (last opkg upgrade timestamp)

• Maybe here put some opkg update / upgrade buttons???
• Or an Install X opkg package… ???

VRPackager

or other name? VR Enterprise software connection???

• dump vrpackager.db
• load up vrpackage to run
• see current agent status (agent in vr-system-controller?)

Time

• Current Date Time
• Time zone selection
• NTP server information
• sync now (run ntpdate -u)

REBOOT

• boom!
