Skills logging (robot)

This modded version of the JiboOS includes a tiny “always works” logging stack for the robot’s old BusyBox + Python 2.7 environment:

• UDP log daemon: receives log messages and appends to a file
• Web log panel: lets you watch the same logfile live in a browser
• Node helper: a tiny client so JS skills can log without pain

Default logfile:

• /tmp/jibo-skills.log

Default ports:

• log daemon UDP: 15140
• web panel HTTP: 15150

1) Start services on the robot - if you used the installer they should be enabled automatically

Log daemon (required)

Init.d:

• /etc/init.d/jibo-skills-logd start
• /etc/init.d/jibo-skills-logd status

Web panel (optional)

Init.d:

• /etc/init.d/jibo-skills-logpanel start
• /etc/init.d/jibo-skills-logpanel status

Open in a browser:

• http://<robot-ip>:15150/

2) Send logs from programs

Node.js (skills)

Use the helper:

• const rlog = require('/opt/jibo/Jibo/Skills/@be/be/be/robot-logger');

API:

• rlog.info(tag, msg, data)
• rlog.warn(tag, msg, data)
• rlog.error(tag, msg, data)
• rlog.debug(tag, msg, data)
• rlog.raw(line) (sends a plain text line)

Examples:

• rlog.info('menu', 'opened main menu')
• rlog.error('radio', 'failed to tune', { station: freq, err: String(e) })

One-liner test:

• node -e "require('/opt/jibo/Jibo/Skills/@be/be/be/robot-logger').info('node-test','hello testajhdgjhasgjd',{x:1})"

Python 2.7

Send a JSON log packet via UDP:

• could be broken atm idk
• python -c 'import socket, time; s=socket.socket(socket.AF_INET,socket.SOCK_DGRAM); s.sendto("{\\\"tag\\\":\\\"py-test\\\",\\\"level\\\":\\\"info\\\",\\\"msg\\\":\\\"hello\\\",\\\"data\\\":{\\\"t\\\":%d}}"%int(time.time()),("127.0.0.1",15140))'

Shell

This bypasses UDP and just appends to the logfile (still useful to verify the panel is tailing):

• echo "RAW $(date) hello" >> /tmp/jibo-skills.log

3) View logs

• tail -f /tmp/jibo-skills.log

4) Configuration (env vars)

Log daemon:

• JIBO_LOGD_HOST (default 127.0.0.1)
• JIBO_LOGD_PORT (default 15140)
• JIBO_LOGD_FILE (default /tmp/jibo-skills.log)

Web panel:

• JIBO_LOGPANEL_BIND (default 0.0.0.0)
• JIBO_LOGPANEL_PORT (default 15150)

Node client:

• JIBO_LOGD_HOST / JIBO_LOGD_PORT

Notes

• If the web panel shows (polling), thats ok it means the browser doesn’t support SSE and it’s using /tail polling instead.
• If the panel is blank, confirm /tail works:
  • wget -qO- "http://127.0.0.1:15150/tail?pos=0&max=5000"
