Tink vs vnstat
vnstat is a Linux console traffic monitor with a daemon, historical rx/tx totals, and optional vnstati graphs. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
vnstat remembers the NIC. Tink answers “why is this VPS sick?”
Accidental sysadmins land on vnstat because vnstat -mneeds no dashboard and the daemon keeps running after logout. Then disk is at 91%, nginx dies, and last month's rx/tx table does not say what to run. A filling /var is a Tink warning; it is not a vnstat daily total.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep using vnstat if you already want historical bandwidth totals on an SSH session. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | vnstat |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | apt/yum install vnstat, start vnstatd, wait for /var/lib/vnstat, then vnstat -i eth0 |
| What you get | Working monitoring, diagnosis, and approved fixes | Hourly/daily/monthly rx/tx totals, vnstat -l live, and optional vnstati PNGs |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Open source. You still pay the person who reads last month's bill after the outage |
| Hidden costs | None — fully managed | Which interface to log, database rotation, and no pager unless you wrap vnstat yourself |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Kernel interface counters in a local database. vnstat does not parse auth.log or propose a command |
| Configuration | None after install — heuristics and AI | vnstat.conf, Interface, DatabaseDir, and whether vnstatd survived the last reboot |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read rx/tx/estimated from vnstat -d yourself |
| Fix execution | Proposes and executes approved commands with an audit trail | Monitoring only — vnstat cannot stop the flood, restart nginx, or rotate a cert |
| Alerting | Built-in across 8 channels | None by default — vnstat is a history database; paging is extra |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Traffic totals only — vnstat does not forecast fill time or a quiet NIC going bad later |
| SSH brute-force detection | Built-in — parses auth.log every scan | Not included — vnstat does not read host auth.log or journald |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | If the host is down you cannot query vnstatd either |
| Public status page | Shareable URL with 90-day history | Not included — vnstati is a PNG of one NIC, not a customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a monthly rx/tx table is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire something else into PagerDuty |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | SSH + vnstat -m. No mechanic you text when /var filled |
| Learning curve | None — works after install | Low to launch; higher to map last month's 400 GB to the process that filled the disk |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want historical NIC totals and will still SSH in when the box is sick |
When vnstat is the right choice
Keep using vnstat when you already want that exact job:
- Historical NIC totals — you need hourly/daily/monthly rx/tx without sitting in a live TUI.
- Interface-oriented — iftop shows sockets; nethogs groups PIDs; nload graphs live; vnstat keeps the bill.
- No extra service — a package and vnstatd on the box, not a hub, SaaS, or Telegram bot.
- No conversation layer wanted — some operators prefer a traffic database and will never use a mechanic.
The real cost of “just run vnstat”
The package is easy to install. A working ops loop for five Linux boxes is not:
- A complete monthly table still means you SSH into the host and change the box by hand when it gets sick
- Host fill, nginx, certs, and SSH brute-force never appear unless you built extra checks
- A filling /var is a Tink disk warning on every scan — vnstat stays an rx/tx counter until you are looking
- A single VPS with nobody logged in still needs a mechanic, not another traffic database
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens vnstat after the outage, and every scan includes a diagnosis a quiet traffic log will not type.
No SSH homework. No silent host. One command install.
