Tink vs ntopng
ntopng is a network traffic analysis console that classifies flows, hosts, and protocols. It is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
ntopng shows the wire. Tink answers “why is this VPS sick?”
Accidental sysadmins land on ntopng because a web UI of hosts and nDPI protocols looks like monitoring. Then disk is at 91%, nginx dies, and last hour's flow table does not say what to run. A filling /var is a Tink warning; it is not an ntopng conversation.
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 ntopng if you already want packet and flow visibility. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | ntopng |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Install ntopng, pick a capture interface, often Redis, then open the web UI |
| What you get | Working monitoring, diagnosis, and approved fixes | Live flows, hosts, nDPI protocols, and charts — still no command to run when /var fills |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Community is free; Enterprise adds extras. You still pay the person who reads the flow table after the outage |
| Hidden costs | None — fully managed | Packet capture, Redis, disk for ntopng history, and a NIC that can keep up with the mirror |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Packets and NetFlow. ntopng does not parse auth.log or propose a command |
| Configuration | None after install — heuristics and AI | Interface, nDPI, Redis, users, and whether the capture NIC still sees the traffic |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — you read flows and protocol pies yourself |
| Fix execution | Proposes and executes approved commands with an audit trail | Monitoring only — ntopng cannot restart nginx, free disk, or rotate a cert |
| Alerting | Built-in across 8 channels | Optional thresholds in ntopng — host disk, TLS expiry, and SSH brute-force are extra |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Traffic charts only — ntopng does not forecast a filling /var |
| SSH brute-force detection | Built-in — parses auth.log every scan | Not included — a flow to port 22 is not an auth.log failure count |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | If the host is down, the ntopng UI is down with it unless you run it elsewhere |
| Public status page | Shareable URL with 90-day history | Not included — ntopng is an operator console, not a customer status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included — a flow 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 | Browser + ntopng. No mechanic you text when nginx died |
| Learning curve | None — works after install | Low for a demo; higher to keep capture, Redis, and nDPI honest on a busy NIC |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Operators who already want flow/DPI visibility and will still SSH in when the box is sick |
When ntopng is the right choice
Keep using ntopng when you already want that exact job:
- Flow and DPI visibility — you need hosts, conversations, and nDPI protocols, not a mechanic.
- Packet or NetFlow capture — iftop is a TUI; ntopng is a long-running traffic console.
- You already run the stack — capture NIC, Redis, and a browser you will keep open.
- No conversation layer wanted — some operators prefer a flow table and will never use a mechanic.
The real cost of “just run ntopng”
The Community package is easy to try. A working ops loop for five Linux boxes is not:
- A complete flow 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 — ntopng stays a traffic console until you are looking
- A single VPS with nobody logged in still needs a mechanic, not another protocol pie
For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineer who opens ntopng after the outage, and every scan includes a diagnosis a quiet flow table will not type.
No packet homework. No silent host. One command install.
