Munin is the classic Debian graphing stack. It polls munin-node, stores RRDs, and draws pretty pictures every five minutes. It is not a mechanic. Tink installs in one command, watches the Linux server, explains what is wrong, and helps you fix it.
Accidental sysadmins often land on Munin because Ubuntu still ships it and every older howto says apt install munin munin-node. When nginx is down, the disk will fill in six days, or SSH is being brute-forced, Munin stays quiet unless you already enabled that plugin, set field.warning, and opened port 4949 to the master.
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 Munin if you live in custom RRD plugins. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | Munin |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — munin master, munin-node on every host, plugin list, CGI/FastCGI graphs, cron |
| What you get | Working monitoring, diagnosis, and approved fixes | Five-minute RRD graphs and optional munin-limits emails |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Free (GPL) — you pay the master host, RRD disk, and the person who debugs plugins |
| Hidden costs | None — fully managed | A graph master, FastCGI, growing RRD files, and plugin version pins |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | munin-node plugins polled by a central master every 5 minutes |
| Configuration | None after install — heuristics and AI | Add nodes in munin.conf, enable plugins, tune warning/critical in plugin config |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | No — a graph and, if you set limits, a threshold mail |
| Fix execution | Proposes and executes approved commands with an audit trail | Monitoring only — you still SSH in |
| Alerting | Built-in across 8 channels | munin-limits to email/Nagios — not a first-class multi-channel product |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | No — a plugin field is ok or crossed |
| SSH brute-force detection | Built-in — parses auth.log every scan | Not included — write a custom plugin that tails auth.log |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Node down if the master cannot reach munin-node on port 4949 |
| Public status page | Shareable URL with 90-day history | Internal CGI graph UI — not a customer-facing status page |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | Not included |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — add another tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | Web graphs and optional email from munin-limits |
| Learning curve | None — works after install | Medium — plugin config, field.warning, master/node firewall, CGI rendering |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Admins who already like Debian munin graphs and will write plugins |
Keep Munin when you already want that exact job:
value.value 42 and want those graphs forever.The package is free. A working ops loop is not:
For a 5-server team, Tink Mechanic at $45/month is cheaper than the first weekend spent wiring munin.conf, plugins, and CGI graphs, and every scan includes a diagnosis Munin will never write.
No munin-node. No port 4949. One command install.
