Tink vs Sensu

Sensu Go is a modern, event-driven monitoring pipeline — a common next step after Nagios for teams that want programmable checks and handlers. You still stand up a backend, roll out agents, and write or import check plugins before anything useful happens. Tink installs in one command, works immediately, and adds AI-powered diagnosis and fix execution that Sensu doesn't have.

The core difference: Sensu runs the checks you write. Tink finds, explains, and helps fix the problem.

Sensu is an event pipeline. Agents execute checks, the backend stores events, and handlers fan those events out to Slack or PagerDuty. When a check goes critical, someone still has to open a terminal, read the output, find the root cause, and run the fix. Tink does those steps for you — it detects the issue, explains the likely cause in plain English, proposes specific commands, and executes them with your approval.

That gap matters most for small teams that evaluated Sensu as a Nagios replacement and then realized they still needed an engineer to design the monitoring system.

When Sensu is the right choice

Sensu genuinely excels in environments that are outside Tink's target:

  • Programmable monitoring as code — Sensu checks, handlers, and assets are first-class config. If your team already treats observability as a software project, that model fits.
  • Custom check plugins at scale — You can wrap any script as a Sensu check and reuse it across subscriptions. Tink ships a focused Linux health set, not a plugin SDK.
  • On-premises data residency — Self-hosted Sensu keeps events on your network. Tink is SaaS with data in Neon/Vercel infrastructure.
  • Existing Nagios-style check inventory — Many Nagios plugins run as Sensu checks with little change. Migrating that library to Tink would mean giving up custom coverage.
  • Sumo Logic / enterprise event routing — Teams already standardized on Sensu plus Sumo Logic get a pipeline Tink is not trying to replace.

The real cost of “free” Sensu Go

Sensu Go's core is open source, but you still own the pipeline:

  • A sensu-backend host plus etcd (or a clustered pair) — typically $15-40/month in cloud VMs before HA
  • Half a day to stand up backend, TLS, users, and the first agent subscription
  • Time to write or import checks for disk, memory, CPU, services, certs, and auth logs
  • Ongoing handler and silencing maintenance when alerts get noisy
  • Commercial Sensu features (or a separate incident tool) if you need enterprise support

For a 5-server team, Tink Mechanic at $45/month is cheaper than the engineering time to design a Sensu check catalog — and each Tink scan includes AI diagnosis that Sensu events do not provide.

Predictive alerting: Tink warns before a check goes critical

Sensu tells you when a check exits non-zero. Tink also tells you when the machine is heading there:

  • Disk trend alert — “At the current growth rate, /var will be full in approximately 6 days” — fires before any threshold is crossed
  • Memory trend alert — Detects memory creep across 4 scan windows and warns before the 96% critical threshold
  • Baseline anomaly detection — Fires when any metric is 2.5 standard deviations above the machine's own historical mean

A Sensu check going critical means the house is already on fire. Trend alerting tells you the smoke detector smelled something 6 days earlier.

No backend. No check plugins. No ops certification required.
