FAQ
Short answers first, with the page that has the full story linked from each.
What can Monitorable monitor?
Section titled “What can Monitorable monitor?”Linux servers — bare metal, VMs, and LXC containers, on x86_64 (amd64) or arm64. One collector per server reports host metrics, Docker containers, systemd services, and — on bare metal — SMART disk health.
Does it work on Windows or macOS?
Section titled “Does it work on Windows or macOS?”No. The collector is Linux-only — Requirements & permissions lists what the server needs.
Is it really OpenTelemetry?
Section titled “Is it really OpenTelemetry?”Yes. The collector is a custom distribution of the OpenTelemetry Collector, and metrics leave your server as standard OTLP over HTTPS. What the collector collects lists every field on the wire.
How much load does the collector add?
Section titled “How much load does the collector add?”The binary is about 47 MB on disk; running, it holds 12–16 MB of memory and has averaged under 0.1% of one CPU core on the server these docs are verified against — measured numbers, not targets, in Requirements & permissions.
How quickly do metrics appear?
Section titled “How quickly do metrics appear?”The first batch arrives about 60 seconds after the collector service starts. Panels fill as their data comes in: containers within a minute, services within about 5 minutes, disk health within a few minutes on bare metal. The Quick start walks the whole first run.
Does Monitorable ping my servers from the outside?
Section titled “Does Monitorable ping my servers from the outside?”No. All monitoring comes from the collector’s outbound reports — there are no external probes, and nothing connects to your server. “Offline” means the collector stopped reporting, which is what the Collector offline alert rule fires on.
How long is my data kept?
Section titled “How long is my data kept?”Per-minute detail for 35 days, hourly history for 400 days — Metrics history & resolution covers the switchover and what deletes data.
What does it cost?
Section titled “What does it cost?”Monitorable is free for 3 servers — 14 days of history and alerting to email, Telegram, and Discord, with no card required. Paid plans are a flat monthly price by tier: Pro $9/month (10 servers), Scale $29/month (40 servers), and Enterprise $79/month (150 servers), each adding history, alert channels, templates, and team seats. Every paid plan starts with a 14-day free trial, and annual billing is two months free. The pricing section has the full breakdown.
Are there limits on servers or alerts?
Section titled “Are there limits on servers or alerts?”Yes — each plan sets them. Servers run from 3 on the free plan to 150 on Enterprise; alert channels from 3 to unlimited; alert templates from 3 to unlimited; team members from 1 to 25. The plan also sets how far back the dashboard can query — from 14 days to a year — which is a query window, not when data is deleted (see How long is my data kept? above). The pricing section lists every tier, and the per-channel notification caps are on Notification channels.
Is there a public API?
Section titled “Is there a public API?”Not yet. The dashboard is the only interface today; an API is on the roadmap but unscheduled.
