Fivenines.io is a lightweight Linux server‑monitoring SaaS that delivers high‑precision metrics, custom real‑time dashboards, and instant alerts via email, Slack, or Telegram. Track CPU, memory, disks, network, cron jobs, ports, and Docker containers in minutes with an open‑source agent. The interface lets you build unlimited real‑time dashboards or start from pre‑made templates so every teammate sees the metrics that matter without wading through clutter. Threshold‑ or cron‑based rules are written in plain English, and alerts arrive the moment something drifts via email, Slack, or Telegram. Beyond resource statistics, the platform also watches cron jobs and specific server ports, giving you end‑to‑end confidence that scheduled tasks run and public endpoints respond.
