Sentinely guides
Step-by-step monitoring for Linux servers, Docker hosts, cron jobs and AI agents, written for the people who get paged.
Monitor CPU, memory, disk and services on Debian 12 Bookworm, comparing a Prometheus and Grafana stack with the one-command Sentinely agent install.
Hetzner's console only shows whole-VPS graphs. Monitor a Docker host on Hetzner with host metrics, uptime checks and heartbeats, without Prometheus.
Go beyond the basic Droplet graphs: monitor the host, uptime and background jobs behind your Node.js app on DigitalOcean, with alerts that reach you.
Monitor CPU, memory, disk and services on an Ubuntu 22.04 LTS server, from a manual Prometheus and Grafana setup to the one-command Sentinely agent.
Track CPU, memory, disk I/O and services on Ubuntu 24.04, comparing a Prometheus and Grafana stack with the one-command Sentinely agent install.
An honest comparison of Datadog and Sentinely for small teams: what each one covers, what Sentinely does not do, and how flat pricing compares in practice.
Monitor a Raspberry Pi running Docker: host CPU, memory, disk and network with the ARM64 Sentinely agent, plus uptime checks and heartbeats for containers.
