FiveNines is a complete monitoring platform for Linux engineers who need infrastructure visibility without the setup tax. Server metrics with 5-second precision, website uptime checks from multiple regions, cron job monitoring, network device polling via SNMP, public status pages, and automated alert workflows - all from one dashboard. Our open-source agent installs in one command. Uptime monitors start checking in seconds. Alerts reach you via Email, Slack, Telegram, Discord, Pushover, or webhooks. Whether you're managing 5 homelab servers or 100 production nodes with uptime monitors and network devices, FiveNines replaces the patchwork of Prometheus, UptimeRobot, and healthchecks.io with a single platform that works out of the box.

FAQ
Frequently Asked Questions
How long does it take to set up Fivenines?
Setup takes about 2 minutes. Install the lightweight agent on your Linux server with a single command, and metrics start appearing in your dashboard within 60 seconds. No configuration files to edit, no dependencies to install.
What Linux distributions does Fivenines support?
Fivenines supports Ubuntu, Debian, Rocky Linux, AlmaLinux, Arch Linux, CloudLinux, CentOS, and most other mainstream Linux distributions. The open-source agent is designed to work across the Linux ecosystem.
Does FiveNines have an API and Terraform provider?
Yes. The public REST API lets you manage hosts, uptime monitors, network devices, workflows, incidents, and integrations programmatically. The Terraform provider (available on the Terraform Registry) lets you define your entire monitoring setup as code and version it alongside your infrastructure.
Does FiveNines monitor website uptime?
Yes. FiveNines checks your websites and APIs from multiple regions worldwide, measuring response time, SSL certificate status, and availability. When a check fails, quorum confirmation from other regions prevents false alerts. You can also create public status pages for your customers.
How is Fivenines different from Prometheus and Grafana?
Prometheus and Grafana are powerful but require significant setup and maintenance - configuring scrape targets, writing PromQL queries, building dashboards, and managing storage. Fivenines is a fully managed service: install the agent and everything works out of the box. No infrastructure to maintain, no query language to learn.
Is there a free plan?
Yes. The free plan includes 5 monitors (servers, tasks, uptime, or network devices), email alerts, and 1 month of data retention. No credit card required. All paid plans start with a 14-day free trial.
What alert channels does Fivenines support?
Fivenines sends alerts via email, Slack, Telegram, Discord, Pushover, and webhooks. You can route different alerts to different channels and set custom thresholds for every metric.
Can I automate alerts with workflows?
Yes. FiveNines workflows let you build visual automation graphs: triggers fire on metric thresholds, host status changes, or missed heartbeats. Add conditions, delays, recheck loops, and route notifications to any channel. Workflows replace static alert rules with flexible, multi-step automation.
