CheckCle Uptime and Infrastructure Monitoring

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview

CheckCle is a self-hosted, open source uptime and infrastructure monitoring platform delivered as a pre-hardened AMI by cloudimg. Launch an EC2 instance and have a private monitoring dashboard operational in minutes - no manual Docker installation, no nginx configuration, no database wiring. Focus on monitoring your systems, not building the monitoring stack.

Who Is This For?

This product is ideal for solo operators, small DevOps and SRE teams, MSPs, and startups who need a single pane of glass for uptime, SSL certificate, server, and service health without standing up a heavyweight observability platform. Whether you are watching a handful of endpoints or a fleet of servers and services, CheckCle scales from a single site to a full estate.

What You Get That Self-Deploy Does Not

Unlike launching raw open source CheckCle on your own EC2 instance, this AMI eliminates the manual steps that slow teams down and introduce security risk:

• No shared default credentials - A one-shot service rotates the administrator password to a unique per-instance value on first boot, stored in a root-only file. The upstream factory credential is never reachable on port 80.
• Pre-configured nginx reverse proxy - WebSocket and Server-Sent-Events support for live dashboards, ready for TLS termination with your own domain.
• Dedicated data volume - Monitoring history and the embedded SQLite database live on an independently resizable EBS volume, separate from the OS disk.
• Docker container on loopback - The application binds to localhost until credential rotation completes, reducing attack surface.
• 24/7 cloudimg support - Unlike community-only support for the open source project, you get direct access to engineers for upgrades, TLS setup, and troubleshooting.

Application Stack

CheckCle runs as a single Docker container bundling a PocketBase backend (embedded SQLite datastore, REST and realtime API, admin dashboard), the CheckCle web frontend, and a monitoring worker. The container is fronted by nginx as a reverse proxy. The current release is CheckCle 1.6.

Key Capabilities

• Uptime, SSL certificate, server, service, ping, TCP, DNS, and cron monitoring
• Incident tracking, alerting, and configurable notifications
• Public status pages for real-time availability reporting
• Realtime web dashboard backed by an embedded database - no external database required
• Data stored on a dedicated, independently resizable EBS volume

Security Posture

This build addresses common AMI security gaps:

• Per-instance credential generation eliminates the shared-password risk present in many marketplace images
• Application binds to loopback until hardening completes, so the well-known default is never network-reachable
• Recent upstream fixes include a CWE-922 remediation for insecure storage of sensitive information
• Root-only file permissions on the generated admin password

Example Use Case

A growing SaaS team launches this image, signs in to the dashboard, and adds HTTP, ping, TCP, and DNS checks for their public endpoints plus SSL certificate expiry monitors for their domains. They configure alerting and a public status page so customers see real-time availability and the on-call engineer is notified the moment a check fails - all without deploying Prometheus, Grafana, and a separate status-page service.

Getting Started

1. Launch the AMI on your chosen EC2 instance type

2. Retrieve the generated admin password from the root-only file

3. Sign in to the CheckCle dashboard via your instance's public IP

4. Add your first monitor - uptime, SSL, server, ping, TCP, DNS, or scheduled task

5. Configure alerting channels and publish a status page

The pre-configured nginx reverse proxy means your dashboard is reachable immediately and ready for TLS termination when you attach your own domain.
