nex-healthcheck

Multi-service health and uptime monitoring dashboard for websites, APIs, infrastructure, and applications across multiple systems. Monitor website availability and HTTP response codes with configurable status code validation, check SSL certificate expiration dates with advance warnings (30-day warning, 7-day critical threshold), verify DNS resolution and nameserver health for domain infrastructure. Monitor Docker container status and container-level health checks, track systemd service status on both local and remote machines via SSH, and perform network connectivity tests (TCP port connectivity, ICMP ping, SSH command execution with response validation). Configure flexible health checks including HTTP/HTTPS endpoint monitoring with custom ports, TCP port connectivity without HTTP, DNS resolution verification against multiple record types (A, AAAA, MX, NS), and complex remote checks through SSH including systemctl status queries and docker ps commands on remote infrastructure.
