FourSight
FourSight is multi-region uptime monitoring built to stop alert fatigue. Every check runs from four regions (US, Canada, Europe, Asia-Pacific) and a quorum-based consensus policy confirms an outage from more than one region before anyone is paged, so a single flaky vantage point never wakes you at 3 AM. Eight check types cover HTTP/uptime, keyword/content, SSL certificate expiry, DNS drift, domain expiry (RDAP), ping latency, TCP/UDP port checks and heartbeat monitoring for cron jobs and backups. Alerts go out by email, Slack, HMAC-signed webhooks and SMS, with escalation policies and maintenance windows to keep noise down. Public status pages are included on every tier (white-label with custom domains on Scale), plus incident management with timelines, multi-user organizations with roles, and uptime/latency history with regional breakdowns.

BoxWatch
BoxWatch is server monitoring that does the job of four tools at once: metrics, cron heartbeats, uptime checks, and process monitoring. One agent, one dashboard, one bill.
Most teams stitch together Datadog (or similar) for metrics, Healthchecks.io for cron, UptimeRobot for HTTP checks, and a separate supervisor for processes. BoxWatch replaces all of that.
Metrics: CPU, memory, disk, network, load, and uptime, collected by a small open-source bash agent installed with one curl command. Trend charts, side-by-side comparison views, and disk-full prediction that warns you days before a volume actually fills.
Cron heartbeats: ping a URL when a job finishes, get alerted when the ping is late or missing. Four alert types with transition-based dedup so you never get spammed.
Uptime checks: HTTP, TCP, and TLS-expiry probes executed by your own deployed BoxWatch agents.
