Question 1

What does FourSight monitor?

Accepted Answer

FourSight supports eight monitor types: HTTP/HTTPS uptime, keyword/content presence, DNS records, SSL certificates, domain expiry (via RDAP), ping (TCP latency & packet loss), port monitoring (TCP/UDP with banner check, send/expect regex, and service presets for SMTP, IMAP, FTP, SSH, DNS & more), and heartbeat/cron monitoring (for background jobs, scheduled tasks, and webhooks). All checks run from four global regions.

Question 2

How often do checks run?

Accepted Answer

Check frequency depends on your plan. Free plans check every 5 minutes. Starter plans check every 1 minute. Growth and Pro plans check every 30 seconds. Scale plans check every 15 seconds. Heartbeat monitors support fixed intervals or custom cron expressions (up to 5-field format). All plans include multi-region validation from US, Canada, Europe, and APAC.

Question 3

What monitor types are available on each plan?

Accepted Answer

Free and Starter plans include HTTP and Ping monitors. Growth, Pro, and Scale plans unlock all eight types: HTTP, Ping, SSL, DNS, Domain Expiry, Keyword/Content, Port monitoring, and Heartbeat/Cron monitoring with full protocol validation.

Question 4

How does multi-region monitoring work?

Accepted Answer

Every check runs from probes in four regions: US, Canada, Europe, and APAC. Results are validated against geographic constraints and aggregated using a quorum-based consensus policy (e.g., majority voting). This eliminates false positives caused by regional network issues — a single region going down won't falsely alert your team.

Question 5

What notification channels are available?

Accepted Answer

FourSight supports four notification channels: Email (rich HTML templates), Slack (Block Kit formatting with status emojis and deep-link buttons), Webhooks (JSON payloads with optional HMAC-SHA256 signing and exponential backoff retries), and SMS (via E.164 phone numbers with carrier-compliant opt-in). You can configure rules per monitor and severity level.

Question 6

How do alerts and incidents work?

Accepted Answer

When a check fails across enough regions to meet quorum consensus, FourSight automatically creates an incident with a severity level (critical, major, or minor) and sends alerts to your configured notification channels. The incident timeline tracks every status change — investigating, identified, monitoring, resolved — with timestamps. Recovery alerts are sent when the issue is resolved.

Question 7

What are maintenance windows?

Accepted Answer

Maintenance windows let you schedule planned downtime to suppress alerts and incident creation. You can create one-time windows or recurring schedules (daily, weekly, monthly) using RRULE patterns. Maintenance can target specific monitors or entire status pages, and active windows are visually indicated across the dashboard and public status pages.

Question 8

Do you have public status pages?

Accepted Answer

Yes. Every plan includes at least one public status page. Starter includes 2, Growth includes 5, Pro includes 10, and Scale includes 25. Pro and Scale plans support custom CSS for full brand matching.

Question 9

Do you support teams / multiple organizations?

Accepted Answer

Yes. All plans support organizations with role-based access (owner, admin, member). Each organization has its own monitors, status pages, notification rules, maintenance windows, and billing.

Question 10

Can I see historical uptime and incidents?

Accepted Answer

Yes. Free plans retain 24 hours of history. Starter plans retain 14 days. Growth plans retain 30 days. Pro plans retain 90 days. Scale plans retain 1 year. Latency charts support per-monitor trends and regional breakdowns.

Question 11

How is pricing structured?

Accepted Answer

Plans are flat-rate based on monitor count: Free (10 monitors, $0), Starter (50 monitors, $16/month), Growth (100 monitors, $40/month), Pro (250 monitors, $80/month), Scale (500+ monitors, $160/month). No per-monitor charges or hidden fees. The Free plan is permanent — no credit card, no trial expiration.

Question 12

Can I pause monitors?

Accepted Answer

Yes. You can pause any monitor temporarily without deleting it. Paused monitors don't run checks. Resume them anytime with a single click.

Question 13

What is port monitoring?

Accepted Answer

Port monitoring lets you check TCP or UDP ports on any host. It supports three validation modes: connect-only (just verify the port is open), banner check (read the initial response), and send/expect (send a string and match the response with regex). Presets are available for common services like SMTP (25), POP3 (110), IMAP (143), IMAPS (993), FTP (21), SSH (22), and DNS (53).

Question 14

What is heartbeat monitoring?

Accepted Answer

Heartbeat monitoring (also called cron or script monitoring) tracks recurring signals from background jobs, scheduled tasks, APIs, webhooks, or any external service. You set an expected interval or cron schedule, and FourSight alerts you if a ping is missed or arrives outside your grace window. Perfect for batch processes, cleanup jobs, and health check endpoints that must run on schedule.
