Website monitoring

Know your website is down before your users do

Monitor websites, APIs, ports, DNS and SSL certificates from distributed probes in China and overseas. Consecutive failure and recovery thresholds filter transient noise before an incident enters your alert workflow.

The free plan starts at a 5-minute interval. Sign in to save the monitor and start scheduling.

Monitoring capabilities

HTTP, Ping, TCP, DNS and SSL website monitoring

Protocol-specific configuration keeps website, network, port, DNS and certificate failures distinct.

HTTP(S) monitoring

Continuously check website and API status and response time.

GET / POST · expected status codes · latency threshold

Ping monitoring

Track host reachability and latency from distributed probes.

Multi-probe checks · carrier and regional impact

TCP monitoring

Verify that a TCP connection can be established on a selected port.

Ports 1-65535 · connection failure detection

DNS monitoring

Continuously verify critical public DNS records.

A / AAAA / CNAME / MX / NS / TXT / SRV / PTR

SSL certificate monitoring

Track certificate health and reduce expiration risk.

Certificate status · independent schedule

Create your first monitor

Choose a protocol and target. Configure frequency, probe scope, incident thresholds and alerts on the next screen.

Incident workflow

Verify across probes, reduce noise and locate impact

Scheduled monitoring runs independently and separates transient network noise, regional anomalies and real incidents.

  1. 01

    Distributed checks

    Run across all probes, China, overseas or selected regions.

  2. 02

    Incident decision

    Evaluate consecutive failures, response status and latency thresholds.

  3. 03

    Event delivery

    An independent alert process sends failure and recovery events.

  4. 04

    Review and share

    Review checks, SLA, impact and incidents, then share status when needed.

Bring incident alerts into your daily workflow

Each monitor keeps the configuration, evidence and collaboration surfaces your team needs from detection through recovery.

Probe health breakdown

Compare success rate, average latency and P95 by carrier, region and province.

SLA and check history

Review 24-hour uptime, recent-state strips and individual check results.

Failure and recovery records

Track impact, cause, start time, acknowledgement and recovery state.

Public status sharing

Create a controlled public status link and decide whether the target is visible.

Website monitoring FAQ

Key details about protocols, intervals, probes, alerts and reporting.

What can Chahu monitor?

Chahu currently supports HTTP(S), Ping, TCP, DNS and SSL certificate monitoring. HTTP(S) covers websites and public APIs, TCP checks a selected port, and DNS supports A, AAAA, CNAME, MX, NS, TXT, SRV and PTR records.

How often can a monitor run?

Available intervals are 1, 2, 5, 10 and 30 minutes, or 1 hour. The free plan starts at 5 minutes; other plans can run as often as once per minute.

How are transient network issues handled?

Each monitor has consecutive failure, consecutive recovery and latency thresholds. Incidents and recoveries are created only after those thresholds are met, with probe, carrier and regional results used to show impact.

Where can checks run from?

Except for SSL certificate monitors, tasks can use all probes, China probes, overseas probes or selected regions, with carrier filters for China Telecom, China Unicom, China Mobile and overseas networks.

Which alert channels are available?

Email, Telegram, phone, SMS, WeCom, DingTalk, Feishu, Slack, Discord and custom webhooks are supported. A dedicated alert process delivers failure and recovery events.

How is monitoring different from a manual speed test?

A manual test is launched on demand for one-time diagnosis. Monitoring runs independently on a fixed schedule and produces SLA, check history, incident records and alert events.
