Know the moment
your services go down.
ACS Monitor goes beyond simple uptime checks. HTTP monitoring, ping, SSL tracking, and service port checks — all built into a complete infrastructure monitoring platform.
No credit card required. Free for up to 100 devices.
More than a status page
Four types of uptime monitoring built into every ACS Monitor instance. No plugins, no extras.
HTTP/HTTPS monitoring
Monitor websites and APIs for availability. Status code validation, content matching, and fast outage detection.
Ping monitoring
Detect unreachable devices and servers instantly with ICMP ping checks. Know within seconds when a host goes offline.
SSL certificate tracking
Get alerted before certificates expire. Track issuer, expiry date, and certificate chain validity automatically.
Service port checks
Monitor TCP, SMTP, DNS, SSH, FTP, POP3, IMAP, and MySQL services. Verify they respond on the correct ports.
Why teams outgrow basic uptime tools
Simple up/down checks only tell you half the story. ACS Monitor gives you the full picture.
Most uptime tools only check one thing
A basic ping check tells you a server is reachable, but what about the web server, the database, the mail service? You need to check every critical service, not just the host.
HTTP, ping, TCP, DNS, SMTP, and SSL checks in one platform
ACS Monitor checks every service that matters for availability. HTTP endpoints, database ports, mail servers, DNS resolution, and SSL certificate expiry — all monitored from a single dashboard.
Separate tools for uptime, network, and infrastructure
One tool for website checks, another for network devices, a third for server metrics. Three dashboards, three alert configs, three subscriptions.
One install covers every availability check
HTTP checks, ping monitoring, SSL tracking, and service port checks all run from a single platform. One dashboard, one alert pipeline, one place to check availability. Deploy in minutes with a single command.
Alert fatigue from simple up/down checks
A single dropped packet triggers an alert. A brief DNS hiccup sends you a notification at 3am. By morning, you've learned to ignore alerts entirely.
Consecutive failure thresholds prevent false positives
Configure how many consecutive failures trigger an alert. Recovery notifications confirm when services come back. Send alerts via Email, SMS, Slack, or webhooks. See our alerting documentation for full configuration options.
