Documentation
Everything you need to start monitoring with Canary9: create your first check in a couple of minutes, then lock down your account.
Guides
Monitoring endpoints
Create endpoints, pick a check type (HTTP, TCP, ping, DNS, browser), and read uptime & response-time data.
Diagnostic chains
Run on-demand network diagnostics from the probe's location to find out why an endpoint is down or slow.
Alerts & notifications
Set the conditions and thresholds that decide when a check counts as down, and review the event log.
Troubleshooting
What to check when an endpoint reports down, blocked, slow, or silent, and how to unblock bot-managed sites.
Integrations
Send alerts to Slack, PagerDuty, and Jira, and route them with @-mention handles.
Public API
Manage endpoints, alert policies, and integrations programmatically with a scoped API key.
MCP server
Manage endpoints, alerts, and integrations from Claude, Cursor, or any MCP client.
Two-factor authentication
Add a second factor with any authenticator app and keep backup codes for recovery.
Account & team
Manage your profile, display preferences, your organization, and teammates & roles.
