Why incident management
When a client site goes down, the clock starts ticking
Sentinel automatically creates detailed incident records so your team can respond fast, track progress, and share updates with clients.
Every incident carries its own record: the root cause we detected, when it started, when it ended, and how long it lasted. Nothing is reconstructed after the fact.
- Automatic incident creation on any type of failure
- Full timeline with acknowledgment and resolution tracking
- Diagnostics including traceroute and HTTP headers

Features
Everything you need to manage incidents
Automatic detection
Incidents are created automatically for uptime failures, SSL expirations, DNS changes, keyword failures, JSON assertion failures, ping outages, port unreachability, and slow responses.
Incident timeline
Track every event from detection through resolution. See who acknowledged, what diagnostics were run, and when it was fixed.
Team acknowledgment
Team members can acknowledge incidents to signal they're working on it. No more duplicate efforts during outages.
Built-in diagnostics
Run traceroutes and inspect HTTP headers directly from the incident view. Diagnose root causes without leaving Sentinel.
Incident notes
Add notes to incidents for internal documentation. Record root causes, workarounds, and follow-up actions.
Regional awareness
See which regions are affected. Distinguish between localized network issues and full global outages.
By the numbers
Every failure gets a record
Six kinds of incident, one shared timeline, and history you can hand to a client three months later.

Incidents tracked
How does Sentinel create incidents?
Incidents are created automatically the moment a problem is detected. This covers uptime failures, SSL certificate issues, DNS changes, domain expiration, keyword failures, JSON or API response problems, ICMP ping outages, TCP port unreachability, and missed heartbeats or cron runs.
What is included in an incident timeline?
Each incident has an automatic timeline that tracks every event from detection through to resolution, along with the root cause and resolution notes. You get a complete record of what happened and when.
Who gets notified when an incident opens?
When an incident is created, Sentinel sends alerts through your configured channels, which can include email, SMS, Slack, Discord, and webhooks. Your team is informed the moment something breaks.
Does an incident tell me which regions were affected?
Yes. Because checks run from four global regions, an incident shows which regions detected the failure, so you can tell a localized network issue apart from a full global outage.
Can I add my own notes to an incident?
Yes. You can record root cause findings, workarounds, and resolution notes directly on the incident, building documentation you can reference later or share with clients.
How quickly are incidents detected?
It depends on your check interval, which is set per plan: on paid plans checks can run as fast as every 30 seconds, so incidents are opened soon after a problem starts. Multi-region consensus ensures the incident reflects a real failure rather than a transient blip.
