What is Sentinel by Rootstuff?
Sentinel provides a thorough hosted monitoring service for websites, APIs, and network services. It conducts a wide range of assessments, including checks for HTTP/HTTPS, JSON/API, keyword tracking, SSL certificate verification, DNS resolution, domain expiration monitoring, ping tests, TCP port checks, cron job execution, and heartbeat verifications, all while delivering insights on response times and status pages that are accessible to the public. These evaluations can be performed as often as every 15 seconds from 15 distinct geographical locations across six continents, allowing for comprehensive outage notifications through multi-site verification. Teams can receive real-time alerts via various platforms like email, SMS, Slack, Microsoft Teams, Discord, Telegram, PagerDuty, and webhooks to stay updated on service status. In addition, Sentinel offers a REST API, command-line utilities, a Terraform provider for infrastructure management, and an MCP server to support automation tasks. A free plan is available, while paid subscriptions start at $14 monthly, which includes API access without extra fees based on user count. This service is designed for developers, DevOps, and SRE teams, as well as businesses needing dependable monitoring of their service uptime, making it a flexible solution for sustaining high performance across online platforms. Moreover, the extensive capabilities of Sentinel are tailored to improve operational workflows and guarantee that essential services remain active and efficiently functioning.
