Description

Sentinel offers a comprehensive hosted monitoring solution for websites, APIs, and network services. It performs a variety of checks including HTTP/HTTPS, JSON/API, keyword monitoring, SSL certificate validation, DNS resolution, domain expiration tracking, ping, TCP port monitoring, cron job execution, and heartbeat checks, all while providing response-time analytics and publicly accessible status pages. These checks can be executed as frequently as every 15 seconds from 15 different geographical locations spanning six continents, ensuring multi-location verification for outage notifications. Teams can receive alerts through various channels such as email, SMS, Slack, Microsoft Teams, Discord, Telegram, PagerDuty, and webhooks to keep them informed in real-time. Additionally, Sentinel includes a REST API, command-line tools, a Terraform provider for infrastructure management, and an MCP server to facilitate automation processes. There is a complimentary plan available, whereas paid subscriptions begin at $14 per month, offering API access without additional charges based on the number of users. This service caters to developers, DevOps and SRE teams, and organizations that require reliable monitoring of their service availability, making it a versatile tool for maintaining optimal performance across digital platforms. Furthermore, its robust features aim to enhance operational efficiency and ensure that critical services remain online and functional.

Description

While many uptime monitors simply verify server responses, upsonar takes it a step further by fully loading your webpage to identify all external components, including CDN-hosted assets, third-party scripts, web fonts, and API endpoints. Should any of these elements fail, you receive timely alerts, ensuring you can address issues before your users experience them. Additionally, availability checks are performed from numerous locations worldwide simultaneously, which helps ensure that any regional CDN failures or localized outages do not go unnoticed. In addition to monitoring uptime, upsonar keeps an eye on SSL certificates nearing expiration, tracks the expiration dates of domains to avoid renewal issues, and identifies changes in DNS records that could signal unauthorized alterations. The five types of monitoring operate cohesively within a single dashboard, offering you a streamlined overview. Notifications can be sent via email, Telegram, or through webhooks that integrate seamlessly with platforms like Slack, Discord, and PagerDuty. You can begin with a free plan that allows monitoring of three websites, complete with all features and no credit card required, making it easy to experience the full benefits without commitment.
