Dotcom-Monitor

Dotcom-Monitor is a synthetic monitoring platform built around web application monitoring, using real-browser testing to confirm that websites, web applications, and APIs work correctly for actual users. Founded in 1998 and based in Minnesota, it runs checks continuously from more than 30 locations across 6 continents, combining outside-in visibility with private, behind-the-firewall monitoring in one platform. Web application monitoring is the core. The EveryStep Web Recorder captures multi-step user journeys without coding, so teams can monitor login, search, cart, and checkout flows the way customers experience them. Scripts run in real browsers with full JavaScript rendering, validating dynamic content and single-page applications, not just whether a home page responds. Page-load waterfalls, element-level timing, and performance reports show where a transaction slows down or breaks, and screenshots and video capture the exact failure for faster diagnosis. API monitoring covers REST, SOAP, and GraphQL endpoints, along with imported Postman and Insomnia collections. Multi-step API workflows chain requests and pass dynamic data between calls, while response checks validate JSON and XML payloads using JSONPath and XPath. Authenticated monitoring supports OAuth 2.0, JWT, API keys, Basic Auth, mTLS, AWS Signature, NTLM, and Kerberos, so protected and production-grade APIs can be tested end to end. Monitoring can also be created and controlled through a REST API, so checks run inside CI/CD pipelines and gate releases before deployment. Server, infrastructure, and network monitoring round out the platform. Checks cover HTTP and HTTPS, DNS resolution and record validation, SSL certificate validity and expiration, email services (SMTP, POP3, IMAP), FTP and FTPS, TCP ports, WebSocket connections, SIP and VoIP systems, and streaming media. Uptime monitoring verifies availability from multiple locations and confirms failures from more than one site before alerting, which reduces false positives. Private Agents extend the same checks inside data centers, private networks, and staging or pre-production environments, so internal applications and services behind the firewall receive the same coverage as public endpoints, using outbound HTTPS without inbound firewall changes. Results surface in real-time dashboards, historical performance reports, and waterfall charts, and alerts route to Slack, Microsoft Teams, PagerDuty, Opsgenie, ServiceNow, VictorOps, xMatters, email, SMS, phone, and webhooks. Escalation policies, on-call schedules, and maintenance windows keep notifications targeted, and acknowledgment and resolution tracking keep incident state clear. Common use cases include verifying login and authentication, validating e-commerce checkout and payment flows, tracking SaaS application performance, monitoring API endpoints against service-level targets, preventing SSL certificate expirations, and detecting DNS resolution problems early. The platform is often run as a primary synthetic monitoring system and as a complement to observability tools, confirming that applications behave correctly from the end-user perspective rather than only that infrastructure is healthy. Dotcom-Monitor serves DevOps, site reliability, platform, and IT operations teams, along with QA and web engineers, at organizations of all sizes. It is used across e-commerce and retail, financial services and fintech, SaaS and cloud platforms, healthcare and telemedicine, media and entertainment, and government and the public sector, wherever reliable validation of application performance and availability across complex user workflows matters. By combining real-browser web application monitoring, API monitoring, and infrastructure monitoring with both public and private deployment options, the platform gives teams a single view of how their digital services behave for users around the world
