The simplification of infrastructure and endpoint monitoring has reached unprecedented ease! After Monitis ceased operations following its acquisition by TeamViewer last year, we urgently sought a viable alternative. We evaluated numerous options, such as Uptrends, Datadog, dotcom-monitor, CloudRadar, Pingdom, and Uptime, but ultimately decided to develop our own solution, focusing on specific requirements: a cloud-based SaaS platform, a small and efficient agent, a straightforward setup process, adaptable pricing, effective maintenance windows, city-level geotargeting, embeddable graphs, real-time alert notifications, comprehensive process monitors with rollup features, and audible alerts directly on our dashboard. At the heart of our solution lies a compact server agent, measuring just 2.1 MB, which, once installed and connected, sends a "heartbeat" report to our ingest API every minute within your network. This innovative approach enables users to meticulously monitor, analyze, and improve their website’s performance as well as the overall experience for end-users, ensuring that all essential elements are effectively managed. The integration of these features provides a customized monitoring experience that caters to a variety of specific requirements, demonstrating our commitment to meeting the diverse needs of our users.
