Overmonitor
Overmonitor
Infrastructure and endpoint monitoring made easy! After Monitis ceased its services last year (sold to TeamViewer) we were left scrambling for a replacement solution. We evaluated Uptrends, Datadog, dotcom-monitor, CloudRadar, Pingdom, and Uptime and came up with our own solution based on the following requirements: Cloud-based SaaS solution, small and lightweight agent, fast configuration interface, a la carte pricing model, maintenance windows that work, geotargetting at the city level, all graphs embeddable, push notifications for any alert, process monitors with rollup, and audible dashboard alerts. At the heart of our solution is a small (2.1 MB) and lightweight server agent. Once installed and "paired" it will start reporting a "heartbeat" once per minute to our "ingest" API from inside your network. Monitor, analyze, and improve website performance and end-user experience.Starting Price: $2.50 per month -
