Envoh monitors environments, servers and SSL/TLS certificates. Group servers by environment, track health signals and view reports sent by your applications. Environments and servers Organize production, staging and development environments. View health summaries, filter by status and identify which monitoring signal needs attention. Server Check Check an endpoint. Configure its path, headers, normal and retry intervals, and how many consecutive failures trigger a notification. Review the latest result. Heartbeat Configure servers, scripts or containers to send Heartbeats to Envoh. View the latest Heartbeat and receive notifications when none arrives within the configured timeout. Telemetry View CPU usage, memory usage, disk space and network quota consumption. Configure warning and critical thresholds and notifications for each resource. Your server or an agent you configure must send measurements through the Envoh API. Envoh evaluates the data you provide. Server Signals and Catch Events Your applications send reports and critical events through the Envoh API. Open recent events from the home screen to view their title, subtitle, server, status and content. - Server Signals support text, Markdown, tables, and bar, line and pie charts. - Catch Events record critical occurrences with text content. - Each participant can mark an event as looking into it, needing help or resolved. SSL/TLS certificates Track certificate status and expiration dates across your domains. Choose how many days before expiration you want to receive notifications. Sort and filter your own and shared certificates. Sharing Use Share Keys to share an environment or selected certificates. Shared participants can view monitoring data and collaborate on events. Notifications and plans Notifications depend on service settings, plan limits and notification permissions on your devices. Basic is free. Paid plans increase capacity and allow shorter monitoring intervals.
