InfluxDB Cloud offers a powerful feature called "Deadman Check" that allows users to set up automated tasks to monitor for sudden shocks or delays in the flow of incoming data, and can alert them through third-party messaging platforms. To create this check, users navigate to the "Alerts" section in InfluxDB Cloud 2.0, select the "Deadman Check" type, define the query and configure the settings, including scheduling, status message, and deadman threshold. Users then need to configure a Slack App as an endpoint and create a notification endpoint, before creating a notification rule that triggers when the check detects a deadman scenario. This feature is particularly useful for monitoring large amounts of historical data or smart home devices, and can help prevent service outages from causing significant disruptions.
