Dynatrace supports different categories of Davis events, where each Davis event comes with an event type and a severity (significance) level.
In order from most to least severe, the Davis event categories supported in Dynatrace are as follows:
Monitoring unavailable events indicate a widespread monitoring interruption, where the majority of your installed OneAgents lose their connection with the Dynatrace server. This usually manifests itself as a lack of visibility in terms of both availability and performance monitoring.
Availability events indicate high-severity incidents within your environment, such as a complete outage or unavailability of servers or processes.
Error events inform you of increased error rates or other error-related incidents that interfere with the regular operation of your environment.
Slowdown events indicate a decrease of performance in one of your operational services or applications.
Resource events indicate resource contention. Typical examples:
Custom alerts are used to enable alerting on any user-defined thresholds.
Info events indicate manually triggered Davis events that don't result in the creation of a new problem, such as:
Informational Davis events aren't sent out as alerts and no problems are opened, as this category of Davis events doesn't indicate an abnormal situation.
Warning events inform you that something might become a problem in the near future.
