Event analytics
Events are essential raw data that Davis (the DESK AI engine) considers during automated root-cause analysis to understand the reasons underlying any problems that are detected in your environment. Out-of-the-box, Davis detects more than 80 different built-in system event types, including process crashes, deployment configuration changes, and VM motion events. Using extension points, you can report custom events through OneAgent plugins or via the DESK API.
Davis shows all system events in the context of your data center topology. So you can analyze events in relation to their parent topological components (for example, hosts, processes, or services) and see how they relate to one another.
The Events section
The Events section on each host, process, and service overview page provides a chart that displays overall statistics for each event type that occurred during the selected analysis timeframe.
Scaling up and drilling down
Within production environments, a single host, or even a single process, may include thousands of individual events. The DESK event-analytics engine can process all such events, even over large analysis timeframes. Importantly, event analysis offers convenient drill-down and filtering options that make it easy to focus on specific points in time where high event activity occurred and then filter those events based on event type.
The Events chart in the example below shows multiple event types over the course of a year-long analysis timeframe. However, the example below focuses on a single point in time and a specific event type. By drilling down into the event highlighted below, we see that the file ase.jsp was newly deployed at this point in time.
Push events from third-party systems
By enabling Davis to consider information from third-party systems, you can have custom events pushed to any topological component (host, process, or service).
One popular use case is to have your continuous integration (CI) and build toolchain automatically report meta-information about software deployments. Each custom event includes a set of custom key-value properties that your toolchain can use to report important context information.
In the example below, you can see a custom deployment event with user-defined key-value properties for the Jenkins build number and Git commit information.
