The Log tab on the Monitor page is used to view Kyvos Manager, Kyvos Manager Access, Services logs, and Kyvos YARN Services.
Kyvos Manager Server Logs
The Kyvos Manager records all the events that occur and any errors associated with those events in the form of logs. Logs are an essential tool for monitoring and troubleshooting problems with your environment. All events record information, such as log level, time at which the event occurred, the source component that logged it, the computer on which the event occurred, and so on. Information in these logs helps you identify errors. The logs also provide information on the history of the events that occur over time.
For example, the following events are recorded in the logs.
