 See information derived from the syslog audit trail, including successful and failed activities, successful and failed logon attempts. Additionally, this dashboard also provides insight around logon status trend, top current, and database users. This dashboard work with unified audit logs exported from both Windows and Linux environment.

-The Oracle - Performance & I/O dashboard gives insight about - session and process utilization against their limits, PGA memory allocation, and overall SQL execution versus parse rates. In addition to this, it monitors detailed I/O metrics around physical reads, write requests, and cache-bypassed direct I/O. This dashboard is based on the [metrics collected by Oracle DB opentelemetry receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/oracledbreceiver/documentation.md).
