# Logging startup events

NMS OAM automatically maintains the following event logs on each host:

File name | Description
--- | ---
startup.log | A list of all NMS OAM events that occurred when the host started. This file is rewritten whenever the host starts. It is closed after the host starts.
oam.rpt | Low-level report information generated whenever a board is started. Information about each board is appended to the file when the board is started. The file is rewritten when the host is started.

On the host, the files can be found in the following locations:

- Windows: \nms\oam\log

- UNIX: /opt/nms/oam/log
