# Logging startup events

NMS OAM automatically maintains the following NMS OAM 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 when 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. Note: For users migrating from agmon, this file is the NMS OAM equivalent of the ag.rpt file generated by agmon.

On the host, the files are found in the following locations:

- Windows: \nms\oam\log

- UNIX: /opt/nms/oam/log
