@kange0010 can you please provide more details? You posted this in the Log & Event Manager forum. Are you using that product or something like NPM? If you are using an Orion Platform based product such as Network Performance Monitor or Server & Application Monitor, then the logs can be found in C:\ProgramData\SolarWinds\Logs.
If you are running diagnostics, then a .ZIP will be created with what you need to send to Sales or Support.
See the relevant resources here:
SolarWinds Orion Platform and SAM log file locations - SolarWinds Worldwide, LLC. Help and Support
where are the debug log files?
If you aren't sure, sending screenshots of the product and / or file directory can usually help us get an answer to you faster.
