I am trying to import IIS W3C Web Server logs using the import log file feature of the ManageEngine Eventlog Analyzer. Instead of installing SFTP on all our web servers I have mapped the folders containing the logs to the computer which hosts the ManageEngine Eventlog Analyzer. These IIS logs are generated hourly. The IIS logs are in this format “u_ex15020509.log”.I have tried the following patterns.

u_exyyMMddHH

yyMMddHH

a_aayymmddhh               (this was recommend by ManageEngine Support)

The hours are 24 hour format but just in case I also tried all these patterns using hh for the hours.

It bring over the log file I choose when setting up the import log file settings and puts it in “C:\ManageEngine\EventLog\server\imported_localfiles” folder. After a few minutes it disappears and I cannot find it anywhere. Additional it does not save the patterns I add, I do not know if this is intended or a permissions issue on the folder where it save the settings. Please advise me on what my next step should be to get these files imported.
