I have a large app that uses log4cplus to create a log file for each disk drive
on a system - about 1000 files. We use nxlog to transfer files to a PC during
testing. (conf file fragment below).
It appears, with about 1000 files in the monitored directory, we take a 5%
performance hit overall. I haven't pinned it down to nxlog yet, but I did see
some notes in the latest release of nxlog that mentions wildcards monitoring.
There is very little writing to these files, as they are used for exception
logging only - maybe 1-2 writes to each file at the beginning of a 2 hr test
run.
I'm currently using 2.3.1027.
Thanks
Larry
