Hi,
I observe the performance issue of nxlog-ce in windows OS (win7 & 2008
bit64).
I use the im_file module to monitor a directory which has many text file.
If the directory has more than 3 files, the nxlog will cause high CPU
usage(70~80%, single core).
P.S. Only write one file, but there are another text file in this directory
And then I try to use im_exec to monitor specific text file.
I use tail.exe (from win2003 resource kit) in this test.
When I start nxlog service, the cpu usage become very high immediately.
(90~100%, single core)
I have not yet written anything into this text file.
I try to use Python Script, and the script will do nothing.
The situation is the same in this case.
I don't know why the nxlog cause high cou usage.
The nxlog.log doesn't have error message.
What do I need to do to solve this problem?
Thank you very much.
Below is my setting in nxlog.conf
---------------------------------
<Input file_in>
Module im_file
File z:\\iis\\u_ex*.log
Recursive FALSE
ReadFromLast TRUE
InputType LineBased
</Input>
<Input exec_input>
Module im_exec
Command z:\\tail.exe
Arg -f
Arg z:\\test.log
#Command z:\\python27\\python.exe
#Arg z:\\do_nothing.py
InputType LineBased
</Input>
<Output udp_out>
Module om_udp
Host %SYSLOGSERVER%
Port %SYSLOGSERVERPORT%
</Output>
<Output file_out>
Module om_file
File "z:\\456.log"
</Output>
<Route 1>
Path file_in => file_out
#Path exec_input => file_out
</Route>
