Problem:
How to make the log files not so big for TM1?
Can i have tm1top data logged to a file?
Solution:
Create the tm1s-log.properties file in the same folder as your tm1s.cfg file.
log4j.appender.S1.MaxFileSize=10 MB tells how big your tm1server.log file will be, default is much larger.
log4j.appender.S1.MaxBackupIndex=40 is the number of files that will be kept. Increase this to the value you need.
To enable TM1TOP data, without using the tm1top utility, add to your tm1s.cfg file
TopLogging=T
Then active and set the filename with this parameters in tm1s-log.properties file:
log4j.logger.Top=INFO, S_Top
log4j.appender.S_Top=org.apache.log4j.SharedMemoryAppender
log4j.appender.S_Top.MemorySize=5 MB
log4j.appender.S_Top.File=tm1top.log
log4j.appender.S_Top.Format=TM1Top
Then in the tm1s-log.properties file you adjust the size with the parameters:
log4j.appender.S_Top.MaxFileSize=10 MB
log4j.appender.S_Top.MaxBackupIndex=20
This is a great example of a tm1s-log.properties file that is copied from https://www.ykud.com/blog/cognos/tm1-cognos/tm1s-log-properties/
