Configuring SL4J Logging

[andreiyusupau]

I have configured my quickfix j initiator to use SL4J for logging with following settings:

SLF4JLogEventCategory=DEBUG
SLF4JLogErrorEventCategory=ERROR
SLF4JLogIncomingMessageCategory=DEBUG
SLF4JLogOutgoingMessageCategory=DEBUG
SLF4JLogPrependSessionID=Y
SLF4JLogHeartbeats=N

So I've expected that only errors would be logged if my root log level is INFO.
But for some reasons messages like this are still logged:
13:47:54.286 INFO [main] DEBUG - FIX.4.4:xxx->yyy: Created session: FIX.4.4:xxx->yyy
Could it be some misconfiguration?

Hi @andreiyusupau ,

a category is not the same as the level. You could categorize log messages into categories, see https://github.com/quickfix-j/quickfixj/blob/master/quickfixj-core/src/main/java/quickfix/SLF4JLog.java

only errors would be logged if my root log level is INFO

Actually, this will also log INFO and events are logged at INFO level, see

quickfixj/quickfixj-core/src/main/java/quickfix/SLF4JLog.java

Line 114 in 36a07fe

public void onEvent(String text) {

and

quickfixj/quickfixj-core/src/main/java/quickfix/SLF4JLog.java

Line 135 in 36a07fe

protected void log(org.slf4j.Logger log, String text) {

Thanks for fast reply.
So if I understand correctly, I can't affect log levels of messages using settings (Created session: ... for example would be always INFO). And the only way to hide message logs for production environment would be setting higher level for quickfix package (for example ERROR)?

Correct, you cannot influence it using settings. You could however implement/override your own Log to implement a custom log method which could log to another level.
