Hi, Akhina. Seems like your logging verbosity level is at defaults? Or have you tried to set "loggingLevel" property to "DEBUG" or "TRACE" for oxAuth on "JSON configuration" page? This should provide you mode details.

Hi Aliaksandr, I tried changing the log level and I am getting the below messages from where I can get the client failure details.

Is there any alternate solution for this. Thanks, Akhina S Kumar

Could you try to formulate your requirements more specifically, like which of the log entries you get on TRACE level your actually need, which ones you would like to see, but not getting at the moment even with TRACE level etc - then I'll relay the question to oxAuth dev and may be he'll share some thoughts. Also please elaborate on the possible memory issues you mention, we need to understand that usecase better. By the way, have you also checked oxAuth audit log localed in the same directory? May be it will be of some use too?

Hi Aliaksandr, My use case is to get a proper report on the number of client autnetication (successful and failure). For this I have analyzed the oxauth.log and I was able to find the only the client authentication successful entries. There was nothing for client authentication failed. 2023-05-11 00:50:33,943 INFO [qtp934275857-155096] [org.gluu.oxauth.auth.Authenticator] (Authenticator.java:278) - Authentication success for Client: '########################' And also have lot of user authentication failure messages. It doesn't have any information on whether its a normal user or a client associated user. To confirm this I changed the log level to TRACE , which showed me more information about the user authentication failure and I found few entries showing the failure is associated with certain clients. 2023-05-18 10:58:29,333 TRACE [qtp1686100174-1623413] [org.gluu.service.BaseCacheService] (BaseCacheService.java:84) - Put data, key 'oxId=7009a79e-2102-4498-bb2c-c6c840e7e478,ou=sessions,o=gluu': 'SessionId {dn='oxId=7009a79e-2102-4498-bb2c-c6c840e7e478,ou=sessions,o=gluu', id='7009a79e-2102-4498-bb2c-c6c840e7e478', outsideSid='fa42a8e9-cae6-4ad0-b808-b0ed3cf953c4', lastUsedAt=Thu May 18 10:58:29 UTC 2023, userDn='null', authenticationTime=Thu May 18 10:58:14 UTC 2023, state=unauthenticated, expirationDate=Thu May 18 11:58:14 UTC 2023, sessionState='e46c9b27b11e42c7535ba636da2cd8178e0141a909887d6cae2f102f335b35b7.d7aa7add-99bd-44ee-b92c-470e54c80564', permissionGranted=null, isJwt=false, jwt=null, permissionGrantedMap=SessionIdAccessMap{permissionGranted={dbbc9aa7-90b3-455a-8244-1039b99d4c01=false}}, sessionAttributes={auth_step=1, acr=Azure-O365-Integration, remote_ip=198.151.217.183, auth_external_attributes=null, opbs=c76fef9a-92f7-4670-981f-87d64495fc22, scope=openid user_name profile permission email, response_type=code, redirect_uri=################################, state=VyEtsF6zEqEWyAR, nonce=N646604c46c4c4, client_id=####################, response_mode=form_post}, persisted=true}' 2023-05-18 10:58:29,333 INFO [qtp1686100174-1623413] [org.gluu.oxauth.auth.Authenticator] (Authenticator.java:225) - Authentication failed for 'akhina.kumar@sennovate.com' But keeping the log level to TRACE will take more disk space. Also I don't find any entries related to client authentication failure from audit logs. Thanks, Akhina S Kumar

Hi Team, Is this information sufficient or you need any further details. Thanks, Akhina S Kumar

Hi Team, Any update on this issue. Thanks, Akhina S Kumar

Hi, Akhina. I think your question is clear. The problem is Gluu 4.x is as of recently behind paywall, it's no longer offered free of charge - neither the support for it. Sorry for that. From now on, if you are after the free open-source version of our main product, you should go after [Janssen](https://docs.jans.io/v1.0.13/). That's the main focus of development right now, and Gluu CE is considered a legacy software now. @Mobarak Hosen.Shakil , could you please investigate quickly whether or not Janssen can offer customizable logging features like Akhina was talking about, and share the results in the ticket?

Hi, Akhina. Sorry about all the chaos - we're in the middle of transition over here.. I stay corrected - as of now this Support Board is only for paying customer's access. No community tickets will be served here. As Janssen is the new free of charge offer, all discussions related to it must go to its own [discussion boards](https://github.com/JanssenProject/jans/discussions). I'll be closing this ticket now.
