  • cvfwd.log massive output in the logs of each job
    Posted: 12-05-2019, 4:35 AM

    Hi All,

    Since we upgraded to SP16 cvfwd.log is flooding the logs of each job in the backup infrastructure.

    It is confusing because when you try to analyze any failing job, you have to scroll down 5 ~ 10 pages with 3000 rols each, and all of this pages are:

     

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    Machine : Commcell
    File    : cvfwd.log
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

    We already raised case to the support, but they informed that this could not be changed.

    I am asking here, if there is someone who have same behavior in the logs, and what is your way deal with this.

    Thank you in advance for your attention!

    Many of the log files include the PID, Thread ID, Time Stamp and CV Job ID.  The Commvault Firewall Daemon does not record the Job ID, so what you are seeing is all the cvfwd connections made during a single job.

    Perhaps as an alternative, if you are troubleshooting a job run on a Windows Client - then GxTail is an excellent tool if you have access to the client desktop.  http://documentation.commvault.com/commvault/v11/article?p=49881.htm

    If you want to know which Client or Server process will write it's log into, then this article can help https://documentation.commvault.com/commvault/v11_sp17/article?p=5616.htm

    Hi,

    Thank you for your reply.

    Yes, i am aware of the gxtail tool and i am using it from time to time.

    The problem is that when you have pending job in the job controller, and click view logs, you have to scroll alot of in order to locate desire log you are looking for.

    So, this is my question, how to dial with this.

    Thanks.

    View the logs for the failing process and then check the time frame listed in cvfwd if there is anything there to even look at.

    From what I can see the CommServe cvfwd logs are being populated with client guid entries that don't relate to the job, and given that in his instance there are 10's of thousands of cvfwd entries returned - it is cumbersome to review from the view logs feature.

    What's the issue you are troubleshooting that requires digging in the cvfwd log?

    I don't believe the author in this instance is wanting to look through cvfwd. When you right click on an a job and view logs for the job id from the CommCell Console Job Controller, the application will concatenate all the log files into a 10000 line textbox. If the returned content is several 10's of thousand the view log by jobid feature then you need to manually page through. In the author's case, the view logs by jobid would be easier if cvfwd just returned information that was important to troubleshooting the client. Or if that is too complex to parse, perhaps CV can include cvfwd as an optional output? Or better still, have the feature return just the FwConfig.txt & FwConfigLocal.txt files rather having to wade through the cvfwd? ;)

    You could create a Customer Modification Request through Support or your Account Rep for this situation.

    This is fixed to not show the entries from this file when the user does View Logs by JobId in V11 SP16 via HotFix-1990.

     

    Thanks,

    Hi Bheemesh, SP16 HPK28 is the latest available Hotfix Pack and 1990 is not present.  I guess it is coming in HPK29+?

    Im glad to see this post because I took the same concern to commvault back in september and I was told that this was normal but before SP16 I was not being bombed with that many messages. Up to this day, running SP17 still see the same logs.

    Hi,

     

    This HOT Fix should be part of HPK30.

     

    Thanks,
