  • 1.  STAP Verification failure

    Posted Tue February 22, 2022 07:29 AM
    Hi,
    I have IBM guardium standalone version
    Build: 11.0
    Release: 11.4.0_r111112_v11_4_1-el79-20210904_1954
    DB server is Oracle linux 8.5
    Db is oracle 12c
    Have installed GIM and configured STAP
    Got the following error: PROBLEM : S-TAP verification completed . The S-TAP is not monitoring network database trafic
    1  failed checks :
    -checks : detected a client IP/Mask (::/0) that  may prevent s-tap from processing the verification request
    - action: check the online help for the definition of Client IP/Masks

    5 successfull checks:
    - sniffer is running
    - S-TAP Host x.y.z.t is reachable
    - There are no exclude IP masks defined that could prevent the verification request from being captured
    - S-TAP Host x.y.z.t is active
    - Load balancing is not impacting verification. Parameter 'PARTICIPATE_IN_LOAD_BALANCING is set to 0

    Thanks for Your help/support .
    Best regards

    HI,

    Just check whether you are able to log the db commands once installing monitoring policy.
    If everything is fine, ignore STAP verification. It doesn't a matter.

    HI,

    Upgrade to latest version of GIM & STAP with below s-tap parameters.

    For windows:
    STAP_Enabled - 1
    SQL_Guard_IP - 1.1.1.1 (1.1.1.1 is the collector ip for instance).

    For Linux:
    STAP_ENABLED - 1
    KTAP_ENABLED - 1
    KTAP_LIVE_UPDATE - Y
    KTAP_ALLOW_MODULE_COMBOS - Y
    SQL_Guard_IP - 1.1.1.1 (1.1.1.1 is the collector ip for instance).

    Thanks,
    Panendar Rao.C

    Does LIVE_UPDATE mean Guardium and/or DB server need to connect to internet ?

    Hi @Tsilavo Andriamialison:

    LIVE_UPDATE does not require access to the internet. It's simply a flag that enables K-TAP update without requiring a server reboot. Default=Y. Linux-UNIX: S-TAP GIM installation parameters - IBM Documentation

    Hi , 
    After upgrade , we go the following error  now :
    LOG_CONF_ERR
    MSG(819) MODULE(1) SEV(6) COUNT(1) CONF_ERROR: IPC reader failed to initialize Opening pseudo device /dev/guard_ktap No such file or directory,will check if ktap is loaded every 15 minutes, ktap_install is set to 0, no data will be captured from KTAP

    Do you have any advice ?
    Thanks

    Hi @Tsilavo Andriamialison,

    It is ​the behavior of the S-TAP to change the ktap_install parameter to 0 when the K-TAP doesn't contain a module that matches your kernel version, so, the first step I would take is to determine if the S-TAP bundle you are using has a compatible K-TAP. 

    Here's a link to the knowledge article on it: Linux-UNIX: Requesting a K-TAP module - IBM Documentation

    We solved the issue by reinstalling all module and bundle : GUIM , STAP , ...
    However, here is another issue related to the same Standalone Guardium appliance :
    We have another DB server with the following :
    DB= postgresql 14
    All KTAP and STAP status is OK now .
    What is the meaning of the Traffic flagged not green as per the screenshot below ? : we got the same with postgresql 10.17 :
