Problem conclusion

  • The issue has been fixed indirectly in Fix Pack 3. Please
    upgrade to Fix Pack 3
    The configuration change needed to allow long walks to succeed.
    The m_HelperReqTimeout field of the SnmpHelper.SnmpHelperConfig
    table defines how long an snmp request can take to return before
    it will time out. For walks that take longer than 20mins, this
    field will need to be increased.
    
    In DiscoHelperServerSchema.cfg:
    
    insert into SnmpHelper.SnmpHelperConfig
    (
            m_HelperDbTimeout,
            m_HelperReqTimeout,
            m_HelperStartupTimeout,
            m_HelperDoWeQuery,
    //      m_HelperDebugLevel,
    //      m_HelperMessageLevel,
    //      m_HelperLogFile,
            m_HelperDoWeStore
    )
    values
    (
            259200, // 3 days
            2400,  // eg increase from 20 mins to 40 mins
            90,             // 90 seconds
            0,              // No, we don't query database.
    //      4,              // debug level 4
    //  'info',     // messagelevel of 'info'
    //      "$NCHOME/log/precision/snmphelper.log", // file name for
    the log file
            0               // No, we we don't store data.
