Answer 1

You can add a simple IF statement to your LOGON trigger, as such:

USE test;
GO
CREATE TABLE LogonAudit
(
    AuditID INT NOT NULL CONSTRAINT PK_LogonAudit_AuditID 
                PRIMARY KEY CLUSTERED IDENTITY(1,1)
    , UserName NVARCHAR(255)
    , LogonDate DATETIME
    , spid INT NOT NULL
);
GO
GRANT INSERT ON Test.dbo.LogonAudit TO public;
GO
CREATE TRIGGER MyLogonTrigger ON ALL SERVER FOR LOGON
AS 
BEGIN
    IF SUSER_SNAME() <> 'sa'
    INSERT INTO Test.dbo.LogonAudit (UserName, LogonDate, spid) 
            VALUES (SUSER_SNAME(), GETDATE(), @@SPID);
END;
GO
ENABLE TRIGGER MyLogonTrigger ON ALL SERVER;

This will only audit logons for users not named 'sa' by virtue of the line IF SUSER_SNAME() <> 'sa'

Alternatively, if you want to ONLY audit the login of a specific user, you could write the trigger like:

CREATE TRIGGER MyLogonTrigger ON ALL SERVER FOR LOGON
AS 
BEGIN
    IF SUSER_SNAME() = 'SomeUser'
    INSERT INTO Test.dbo.LogonAudit (UserName, LogonDate, spid) 
            VALUES (SUSER_SNAME(), GETDATE(), @@SPID);
END;

This will only record when SomeUser logs into the server.

create table
stats$user_log
(
user_id varchar2(30),
session_id number(8),
host varchar2(30),
last_program varchar2(48),
last_action varchar2(32),
last_module varchar2(32),
logon_day date,
logon_time varchar2(10),
logoff_day date,
logoff_time varchar2(10),
elapsed_minutes number(8)
)
;
create or replace trigger
logon_audit_trigger
AFTER LOGON ON DATABASE
BEGIN
insert into stats$user_log values(
user,
sys_context('USERENV','SESSIONID'),
sys_context('USERENV','HOST'),
null,
null,
null,
sysdate,
to_char(sysdate, 'hh24:mi:ss'),
null,
null,
null
);
END;
