To capture XML data about LOGON events for use inside logon triggers, use the EVENTDATA function. The LOGON event returns the following event data schema:
<EVENT_INSTANCE>
<EventType>event_type</EventType>
<PostTime>post_time</PostTime>
<SPID>spid</SPID>
<ServerName>server_name</ServerName>
<LoginName>login_name</LoginName>
<LoginType>login_type</LoginType>
<SID>sid</SID>
<ClientHost>client_host</ClientHost>
<IsPooled>is_pooled</IsPooled>
</EVENT_INSTANCE>
<EventType>
Contains LOGON.
<PostTime>
Contains the time when a session is requested to be established.
<SID>
Contains the base 64-encoded binary stream of the security identification number (SID) for the specified login name.
<ClientHost>
Contains the host name of the client from where the connection is made. The value is '<local_machine>' if the client and server name are the same. Otherwise, the value is the IP address of the client.
<IsPooled>
Is 1 if the connection is reused by using connection pooling. Otherwise, the value is 0.
