persistent class %SYS.Audit
extends %Persistent, %SYSTEM.Help, %XML.Adaptor
The Cache auditing system allows the user to capture events
which occur on the system, and log them to an audit file.
When running SQL queries on the audit log, it is helpful to use the UTCTimestamp
in the WHERE clause to speed up the query, and minimize the amount of data
which is returned. For example:
SELECT SystemID,AuditIndex,UTCTimeStamp,EventSource,EventType,Event,Pid,CSPSessionID,Username,Description
FROM Audit
WHERE UTCTimeStamp BETWEEN :UTCBeginDateTime AND :UTCEndDateTime
ORDER BY UTCTimeStamp DESC, SystemID DESC, AuditIndex DESC)
The UTCTimeStamp is the UTC time in ODBC format. To convert a local $H time to this format use
the following:
s x=##Class(%SYS.Audit).ConvertLocalHToUTC($H)
The UTCTimeStamp which is returned as part of the record, can be converted to local time
with the following:
s x=##Class(%SYS.Audit).ConvertUTCToLocal(UTCTimeStamp)
• property AuditIndex
as %BigInt;
• property CSPSessionID
as %String(MAXLEN=16);
Session ID of the process if a CSP process.
• property ClientExecutableName
as %String(MAXLEN=128);
Executable name on the client machine.
• property ClientIPAddress
as %String(MAXLEN=128);
IP address of the client.
• property Description
as %SYS.AuditString(MAXLEN=128);
Description of the audit event.
Control characters less than $c(32) are not allowed in this data except
for CR,LF, and tab.
• property Event
as %String(MAXLEN=64);
Name of the audit event.
• property EventData
as %SYS.AuditString(MAXLEN=16384);
EventData -- arbitrary data associated with this event.
Control characters less than $c(32) are not allowed in this data except
for CR,LF, and tab.
• property EventSource
as %String(MAXLEN=64);
Event Source (system events all have "%System" here).
• property EventType
as %String(MAXLEN=64);
EventType.
• property GroupName
as %String(MAXLEN=64);
Group of the audit event.
• property JobId
as %String(MAXLEN=16);

• property Namespace
as %String(MAXLEN=128);

• property OSUsername
as %String(MAXLEN=16);
Operating system username of process.
Username given to the process by the operating system when the process
is created. When displayed, it is truncated to 16 characters. Note that the real O/S
username is only returned when connecting to UNIX or VMS systems; For Windows, it
will return the O/S username for a console process, but for telnet it will return
the $USERNAME of the process. For client connections, it contains the O/S username
of the client.
• property Pid
as %String(MAXLEN=16);
Process ID.
Note that on VMS system, the Hex pid is stored internally as a decimal value, i.e. $zh(pid).

• property RoutineSpec
as %String(MAXLEN=128);

• property Status
as %Status [ InitialExpression = 1 ];
Any %Status variable passed into the call.
• property SystemID
as %String(MAXLEN=128);
SystemName:ConfigurationName of where the event was generated.
This is useful when merging separate audit streams from different systems.
• property UTCTimeStamp
as %String(MAXLEN=64);
UTC $ZTIMESTAMP value when the audit event occurred.
• property UserInfo
as %String(MAXLEN=64);
User info field
• property Username
as %SYS.AuditString(MAXLEN=128);
Username from $Username that was active when audit event occurred.
• classmethod Convert(ByRef Count As %Integer, Force As %Integer = 1)
as %Status
Convert from ^CacheAuditD(System,ID) to ^CacheAuditD(UTCTimeStamp,System,ID).
The format changed between 2008.2 and 2009.1.
Parameters:
Count (byref) - Returned count of number of audit records converted.
Force - 0/1 - Force reading and converting of all audit records even if
version already = 2009.1.
Note: This function automatically will get called on audit databases when they are
referenced the first time after an upgrade to 2009.1 or later. However, if data from
older systems (pre-2009.1) are merged into the system without using one of the audit
utilities, then the data being imported may not be indexed correctly for the system
to see it. If this is the case, call the Convert method in that namespace, and pass the
Force parameter = 1.
• classmethod ConvertLocalHToUTC(LocalH As %String)
as %String
Convert the local $H time to an ODBC format string in UTC.
When using SQL, use this function to convert a local time in $h to UTC time to
