The script functions

Previous  Top  Next

A number of built in functions are available from the Fields object. More functions will be added to future releases to help improve the functionality of the scripting engine.

To use a built in function, simply access the function name prefixed with the Fields object. Pass any parameters needed and the result will be returned.


Built-in functions of the "Fields" object

Function: Opens the specified log file and appends the Data to the end of the file.
Return value: None

This function can be used to log messages to file in your own format.

AutoSplit syntax values can be used in the filename if you want.
To have the filename contain the current hour of the day, use %TimeHH

Example: Filename = "C:\Program files\Syslogd\Logs\TestLog%TimeHH.txt"

Example usage:

Filename = "C:\Program files\Syslogd\Logs\TestLog.txt"
MsgPriority = "Local7.Info"
MsgHostAddress = Fields.VarPeerAddress
' Use the date and time from the current message
MsgDate = Fields.VarDate & " " & Fields.VarTime 
MsgText = "This is a test message from the scripting action"
Data = MsgDate & vbtab & MsgPriority & vbtab & MsgHostAddress & vbtab & MsgText

Call Fields.ActionLogToFile(Filename, Data)

Note: this example requires that Read permission be enabled for "Other fields". This gives the script read access to the VarDate and VarTime variables.

The TabDelimitedMessage must contain 5 tab delimited fields. The contents of each field can be anything you like. The normal display fields are: Date TAB Time TAB Priority TAB Hostname TAB Message.


Example usage:

With Fields
      MsgPriority = ConvertPriorityToText(.VarPriority)
      MsgHostAddress = .VarPeerAddress
      ' Use the date and time from the current message
      MsgDate = .VarDate & " " & .VarTime

Fields.ActionLogToODBC(DSNString, TableName, InsertStatement, Timeout)
Function: Passes the InsertStatement to the database specified by DSNString and TableName. The timeout specifies how many seconds to keep the database connection open when idle.

Return value: For success, an empty string is returned. Otherwise the error is passed back as a string value.

This function can be used to log messages to a database in your own format. The connection to the database is held open internally to the program. This avoids the overhead of creating and breaking the connection each time data is sent. If no further data is sent to the database, once the timeout period has elapsed, the connection will be closed. The next time data needs to be sent, the connection will be reopened.

Example usage:

In the case of this example, a System DSN called "KiwiSyslog" has been created and points to a MS Access database. The SQL insert statement syntax changes slightly depending on the database type being written to. The example here has only been tested on MS Access 97 and 2000.

This example assumes that a table called "Syslogd" has already been created and contains all the required fields.

MyDSN = "DSN=KiwiSyslog;"
MyTable = "Syslogd"
MyFields = "MsgDate,MsgTime,MsgPriority,MsgHostname,MsgText"

' MS Access DB SQL INSERT command example: 
' INSERT INTO Syslogd (MsgDate,MsgTime,MsgPriority,MsgHostname,MsgText) 
' VALUES ('2004-08-08','13:26:26','Local7.Debug','host.company.com',
' 'This is a test message from Kiwi Syslog Daemon')

With Fields
     ' Construct the insert statement
     SQLcmd = "INSERT INTO " & MyTable & " (" & MyFields & ") VALUES (" & _
     Quote(.VarDate) & "," & Quote(.VarTime) & "," & _
     Quote(.ConvertPriorityToText(.VarPriority)) & "," & _
     Quote(.VarPeerAddress) & "," & Quote(.VarCleanMessageText) & ")"
     ' Log the data to database using DSN, Table, SQLcmd and Timeout of 30 seconds
     .VarCustom01 = .ActionLogToODBC(MyDSN, MyTable, SQLcmd, 30)
     ' VarCustom01 now holds the return value from the function.
End with

Function Quote(Data)
    ' Replace all occurrences of ' with '' to escape existing quotes
    ' Wrap data with single quotes    
    Quote = "'" & Replace(Data, "'", "''") & "'"
End Function

Note: This example requires that Read permission is enabled for "Other fields". This gives the script read access to the .VarDate and .VarTime variables.

Note: There are more example scripts installed in the \Scripts sub folder.
