Options¶
Options allow you to modify the contents of the property. Multiple options can be set. They are comma-separated. If conflicting options are specified, always the last option will be in effect (e.g. specifying “uppercase,lowercase” will lead to lowercase conversion of the property value).
The following options are available with this release of the product:
lowercase
All characters in the resulting property extract will be converted to lower case.
uppercase
All characters in the resulting property extract will be converted to upper case.
uxTimeStamp
This is a special switch for date conversions. It only works if the extracted property value is an ISO-like timestamp (YYYY-MM-DD HH:MM:SS). If so, it will be converted to a Unix-like ctime() timestamp. If the extracted property value is not an ISO-like timestamp, no conversion happens.
uxLocalTimeStamp
This is the same as uxTimeStamp, but with local time instead of GMT.
date-rfc3339
This option is for replacing the normal date format with the date format from RFC3339.
date-rfc3164
This option is for replacing the normal date format with the date format from RFC3164.
date-rfc3164strict
Does the same as date-rfc3164 but when the date is below 10, two spaces will be added between Month and day (Which is defined in rfc3164).
escapecc
Control characters* in property are replaced by the sequence ##hex-val##
, where* hex-val is the hexadecimal value of the control character (at least two digits,
may be more).
spacecc
Control characters* in the property are replaced by spaces. This option is most* useful when a message contains control characters (e.g. a Windows Event Log Message) and should be written to a log file.
compressspace
Compresses multiple consecutive space characters into a single one. The result
is a string where all words are separated by just single spaces.
To also compress control characters, use the compressspace and spacecc options
together (e.g.``’%msg:::spacecc,compressspace%’). Please note that space compression happens on the final substring. So if you
use the FromPos and ToPos capabilities the substring is extracted first and
then the space compression applied. For example, you may have the msg string
”1 2”. There are two space between 1 and 2. Thus, the property replacer expression:``%msg:1:3:compressspace%
will lead to "1 "
(‘1’ followed by two spaces). If you intend to receive
"1 2"``('1' followed by one space, followed by '2'), you need to use ``%msg:1:4:compressspace%
or
%msg:1:/2/$:compressspace%
In the second case, the exact length of the uncompressed string is not known, thus a search is used in topos to obtain it. The result is then space-compressed.
compsp
Exactly the same as compressspace, just an abbreviated form for those that like it brief.
csv
For example %variable:::csv%
. This option will create a valid CSV string. For example a string like this:this is a "test"!
becomes this "this is a ""test""!"
where quotes are replaced with double quotes.
cef
Convert string content into valid McAfee CEF Format. This means that =``will be replaced with
=`` and \
will be replaced with \\
. convgermuml
Converts German Umlaut characters to their official replacement sequence (e.g. “ö” –> “oe”)
localtime
Now you can print the Time with localtime format by using``%variable:::localtime%``
nomatchblank
If this is used, the Property Replacer will return an empty string if the frompos or topos is not found.
replacepercent
This option replaces all %
occurrences with a double %%
, which is needed for the property replacer engine in case that a string is reprocessed. This is
needed because the percent sign is a special character for the property
replacer. Once the property is processed, the double``%%``become automatically one``%``. toipv4address
Property string will be converted into IPv4 Address format if possible.
toipv6address
Property string will be converted into IPv6 Address format if possible.
crlftovbar
Does the same as date-rfc3164 but when the date is below 10, two spaces will be added between Month and day (Which is defined in rfc3164).
removecc
Removes all control characters from 0x00 to 0x1F
replacechar
Replaces a single character with another single character.
How ASCII characters are being handeled:
Sample:%msg:$x:$y:replacechar%
Broken down:
%msg:$``<- Tells property replacer that a character is being expected (At the moment only for REPLACECHAR Option). ``x``<- The character to search for ``:
$``<- Tells property replacer that a character is being expected (At the moment only for REPLACECHAR Option). ``y``<- The character to replace with ``:
replacechar%
How special characters are handeled?
Sample: %msg:$\n:$|:replacechar%
%msg:$
<- Tells property replacer that a character is being expected (At the moment only for REPLACECHAR Option). \n
<- The character to search for special character, possible values: t for tab,
n for newline,
v for verticaltab,
f for formfeed,
r for carriage return
for an actual backslash.``:``
$``<- Tells property replacer that a character is being expected (At the moment only for REPLACECHAR Option). ``|``<- The character to replace with ``:
replacechar%
*
= control characters like e.g. carriage return, line feed, tab, …*
Important: All option values are case-sensitive. So “uxTimeStamp” works while “uxtimestamp” is an invalid option!
