<br>
You can use template functions in patterndb [1].<br>
The idea is to add a value to the matched message, which contains the result<br>
of a template function. You could for instance use the "if" function:<br>
<br>
<values><br>
<value name="svc">$(if ("${port}" == "22") "ssh" "telnet")</value><br>
</values><br>
<br>
If you need anything more complex, and if you are using the 3.7.x series,<br>
you could even use a python script using the "python" template function.<br>
<br>
Cheers<br>
