app-agent-config.xml - use of regex to mask segment data #966

Hi,

I'm trying to use match-pattern - regex but it does not work properly. E.g.:

        <sensitive-url-filter delimiter="/"
                              segment="3,4,5,6"
                              match-filter="REGEX"
                              match-pattern=":"
                              param-pattern="myParam|myAnotherParam"/>

this should mask selected segments that contains : but it masks everything. If I do match-pattern="=" it works as expected. Another examples that does not work (they mask everything): match-pattern="[^a-z¦-]+" match-pattern="\x3A"

Is there any subset of regular expression that it's allowed to use here ? Thanks

I don't believe the buildpack is consuming that file, it's just being passed through to the AppDynamics agent. You would need to ask the vendor what they support in that configuration file.
