How to drop incoming deny logs from firewall logs

I am trying to filter out all inbound deny syslog that the firewall is sending I have a props.conf like this [srx_log] TRANSFORMS-srxDrop = srxDropDeny I have transforms.conf like this ############################## # Drop Firewall inbound deny ############################### [srxDropDeny] REGEX = (RT\_FLOW\_SESSION\_DENY.+source-zone-name\=\"untrust\") DEST_KEY = queue FORMAT = nullQueue I can see that the logs are not being dopped. How do I ..... Or where do I look to see why this is not working. Is there an internal log that tracks the transforms and props activity? is there a log file that tracks if or if not a filter is working?
