Hi Matt, your actual setup sounds very reasonable for what you want to do. About the chance of filtering out some traffic, in your case ICMP datagrams, you can use Pre-Tagging.
1. create a new Pre-Tagging file (if you are not already using one for other purposes), say pretag.map; insert into it a line like the following: id=100 ip=<NetFlow agent IP address> filter='ip proto 1' The above line associates the tag '100' to each packet matching the filter 'ip proto 1' (ie. all ICMP packets) coming from your NetFlow agent (in your case, it's the Packeteer Packetshaper). 2. link your Pre-Tagging file into your nfacctd configuration: pre_tag_map: /path/to/pretag.map 3. attach a negative Pre-Tagging filter - matching tag 100 - in your nfacctd configuration: pre_tag_filter[sql_instance_a]: !100 pre_tag_filter[sql_instance_b]: !100 To be even more correct, because one of the two instances should be accounting incoming traffic, you can stick the filter only to that.
