Hello list,

I need some clarification. I am new at accounting with netflow and pmacct.
I have a LAN topology. The number of LAN users is about 300 (and counting).

Here is my topology:

ISProuter|---|FW|---|coreswitch|---|VLANs/Customer

I have a netflow capable Cisco 4506 swtich. I this device is about to export
the netflow data to my collector (pmacct/nfacctd).
Settings on the switch:

ip flow-capture vlan-id
ip flow-capture mac-addresses
ip flow ingress infer-fields
ip flow ingress layer2-switched
ip flow-export source Vlan10
ip flow-export version 5
ip flow-export destination 1.3.2.35 2055
ip route-cache flow infer-fields

nfacctd.conf:

daemonize: true
plugins: mysql
aggregate: src_host,dst_host,src_port,dst_port,proto
nfacctd_port: 2055
sql_refresh_time: 120
sql_history: 1M
sql_table_version: 5
sql_table: acct_v5_%Y_%m
sql_table_schema: /etc/nfacctd.schema
sql_db: pmacct
sql_user: pmacct
sql_passwd: xxxxxxxxxxxx
sql_num_protos: true

I need two things:
a. The ability to create statistics based on source_ip or destination_ip.
b. The ability to create summarized statistics per vlan or subnetwork.

My questions are:
1. the settings above what I have in nfacctd.conf are appropriate for what I
need?
2. Is there a better way do get what I need?
3. I plan to rotate the database where I collect data monthly (create a new
database at the begining of every month based on nfacctd.schema). Is this a
proper way?
4. Even cisco sends vlan info it does not show up in the database, any idea?

A line in the database looks like this:

+----------+----------+-------------+-------------+------+-----------------+-----------------+----------+----------+----------+-----+---------+-----------+-------+---------------------+---------------------+
| agent_id | class_id | mac_src     | mac_dst     | vlan | ip_src          |
ip_dst          | src_port | dst_port | ip_proto | tos | packets | bytes
| flows | stamp_inserted      | stamp_updated       |
+----------+----------+-------------+-------------+------+-----------------+-----------------+----------+----------+----------+-----+---------+-----------+-------+---------------------+---------------------+

Thanks for your help in advance,
