1. Netdisco starman process memory leak? (Pavel Skovajsa)
2. Special Report needed aka "IP-Inventory with extra columns"
(Sebastian R?sch)
--- Begin Message ---
Hello,
I do not know too much about memory leaks, but I found some bad looking
message on our dedicated Netdisco server below. It is a Ubuntu Server
12.04LTS VM with 16Gbps RAM.
Can somebody help me out troubleshooting this?

Hi all,
I´ve got a little problem....I need a report from netdisco, which is not
available so far. If the "Ip Inventory" Report would be extend for the columns
device and port, that would exactly meet my requirements very well. But I don´t
know how to do that....
As I was not able to get the query working in the webinterface I tried to
execute a query in the shell.... I was trying to combine the following select
statement with a join. So I started with executing them for their own. But the
select doesn´t work, the join statement works, but I would like to limit the
output of it to nodes from a specific subnet.... I thought this could be done
in a way like described here:
http://stackoverflow.com/questions/12970187/nested-select-statement-with-left-join
bin/netdisco-do psql -e "COPY (SELECT * FROM node_ip WHERE node_ip.ip LIKE
'%10.200.%') TO STDOUT WITH CSV HEADER"
bin/netdisco-do psql -e "COPY (SELECT * FROM node INNER JOIN node_ip ON
node.mac = node_ip.mac) TO STDOUT WITH CSV HEADER"
Any ideas how I can get this working? Of course I would prefer to get it
running as a report or the best way would be to modify the IP Inventory tool....
Regards,
Sebastian
