Due to last issues with memcache in Our Server, we need to count bandwidth consumed by local memcached instances (alice one for now).

This can be done by adding needed rules to iptables:

Get INPUT

iptables -I INPUT -p tcp -s 127.0.0.1 --sport 11211 -j ACCEPT

Get OUTPUT

iptables -I OUTPUT -p tcp -d 127.0.0.1 --dport 11211 -j ACCEPT
[[email protected] user]# iptables -I OUTPUT -p tcp -d 127.0.0.1 --dport 11211 -j ACCEPT
[[email protected]@web09 epetrenko]# iptables -I INPUT -p tcp -s 127.0.0.1 --sport 11211 -j ACCEPT
