Details

/etc/collectd.d/common.conf contains on *all* collectd clients:

LoadPlugin tcpconns
<Plugin "tcpconns">
  ListeningPorts false
  LocalPort "22"
#  RemotePort "22"
</Plugin>

Not certain of it's origin, but it has a huge performance impact on hosts with lots of TCP connections, (i.e. ZLBs).

Basically, the plugin is inspecting *all* tcp connections in a fairly tight loop, trying to filter the connections its looking for.

For now, from IRC, I will disable that check globally, and it can be re-enabled in a modular fashion for only the hosts that need it. jumphosts, maybe?
