Girtsd's questions

I have taken upon myself the configuration of an ipv6 network in an enterprise lan. There is a single VLAN for all the hosts in the LAN. I am using pfsense 2.3.4 software.

I now have to figure out the address distribution in the LAN. The addresses should not allow identifying any of the hosts from the global network, so there are 2 options. NATv6 with local addresses or global addresses with address rotating, but I`ve read about NATv6 being a bad choice. I could just set up address rotating with global addresses, but that would keep me from creating IP address based firewall rules, since the addresses would change all the time.

Is there a way I could assign an IPv6 address range to each of the hosts to rotate their addresses within that range, so I could still write firewall rules for each of these ranges (instead of static addresses) and hide (to some extent) the public addresses of hosts from global viewers? And is this doable in pfsense?

I could also have just made a VLAN for each different role in the office and rotate global addresses on a per role basis and create firewall rules on a per role basis, but that is not an option.

My first post so be gentle please! So I have an installation of graphite up and running on Ubuntu 16.04 server. (version 0.10)

I am sending in metrics and everything works fine, but I am sending in multiple timestamps at once. As in I am sending in data once per minute with per 10s timestamps. Every minute new data comes in. It can happen, that a key with a corresponding timestamp (same as before) is resent a minute later. So the new value is being saved and last one lost, because of the way graphite works. So I put a carbon-aggregator in front of carbon-cache thinking it will aggregate the values per timestamp. It does not. It aggregates all values received in a time interval ignoring the timestamps.

I found that statsd has the same functionality. What I want is for the aggregator to aggregate values per timestamp. As in keep data for lets say 1 minute and see if a datapoint for the same key and timestamp is received. If so sum them. If no such data came, forward the original data to carbon-cache.

Is there a way to do this with graphite or statsd, or do I have to write my own little buffer in front of carbon-cache (instead of carbon-aggregator), that does this? It could be a linked list of self made structures in C resulting in about 150 lines of code, but would take precious time.

Someone has definitely had the same problem, but has anyone found a solution?

Bump: has noone really encountered this issue?

Thanks in advance!
