comment Sending bulkmail from different server?
Absolutely. From my experience, and I'm not trying to sell their services, not only does sendgrid get good results, but you can't underestimate how much they know about spamming^Wbulk E-mail and will guide you in your DNS configuration. The work involved to please all major E-mail providers is also quite significant. I assume all serious bulk E-mail services will similarly get a lot out of your plate.

comment ULogd2.x - Documents - IPFIX data generation
[follow up] I would use libnetfilter_conntrack in 2 separate processes: 1. to grab all the events I'm interested into (multiple contexts to allow for complex filtering logic as their bsf usage is rather limited) and publish them on a zeromq socket, reencoded in msgpack (obviously with network endianness). 2. to periodically go through all connections and publish a snappy-compressed msgpacked list. That way I can have a good view of the current connections on a host even if the other process dies, or connections are started before it, and get traffic counters reasonably often.

comment ULogd2.x - Documents - IPFIX data generation
Unfortunately it'd have to be more complete then go through a code review before I can publish it. I don't target any IPFIX support on the machines but would rather take care of that centrally as I want a minimal communication layer on the hosts that can adapt to different types of information. I'll do the deduplication given I'll see many connections multiple times (from both machines when within my infrastructure, through 1 firewall in some contexts, through 2 firewalls for many cross-DC connections), and IPFIX tooling can't be as precise as some information will be lost in the translation.

comment Is there an way to get the top level classes included in a puppet node?
You can't have a command running on the client giving you the information, as the external node classifier and manifests are only known by the puppetmaster and never exposed to the puppet agent (only the compiled manifests are). So you'll need a trick like mine in your manifests, which is compiled by the puppetmaster then provided to the agent.

comment ULogd2.x - Documents - IPFIX data generation
I have a project to collect nf_conntrack_netlink data and aggregate it centrally, but if an efficient solution based on ulogd exists I'd love to hear about it!

OK, then it looks like a kernel bug. Can we have uname -a?
