Recently NTT investigated how to best monitor the visibility of our 
own and our subsidiaries’ IP resources in the BGP Default-Free Zone. 
We were specifically looking how to get near real-time alerts funneled 
into an actionable pipeline for our NOC & Operations department when 
BGP hijacks happen.

Previously we relied on a commercial “BGP Monitoring as a Service” 
offering, but with the advent of RIPE NCC’s “RIS Live” streaming API 
[1] we saw greater potential for a self-hosted approach designed 
specifically for custom integrations with various business processes. 
We decided to write our own tool “BGPalerter” and share the source 
code with the Internet community.

BGPalerter allows operators to specify in great detail how to 
distribute meaningful information from the firehose from various BGP 
data sources (we call them “connectors”), through data processors 
(called “monitors”), finally outputted through “reports” into whatever 
mechanism is appropriate (Slack, IRC, email, or a call to your 
ticketing system’s API).

The source code is available on Github, under a liberal open source 
license to foster community collaboration:

If you wish to contribute to the project, please use Github’s “issues” 
or “pull request” features. Any help is welcome! We’d love suggestions 
for new features, updates to the documentation, help with setting up a 
CI regression testing pipeline, or packaging for common platforms.

Kind regards,

Job & Massimo


Excellent, now I don't have to write it myself. Looking forward to 
testing. Thanks for sharing the fruits of your labor with the community.

Kind regards,

Re: Service Provider NetFlow Collectors

We use kentik and we're very happy. Works great, tons of new features 
coming along all the time. Going to start looking into ddos detection 
and mitigation soon.

Would recommend.

Kind regards,

Hi Nanog….

We are mainly looking to analyze the netflow data. Bonus if it does

Re: YANG daemeon for Linux

What you want is probably sysrepo

Yes Rob, i’d like to do what you described: use netconf and yang to
provision the quagga BGP implementation.

Can you describe work arounds? If any.

Can i convert a bgp yang model to json/yaml and have some other app consume

Could you define "render"?  If you're looking to take a YANG model (which
one?) and configure Linux kernel networking features with it, I can't
recall having seen something that does this. I have been working on a side
project (which I'm hoping to bring to a hackathon) to take Linux networking
and map it to OpenConfig - but this is maexceptionally embryonic.

If you're looking for ways to manipulate data instances for YANG-modelled
schemas on Linux, here are some options (full disclosure: I lead the
development of two of them):

- ygot - produces Go structs, or Protobufs that correspond to a YANG
model -
- pyangbind - produces Python classes that correspond to a YANG model -
- ydk (Cisco) - produces Python and C++ APIs, more centred around device
interaction (

Re: SNMP "bridging"/proxy?

2016-05-23 Thread Eric Lindsjö

Hi Nathan,

You should probably write a cacti script to ingest the data instead of 
this SNMP proxy thing. Writing scripts to ingest data into cacti is 
simple, you just need to output the values you want in key: value format 
and then do some clicking in cacti. There are good docs for how to do this.

Hey, thanks guys!  I had never really looked that deeply into Net-SNMP and had 
only ever installed it either to use as a client (snmpget/snmpwalk) or a basic 
agent w/ standard MIBs for the host it's running on, so I was unaware of its 
extensibility.  And it even looks like it ships with a Perl module.  That 
sounds like a perfect solution; thanks for pointing me in the right direction.
