path-network/logstash-codec-sflow: Logstash codec plugin to decrypt sflow

Logstash Codec SFlow Plugin

Description

Logstash codec plugin to decode sflow codec.

This codec manage flow sample, counter flow, expanded flow sample and expanded counter flow

For the (expanded) flow sample it is able to decode Ethernet, 802.1Q VLAN, IPv4, UDP and TCP header

For the (expanded) counter flow it is able to decode some records of type:

Generic Interface

Ethernet Interface

VLAN

Processor Information

HTTP

LAG

TO DO

Currently this plugin does not manage all sflow counter and is not able to decode all kind of protocols. If needed you can aks for some to be added. Please provide a pcap file containing the sflow events of the counter/protocol to add in order to be able to implement it.

Tune reported fields

By default all those fields are removed from the emitted event:

%w(sflow_version header_size ip_header_length ip_dscp ip_ecn ip_total_length ip_identification ip_flags ip_fragment_offset ip_ttl ip_checksum ip_options tcp_seq_number tcp_ack_number tcp_header_length tcp_reserved tcp_is_nonce tcp_is_cwr tcp_is_ecn_echo tcp_is_urgent tcp_is_ack tcp_is_push tcp_is_reset tcp_is_syn tcp_is_fin tcp_window_size tcp_checksum tcp_urgent_pointer tcp_options vlan_cfi sequence_number flow_sequence_number vlan_type udp_length udp_checksum)

You can tune the list of removed fields by setting this parameter to the sflow codec optional_removed_field

frame_length_times_sampling_rate output field on (expanded) flow sample

This field is the length of the frame times the sampling rate. It permits to approximate the number of bits send/receive on an interface/socket.

You must first ensure to have well configured the sampling rate to have an accurate output metric (See: http://blog.sflow.com/2009/06/sampling-rates.html)

Human Readable Protocol

In order to translate protocols value to a human readable protocol, you can use the logstash-filter-translate plugin

filter { translate { field => protocol dictionary => [ “1”, “ETHERNET”, “11”, “IP” ] fallback => “UNKNOWN” destination => protocol override => true } translate { field => eth_type dictionary => [ “2048”, “IP”, “33024”, “802.1Q VLAN” ] fallback => “UNKNOWN” destination => eth_type override => true } translate { field => vlan_type dictionary => [ “2048”, “IP” ] fallback => “UNKNOWN” destination => vlan_type override => true } translate { field => ip_protocol dictionary => [ “6”, “TCP”, “17”, “UDP”, “50”, “Encapsulating Security Payload” ] fallback => “UNKNOWN” destination => ip_protocol override => true } }

This is a plugin for Logstash.

It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.

Documentation

Logstash provides infrastructure to automatically generate documentation for this plugin. We use the asciidoc format to write documentation so any comments in the source code will be first converted into asciidoc and then into html. All plugin documentation are placed under one central location.

For formatting code or config example, you can use the asciidoc [source,ruby] directive

directive For more asciidoc formatting tips, see the excellent reference here https://github.com/elastic/docs#asciidoc-guide

Developing

1. Plugin Developement and Testing

Code

To get started, you’ll need JRuby with the Bundler gem installed.

Create a new plugin or clone and existing from the GitHub logstash-plugins organization.

Install dependencies

bundle install

Test

bundle exec rspec

The Logstash code required to run the tests/specs is specified in the Gemfile by the line similar to:

gem “logstash” , :github => “elasticsearch/logstash” , :branch => “1.5”

To test against another version or a local Logstash, edit the Gemfile to specify an alternative location, for example:

gem “logstash” , :github => “elasticsearch/logstash” , :ref => “master”

gem “logstash” , :path => “/your/local/logstash”

Then update your dependencies and run your tests:

bundle install bundle exec rspec

2. Running your unpublished Plugin in Logstash

2.1 Run in a local Logstash clone

Edit Logstash tools/Gemfile and add the local plugin path, for example:

gem “logstash-codec-sflow” , :path => “/your/local/logstash-codec-sflow”

Update Logstash dependencies

rake vendor:gems

Run Logstash with your plugin

bin/logstash -e ‘ input { udp { port => 6343 codec => sflow }} ‘

At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.

2.2 Run in an installed Logstash

Build your plugin gem

gem build logstash-codec-sflow.gemspec

Install the plugin from the Logstash home

bin/plugin install /your/local/plugin/logstash-codec-sflow.gem

Start Logstash and proceed to test the plugin

Contributing

All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.

Programming is not a required skill. Whatever you’ve seen about open source and maintainers or community members saying “send patches or die” – you will not see that here.

It is more important to me that you are able to contribute.

Open Source Flow Collecting with Elastic, Logstash, and Kibana

Today, most open source network flow tools lack a flexible and easy to use interface. Using Logstash’s built-in netflow codec, Kibana’s great looking and powerful web interface, and the flexibility of Elastic, you can build a tool that rivals commercial flow-collecting products.

Kibana – Analyzing data

Discover

Discover is the main screen in Kibana and a good place to test and build queries. You can customize the columns and time displayed, look at the top n of each field in the left column, and open the flow record to see its complete details. From here you can save searches or create queries and pin them to use later in visualizations.

Visualize

There are many ways to present your data in Kibana. The top three for us are line charts, pie charts, and map views. There are a few few other visualizations as well.

Line charts are great for displaying bytes per second (bps) or packets per second (pps) over time. The line graph below shows total bps for the matched country (Poland) over the past 5 days. When you choose per-second aggregation, Kibana may change your aggregate values, but it still does the math to give you the correct per second value.

Pie charts are well suited for showing data relative to the entire result set. There can even be multilayered data on the chart. The inner layer of the pie chart below shows relative traffic per country. The outer layer represents the different WordPress.com data centers where the traffic was received.

The map is useful to see how anycast routing is performing. In the map below, the query matches Sydney data center for traffic over the past 24 hours. You can see a few spots in North America. In this case, the cause is international networks that don’t have correct geolocation info on their IP addresses. The map data is only as good as the geolocation source.

There are many other visualization options and the only limit is your imagination!

Bytes per second to Poland Traffic by country Anycast traffic in Sydney

One real-world example of the visualizations working together is to identify networks that aren’t routing traffic to the nearest data center. In the past, we’ve found networks peering with foreign route servers and preferring those routes instead of using much closer data centers. Using the Kibana map, we can select a problematic geographical area and create a filter focused on just the specific sources. The query is then used in a pie chart, showing you the top source ASNs and some example source/destination IPs. Filtering further, you can create a line chart to determine how many Mbps could potentially move to another, closer, PoP. This is just one of nearly limitless use cases of collecting and analyzing your netflow data with ELK.

Dashboard

It is fun and useful to set up different views in your network by having multiple complimenting charts on your screen. We’ve setup a Denial of Service dashboard that tracks spikes in suspicious traffic, such as DNS, SYN floods, NTP, or any other UDP spikes.

In this example there was a spike in UDP traffic. We highlighted the area to zoom in on that period in time. Kibana then redraws the results of all of the charts in the dashboard for that time period which allows us to see details of the traffic spike. We see what routers and interfaces that received the majority of the traffic on the pie chart. The inner layer of the pie chart represents a router, the mid area represents attached interfaces to each router and the outer area of the pie chart represents UDP vs TCP on a given interface. We can see the blue, representing UDP, appear on the dashboard below.

Logstash – Collecting the data and help make it useful

Config

The configuration for Logstash can be as simple as just adding an input of the netflow codec and an output of Elastic. Logstash has many powerful filters that can be combined with conditional statements to add value and readability to your data. Here are a few examples of filters in action:

# Private ASN is actually AS2635 if [netflow][dst_as] < "65535" and [netflow][dst_as] > “64511” { mutate { replace => { “[netflow][dst_as]” => “2635” } } }

# Multiply by sampling interval to calculate the total bytes and packets the flow represents if [netflow][sampling_interval] > 0 { ruby { code => “event[‘netflow’][‘in_bytes’] = event[‘netflow’][‘in_bytes’] * event[‘netflow’][‘sampling_interval’]” add_tag => [ “multiplied” ] } ruby { code => “event[‘netflow’][‘in_pkts’] = event[‘netflow’][‘in_pkts’] * event[‘netflow’][‘sampling_interval’]” } } # add a bits field if [netflow][in_bytes] { ruby { code => “event[‘netflow’][‘in_bits’] = event[‘netflow’][‘in_bytes’] * 8” } }

#Protocol friendly naming translate { field => “[netflow][protocol]” destination => “[netflow][protocol]” override => “true” dictionary => [ “6”, “TCP”, “17”, “UDP”, “1”, “ICMP”, “47”, “GRE”, “50”, “ESP” ] }

# get the datacenter from hostname translate { field => “host” destination => “datacenter” dictionary => [ “hostname”, “citycode”, …] }

Translate to add friendly names instead of all numbers, such as, tcp flags, tcp/udp ports, interface names and hostnames.

if [host] == “hostname” { translate { field => “[netflow][input_snmp]” destination => “[netflow][interface_in]” dictionary => [ “633”, “xe-1/0/0” ] add_field => { direction => “inbound” traffic_type => “transit” provider => “ntt” } } translate { field => “[netflow][output_snmp]” destination => “[netflow][interface_out]” dictionary => [ “633”, “xe-1/0/0”] add_field => { direction => “outbound” traffic_type => “transit” provider => “ntt” } }

The filters can be used to add the GeoIP data, ASN including network name which is useful for routers that don’t have full BGP table.

if “inbound” == [direction] { geoip { database => “/home/logstash/config/GeoLiteCity.dat” source => “[netflow][ipv4_src_addr]” target => “geoip_src” }

CIDR to tell Logstash about prefixes that have special meanings.

# Tag Interesting traffic by prefix cidr { add_field => { “interesting” => true } address => [ “%{[netflow][ipv4_src_addr]}”, “%{[netflow][ipv4_dst_addr]}” ] network => [ “100.0.0.0/24” ] }

Sflow

Logstash does not have a native sflow collector, so we used Sflow tool to convert sflow to netflow. Another option is to parse the text output of Sflow tool as a pipe input to Logstash and set up the fields using the grok filter.

The future

IPv6/IPFIX/NetflowV9

Kibana supports NetflowV9 which can include IPv6 addresses and send flow data more efficiently. There is a patch for IPFIX with support being added soon. There are still some things being worked out, for example the GeoIP database filter doesn’t work with IPv6. This creates some filtering limitations, especially if you don’t have a full routing table router and want to group traffic by ASN or location.

Alerting

This is a new system for us and we are still tweaking and getting used to the data, so alerting is not yet configured. Alerting is definitely an important part of network monitoring. Using flow data to trigger alerts can go well beyond the limitations of SNMP queries and traps. Some have made their own scripts to query Elastic(search), match the response with a threshold value, and then alert if it’s exceed. There are even plugins for Nagios that can query Elastic, parse the response and trigger an alert if required. Elastic.co also has a paid tool called Watcher that can serve this purpose.

Feature Request – Netflow.

Hello Fluentd Devs and other coders,I don’t know if this is the proper place to request a feature or even if I over stepping my bounds but I would like to request a feature for fluentd. If I am wrong then please let me know, but I would like to see netflow in fluentd. As either a plugin or a feature.The reason I am asking this is because Logstash supports a codec called netflow. This allows monitoring of network traffic and allowing people to view network traffic as logs.Another Engineer and I have played around with Fluentd trying to get this to work but logstash already has something for it. Below is the basic config of Logstash that I am using in DevOps with Fluentd. Both work great together and I have no problem using them both. However, I would like to keep my servers less complex, and not run Fluentd and Logstash together.input {udp {type => “netflow”host => “127.0.0.1”port => 9995codec => “netflow”output {elasticsearch {host => “127.0.0.1”index => “logstash-%{+YYYY.MM.dd.HH}”This works with softflowd to produce traffic on the network in the form of logs. I am not a Ruby coder so I wouldn’t even know where to start with trying to convert this to a plugin for fluentd. Also, If anyone has actually done netflow with fluentd before let me know because I am interested.Thanks,

Logstash netflow plugin configuration error

I’m trying to use logstash to collect traffic information from VMware ESXi using the netflow plugin.

I’ve installed the latest version of logstash and elasticsearch from www.elastic.co on Ubuntu 16.04.1 with openjdk 8 installed.

I’ve created this config file:

input { udp { host => localhost port => 9995 codec => netflow { versions => [10] target => ipfix } type => ipfix } } output { stdout { codec => rubydebug } elasticsearch { index => “logstash_netflow5-%{+YYYY.MM.dd}” host => “localhost” } }

but when I execute:

logstash -f logstash-staticfile-netflow.conf

I got the following:

Pipeline aborted due to error {:exception=>”LogStash::ConfigurationError”, :backtrace=>[“/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/config/mixin.rb:88:in config_init'”, “org/jruby/RubyHash.java:1342:ineach'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/config/mixin.rb:72:in config_init'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/outputs/base.rb:79:ininitialize'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/output_delegator.rb:74:in register'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/pipeline.rb:181:instart_workers'”, “org/jruby/RubyArray.java:1613:in each'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/pipeline.rb:181:instart_workers'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/pipeline.rb:136:in run'”, “/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.4.0-java/lib/logstash/agent.rb:491:instart_pipeline'”], :level=>:error} No matching template for flow id 256 {:level=>:warn} stopping pipeline {:id=>”main”}

Do you have any idea why I have this error? Thanks in advance for any help!
