Flow data can be used for a variety of troubleshooting tasks, including:<\/p>\r\n<ul>\r\n<li>Network performance<\/li>\r\n<li>Capacity planning<\/li>\r\n<li>Security audits<\/li>\r\n<li>\u2026 and more<\/li>\r\n<\/ul>\r\n<p>The key to understanding how to analyze flow data is first to understand what information is contained within flow exports, and then we can see what to do with that data. In this article, we will explore flow (NetFlow, IPFIX, SFlow\u2026) and then see how to analyze that data with StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup>.<\/p>\r\n<p>The best way to describe flow data is to call it meta data, i.e. information \u201cabout\u201d the data, without exposing the actual data. I think a good way to understand this is to think about mailing a package like a FedEx. If you could inspect the package, you could get a lot of information about the delivery. You could know who sent it, and to whom it was being sent. You could also get some valuable information about it like how big it is, how heavy and so forth. You couldn\u2019t see \u201cinside\u201d the package, so the contents wouldn\u2019t be exposed, but you could still \u201cknow\u201d quite a lot of \u201cmeta data\u201d about it.<\/p>\r\n<p>The same is true for flow. Contained within the flow exports are valuable pieces of information about the packets being sent across your network. Information like:<\/p>\r\n<ul>\r\n<li>Input interface index used by SNMP (ifIndex in IF-MIB)<\/li>\r\n<li>Output interface index or zero if the packet is dropped<\/li>\r\n<li>Timestamps for the flow start and finish time, in milliseconds since the last boot<\/li>\r\n<li>Number of bytes and packets observed in the flow<\/li>\r\n<li>Layer 3 headers:\r\n<ul>\r\n<li>Source &amp; destination IP addresses<\/li>\r\n<li>ICMP type and code<\/li>\r\n<li>IP protocol<\/li>\r\n<li>Type of Service (ToS) value<\/li>\r\n<\/ul>\r\n<\/li>\r\n<li>Source and destination port numbers for TCP, UDP, SCTP<\/li>\r\n<li>For TCP flows, the union of all TCP flags observed over the life of the flow<\/li>\r\n<li>Layer 3 routing information:\r\n<ul>\r\n<li>IP address of the immediate next-hop (not the BGP next-hop) along the route to the destination<\/li>\r\n<li>Source &amp; destination IP masks (prefix lengths in the CIDR notation)<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<p>Also, many new vendor-specific forms of flow exist which provide even greater level of detail and more granular information. Cisco, Juniper, Ixia, Alcatel-Lucent, Huawei, and others support some level of flow customization within their devices.<\/p>\r\n<p>The StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup> Agent can be licensed to be a flow collector. So, you would point your flow-enabled devices like routers, switches, firewalls, probes, etc. to send their flows to the IP address of a StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup> Agent. From there you can use the StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup> GUI as well as the new StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup> Flow Portal to investigate the collected flow data.<\/p>\r\n<p>Flow data can be analyzed within StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup> in 2 main ways:<\/p>\r\n<ol>\r\n<li>Through real-time ad-hoc analysis (Agent Flow Query or Flow Portal)<\/li>\r\n<li>By setting up a specific measurement for longer term analysis (StableNet\u00ae Analyzer)<\/li>\r\n<\/ol>\r\n<p>Let\u2019s look at each of these in more detail.<\/p>\r[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_4&#8243; _builder_version=&#8221;3.0.47&#8243;][et_pb_team_member name=&#8221;Matthias Schmid&#8221; image_url=&#8221;https:\/\/www.infosim.net\/stablenet\/wp-content\/uploads\/5\/2018\/11\/matthias-schmid-infosim.jpg&#8221; disabled_on=&#8221;on|on|&#8221; admin_label=&#8221;Person (desktop)&#8221; _builder_version=&#8221;3.18.9&#8243; header_font=&#8221;|600|||||||&#8221;]<p>\r\nSolution Manager at Infosim<sup style=\"font-size: 50%;\">\u00ae<\/sup><\/p>\r[\/et_pb_team_member][et_pb_divider divider_weight=&#8221;2&#8243; disabled_on=&#8221;on|on|&#8221; admin_label=&#8221;Teiler (desktop)&#8221; _builder_version=&#8221;3.18.9&#8243; height=&#8221;0px&#8221; custom_margin=&#8221;||0px|&#8221; custom_padding=&#8221;0px||0px|&#8221;][\/et_pb_divider][et_pb_text disabled_on=&#8221;on|on|&#8221; admin_label=&#8221;Author (desktop)&#8221; _builder_version=&#8221;3.18.9&#8243; text_font=&#8221;|600|||||||&#8221; text_font_size=&#8221;18px&#8221; custom_margin=&#8221;0px|||&#8221; custom_padding=&#8221;0px|||&#8221;]<p>Author<\/p>\r[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; _builder_version=&#8221;3.22&#8243;][et_pb_row custom_padding=&#8221;0px||0px|&#8221; _builder_version=&#8221;3.22&#8243;][et_pb_column type=&#8221;3_4&#8243; _builder_version=&#8221;3.0.47&#8243;][et_pb_text admin_label=&#8221;I.

For example, if the user wanted a report that just shows email traffic between two IP subnets, they could create rules which match on the email ports (25, 587, 110\u2026) and also set up a filter for the subnets they want to look at. Then they can create an analyzer view to just display that result.<\/p>\r\n<p>By having a measurement, you can also now create monitors on the flow data to alert on things like the total number of flows, router traffic, packet size, matched flows, and so on. That way, a user can get an alarm if StableNet\u00ae detects too much (or not enough) traffic which can be a great indicator of network issues.<\/p>\r[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.infosim.net\/stablenet\/wp-content\/uploads\/5\/2018\/11\/Screenshot6_Analyzer-Window2.jpg&#8221; alt=&#8221;screenshot StableNet\u00ae chart flow data logarithmic&#8221; title_text=&#8221;StableNet\u00ae Analyzer&#8221; _builder_version=&#8221;3.22.2&#8243;][\/et_pb_image][et_pb_text _builder_version=&#8221;3.17.6&#8243;]<p>\r\nBy utilizing the many flow analysis features of StableNet<sup style=\"font-size: 50%;\">\u00ae<\/sup>, network engineers can dig much deeper into the details of their traffic for both real-time troubleshooting as well as long-term health and capacity\/trending data.
