<p>This codec is used to parse <a href="https://nmap.org/" class="ulink" target="_top">nmap</a> output data which is serialized in XML format. Nmap ("Network Mapper") is a free and open source utility for network discovery and security auditing.
For more information on nmap, see <a href="https://nmap.org/" class="ulink" target="_top">https://nmap.org/</a>.</p>
<p>Note: This codec can only be used for decoding data.</p>
<p>Event types are listed below</p>
<p><code class="literal">nmap_scan_metadata</code>: An object containing top level information about the scan, including how many hosts were up, and how many were down. Useful for the case where you need to check if a DNS based hostname does not resolve, where both those numbers will be zero.
<code class="literal">nmap_host</code>: One event is created per host. The full data covering an individual host, including open ports and traceroute information as a nested structure.
<code class="literal">nmap_port</code>: One event is created per host/port. This duplicates data already in <code class="literal">nmap_host</code>: This was put in for the case where you want to model ports as separate documents in Elasticsearch (which Kibana prefers).
<code class="literal">nmap_traceroute_link</code>: One of these is output per traceroute <em>connection</em>, with a <code class="literal">from</code> and a <code class="literal">to</code> object describing each hop. Note that traceroute hop data is not always correct due to the fact that each tracing ICMP packet may take a different route. Also very useful for Kibana visualizations.</p>
