    This is documentation for Mothra, a collection of Scala and Spark library functions for working with Internet-related data.

    This is documentation for Mothra, a collection of Scala and Spark library functions for working with Internet-related data. Some modules contain APIs of general use to Scala programmers. Some modules make those tools more useful on Spark data-processing systems.

    Please see the documentation for the individual packages for more details on their use.

    Scala Packages

    These packages are useful in Scala code without involving Spark:

    org.cert.netsa.data

    This package, which is collected as the netsa-data library, provides types for working with various kinds of information:

    org.cert.netsa.io.ipfix

    The netsa-io-ipfix library provides tools for reading and writing IETF IPFIX data from various connections and files.

    org.cert.netsa.io.silk

    To read and write CERT NetSA SiLK file formats and configuration files, use the netsa-io-silk library.

    org.cert.netsa.util

    The "junk drawer" of netsa-util so far provides only two features: First, a method for equipping Scala scala.collection.Iterators with exception handling. And second, a way to query the versions of NetSA libraries present in a JVM at runtime.

    Spark Packages

    These packages require the use of Apache Spark:

    org.cert.netsa.mothra.datasources

    Spark datasources for CERT file types. This package contains utility features which add methods to Apache Spark DataFrameReader objects, allowing IPFIX and SiLK flows to be opened using simple spark.read... calls.

    The mothra-datasources library contains both IPFIX and SiLK functionality, while mothra-datasources-ipfix and mothra-datasources-silk contain only what's needed for the named datasource.

    org.cert.netsa.mothra.analysis

    A grab-bag of analysis helper functions and example analyses.

    org.cert.netsa.mothra.functions

    This single Scala object provides Spark SQL functions for working with network data. It is the entirety of the mothra-functions library.

    The org.cert.netsa.data.net package is for working with network-related data.

    The org.cert.netsa.data.net package is for working with network-related data. This includes types for IP addresses, port numbers, protocol numbers, and the like. Many of these types have namespaces managed by IANA, and the types provide mechanisms for looking up names from numbers and vice-versa based on embedded copies of IANA's tables.

    In org.cert.netsa.data.time you can find an Ordering for Java LocalDate objects, and a type LocalDateSet for working with sets of those dates.

    Finally, org.cert.netsa.data.unsigned contains types for working with unsigned integer values.

Type Members

  1. class ExceptionGuardedIterator[T] extends Iterator[T]

    An Iterator that wraps another Iterator with protection for exceptions during iteration.

    An Iterator that wraps another Iterator with protection for exceptions during iteration. If an exception occurs while calling hasNext or next, the provided exception handler will be called, and the ExceptionGuardedIterator will act as if it is now empty.

    Construction using the companion object will also handle exceptions produced when getting the initial wrapped Iterator.

Value Members

  1. object ExceptionGuardedIterator
  2. object versionInfo extends LazyLogging

    Information about versions of CERT NetSA jar files on the classpath, for identification and debugging purposes.

    Information about versions of CERT NetSA jar files on the classpath, for identification and debugging purposes. This is based on the presence of resources under /org/cert/netsa/versionInfo/<name>.properties which are created automatically at build time.
