CatPaw Rumors: Release Notes for 5.0 Release

We did analysis on #SNMP 4.0 before. This post is the latest one for 5.0.

A view of the work achieved

1

SELECT METHODS WHERE CodeWasChanged OR WasAdded

The codebase keeps evolves fast, and the picture shows a lot.

You can see a lot of highlighted areas, because

  1. We migrated to Visual Studio 2010, so many generated code has been changed.
  2. We changed a lot of GUI code in order to support Mono/openSUSE.
  3. Agent side SNMP v3 support introduces many underlying changes in the Library.
  4. Browser side SNMP v3 support introduces a few changes in itself.

New Core Public Types

SELECT TYPES FROM ASSEMBLIES "SharpSnmpLib","SharpSnmpLib.Controls", "SharpSnmpLib.Mib"
WHERE IsPublic AND WasAdded

Only three new types are introduced in 5.0,

  • MalformedMessage: It is used to represent an SNMP v3 message received by the listener, which cannot be decrypted successfully due to several reasons.
  • DecryptionException: An exception raised when an SNMP v3 message cannot be decrypted successfully.
  • ListenerBinding: We introduce this class, so you can ask a Listener class to monitor on several IP address:port number bindings.

New Assemblies

1

SELECT ASSEMBLIES WHERE WasAdded

Only one assembly is added to our binary release package. That is snmptranslate, a utility to show how to use compiled MIB documents to do OID translation.

New Public Types

SELECT TYPES WHERE WasAdded AND IsPublic

We have a few new types here except for the three mentioned above,

  • OutputPanelAppender: This is a custom log4net appender used in the Browser and the Compiler. It logs all necessary information into the output panel.
  • RollingFileAppender: This is a custom log4net rolling file appender that outputs log file names in IIS similar pattern.

Rambling

Our biggest changes are,

  1. The Agent and the Browser now support SNMP v3.
  2. The Agent, the Browser and the Compiler supports both .NET/Windows and Mono/openSUSE now.
  3. VB.NET samples are added.
