SNMP Modular Input

1.8.6

• upgraded the internal Splunk Python SDK to v2.0.2.
• this release will require Python version 3 to run

1.8.5

• added a custom config file, snmpv3usmusers.conf , which will allow you to setup multiple SNMPv3 USM Users for receiving Traps on the same port.

1.8.4

• in some rare circumstances , and only on Windows , there may be permission errors rolling log files when you have configured multiple stanzas.Added a patch to uniquely name log files on a per stanza basis.

1.8.3

• added some code that calls tasklist on Windows to detect and kill rogue snmp.py processes
• a few minor code tidyups

1.8.2

• some minor regex field extraction tweaks to the snmpattributes and snmptraps sourcetypes

1.8.1

• fixed some incorrect extractions for sourcetypes
• added more authentication protocols for SNMPv3

1.8.0

• general robustification around MIB loading/compiling and better error messages to help diagnose issues with your custom vendor MIBs

1.7.9

• upgraded the Splunk Python SDK to v 1.6.18 to meet the latest App Inspect/Cloud Vetting rules.

1.7.8

• added low level pysnmp library debug logging to the logging output if level "DEBUG" is chosen

1.7.7

• can now configure an engine id for a USM User for receiving v3 traps

1.7.6

• Patch pysnmp for COUNTER/TIMETICKS encodings that might decode into a negative value

1.7.5

• ensure DefaultResponseHandler doesn't emit empty content
• ensure that retrieved credentials always contain some placeholder String value in case no password values are returned from Splunk's REST API

1.7.4

• added flag to optionally disable process state checking

1.7.3

• fix to Process state checking for Windows environment

1.7.2

• do not index end of MIB view messages for SNMP walking operations in the Default Response Handler.

1.7.1

• minor patch to tighten up lifecycle checking of the SNMP process

1.7

• updated the core version of pysnmp to the latest v4.4.12
• updated the core version of pyasn1 to the latest v0.4.8
• general code refactoring to support the new libraries and maintain backwards compatibility
• added the pysmi library v0.3.4 to support compiling MIBs to Python modules at runtime
• for SNMP v3 , the pycrypto package is no longer required , instead you should now use the pycryptodomex package. More details in the README docs on installing the pycryptodomex package.
• plain text MIBS can now be added to the configuration and will be automatically compiled into Python modules for you , no more need to pre compile (although you can still pre compile if you wish using the built in midbump.py script)
• can now toggle lexicographic mode on/off for SNMP walking operations using GETNEXT and GETBULK. This setting governs if the entire MIB should be walked to the end or just the OIDs within the scope of the OIDs you start walking from.
• better informational logging
• added 2 new default sourcetypes with better timestamp extraction , snmp_traps and snmp_attributes
• added the option to use a System python rather than Splunk's built-in python , which you'll need for installing/running SNMP v3 dependencys
• adding in self monitoring logic to kill any snmp.py processes that splunkd doesn't kill when you disable an input.
• removed the dependency on the splunk package from site-packages. Now using the Splunk Python SDK for all API operations.
