Python NET-SNMP Binding

netsnmp-py3

Python NET-SNMP Bindings (C Extension)

https://pypi.python.org/pypi/netsnmp-py

Supports Python 2.7 and 3.x

Currently only supports SNMPv1 and SNMPv2c polling (GET, GETNEXT, WALK)

Support for SET and TRAP, as well as SNMPv3 is planned

Overview

Pip Install

Debian testing/unstable (py2.7)

# apt-get install libsnmp30 libsnmp30-dev python-zmq libczmq3 libczmq-dev
# pip install netsnmp-py

Debian testing/unstable (py3)

# apt-get install libsnmp30 libsnmp30-dev libczmq3 libczmq-dev
# pip3 install pyzmq
# pip3 install netsnmp-py

Manual Setup

Recommended to build this against a manually compiled NET-SNMP source - no need to install:

$ pwd
/Build/net-snmp-5.7.3

$ ./configure --prefix=/opt --enable-ucd-snmp-compatibility --enable-ipv6 --with-defaults
..
$ make
..

Build the netsnmp C extension and check LDD for proper library linking, configure ld.so.conf if nescessary:

$ python3 setup.py --basedir=/Build/net-snmp-5.7.3 build_ext -i

Basic usage:

SNMP GET:

>>> with netsnmp.SNMPSession('archt01', 'public') as ss:
...     ss.get(['.1.3.6.1.2.1.1.1.0', '.1.3.6.1.2.1.1.3.0', '.1.3.6.1.2.1.1.5.0'])
... 
[('.1.3.6.1.2.1.1.1.0', 'STRING', '"Linux archt01 4.3.0-1-ck #1 SMP PREEMPT Sun Nov 15 13:24:29 EST 2015 x86_64"'), ('.1.3.6.1.2.1.1.3.0', 'Timeticks', '1:11:36:30.56'), ('.1.3.6.1.2.1.1.5.0', 'STRING', '"archt01"')]

SNMP GETNEXT:

>>> with netsnmp.SNMPSession('archt01', 'public') as ss:
...     ss.getnext(['.1.3.6.1.2.1.1.1', '.1.3.6.1.2.1.1.2.0', '.1.3.6.1.2.1.1.4.0'])
... 
[('.1.3.6.1.2.1.1.1.0', 'STRING', '"Linux archt01 4.3.0-1-ck #1 SMP PREEMPT Sun Nov 15 13:24:29 EST 2015 x86_64"'), ('.1.3.6.1.2.1.1.3.0', 'Timeticks', '1:11:39:35.05'), ('.1.3.6.1.2.1.1.5.0', 'STRING', '"archt01"')]

SNMP WALK (generator):

>>> with netsnmp.SNMPSession('archt01', 'public') as ss:
...     [response for response in ss.walk(['.1.3.6.1.4.1.2021.10.1.3'])]
... 
[('.1.3.6.1.4.1.2021.10.1.3.1', 'STRING', '"0.37"'), ('.1.3.6.1.4.1.2021.10.1.3.2', 'STRING', '"0.25"'), ('.1.3.6.1.4.1.2021.10.1.3.3', 'STRING', '"0.29"')]

IPv6 support:

>>> with netsnmp.SNMPSession('udp6:[fe80::c67:bb2b:dbb4:8c63]', 'public') as ss:
...     ss.get(['.1.3.6.1.2.1.1.1.0'])
...
