LibraryIntroductionEasy SNMP is a fork ofNet-SNMP Python
Bindingsthat attempts to bring a more Pythonic interface to the library. Check
out theNet-SNMP websitefor more
information about SNMP.This module provides a full-featured SNMP client API and supports all
dialects of the SNMP protocol.Why Another Library?Theoriginal Net-SNMP Python
libraryis a great starting point but is quite un-Pythonic and lacks proper unit tests and documentation.PySNMPis entirely written in Python
and therefore has a huge performance hit. In some brief tests, I
estimate that both the Net-SNMP Python bindings and Easy SNMP are more than 4 times faster than PySNMP. Further to this, PySNMP has an even less Pythonic interface than the official Net-SNMP bindings.Many other libraries likeSnimpyare sadly based on PySNMP, so they also suffer performance penalty.Quick StartThere are primarily two ways you can use the Easy SNMP library:1. By using a Session object which is most suitable
when you want to request multiple pieces of SNMP data from a
source:fromeasysnmpimportSession# Create an SNMP session to be used for all our requestssession=Session(hostname='localhost',community='public',version=2)# You may retrieve an individual OID using an SNMP GETlocation=session.get('sysLocation.0')# You may also specify the OID as a tuple (name, index)# Note: the index is specified as a string as it can be of other types than# just a regular integercontact=session.get(('sysContact','0'))# And of course, you may use the numeric OID toodescription=session.get('.1.3.6.1.2.1.1.1.0')# Set a variable using an SNMP SETsession.set('sysLocation.0','The SNMP Lab')# Perform an SNMP walksystem_items=session.walk('system')# Each returned item can be used normally as its related type (str or int)# but also has several extended attributes with SNMP-specific informationforiteminsystem_items:print'{oid}.{oid_index}{snmp_type}={value}'.format(oid=item.oid,oid_index=item.oid_index,snmp_type=item.snmp_type,value=item.value)2. By using Easy SNMP via its simple interface which is intended
for one-off operations (where you wish to specify all details in the
request):fromeasysnmpimportsnmp_get,snmp_set,snmp_walk# Grab a single piece of information using an SNMP GETsnmp_get('sysDescr.0',hostname='localhost',community='public',version=1)# Perform an SNMP SET to update datasnmp_set('sysLocation.0','My Cool Place',hostname='localhost',community='public',version=1)# Perform an SNMP walksnmp_walk('system',hostname='localhost',community='public',version=1)DocumentationPlease check out theEasy SNMP documentation at Read the
Docs. This includes installation
instructions for various operating systems.You may generate the documentation as follows:# Install Sphinxpipinstallsphinx# You may optionally export the READTHEDOCS environment variable to build docs
