Panoptes SNMP

A Python wrapper on Net-SNMP

Table of Contents

Introduction

This library, which is a fork of the excellent EasySNMP library, provides a Pythonic wrapper on top of Net-SNMP C library.

Background

The key differences from the upstream library are:

  • Includes Net-SNMP source code which is used to build shared objects during installation leading to self contained distributions
  • Locks down options for the Net-SNMP library: for example, SNMPv1 is and applications are disabled
  • No MIBs are include in the distribution - this is by design since using symbolic OIDs is slow
  • A Python based implementation of bulk_walk
  • Fix support for tunneled SNMP connections

Install

Install by running the following commands:

pip install yahoo_panoptes_snmp

Usage

The API is similar to that of EasySNMP, which is documented here

bulk_walk

The implementation of BULKWALK is based on doing BULKGETs and using 'falling out' of the OID tree to terminate.

The method signature is as follows:

def bulk_walk(self, oids, non_repeaters=0, max_repetitions=10):
    """
    Performs a series of bulk SNMP GET operation using the prepared session to
    retrieve multiple pieces of information in a single packet.

    :param oids: you may pass in a list of OIDs or single item; each item
                 may be a string representing the entire OID
                 (e.g. 'sysDescr.0') or may be a tuple containing the
                 name as its first item and index as its second
                 (e.g. ('sysDescr', 0))
    :param non_repeaters: the number of objects that are only expected to
                          return a single GETNEXT instance, not multiple
                          instances
    :param max_repetitions: the number of objects that should be returned
                            for all the repeating OIDs
    :return: a list of SNMPVariable objects containing the values that
             were retrieved via SNMP
    """
