Superfast snmp bulkwalk method implemented using net-snmp bindings for getbulk
Fastsnmpy is a module that leverages python-extensions that come with net-snmp and provide highly parallelized faster-methods to walk oid-trees on devices.
In addition, it provides a method to bulkwalk mib-trees. BulkWalk methods are missing from native python-bindings for net-snmp. By creating a wrapper around the GetBulk method instead, and maintaining state while traversing the oid-tree, fastsnmpy provides a clever solution to bulkwalk oids much faster.
It provides the following methods as of Fastsnmpy-1.2.1
snmpwalk(): Native python-bindings distributed with net-snmp, combined with fastsnmpy’s ability to parallelize snmpwalk operations.
snmpbulkwalk(): Ability to snmpbulkwalk devices, which makes it several magnitudes faster than net-snmp’s implementation of snmpwalk.
By leveraging the getbulk method, this module provides a quick snmpbulkwalk utility.
PROCESS-POOLS: By passing in a ‘workers=n’ attribute to the above methods, fastsnmpy can instantiate a process-pool to parallelize the snmpwalk and snmpbulkwalk methods, resulting in several devices being walked at the same time, effectively using all cores on a multicore machine.
One-Line, and Two-Line scripts that enable you to discover/walk all devices in a whole datacenter
Both Linux and Windows support
