fastsnmp

SNMP poller oriented to poll bunch of hosts in short time. Package include poller and SNMP coder/encoder library.

[Reference manual] (http://fastsnmp.readthedocs.org/)

Example:

from fastsnmp import snmp_poller

hosts = ("127.0.0.1",)
# oids in group must be with same indexes
oid_group = {"1.3.6.1.2.1.2.2.1.2": "ifDescr",
             "1.3.6.1.2.1.2.2.1.10": "ifInOctets",
             }

community = "public"
snmp_data = snmp_poller.poller(hosts, [list(oid_group)], community)
for d in snmp_data:
    print ("host=%s oid=%s.%s value=%s" % (d[0], oid_group[d[1]], d[2], d[3]))

Output:

host=127.0.0.1 oid=ifInOctets.1 value=243203744
host=127.0.0.1 oid=ifDescr.1 value=b'lo'
host=127.0.0.1 oid=ifInOctets.2 value=1397428486
host=127.0.0.1 oid=ifDescr.2 value=b'eth0'

Type conversion:

SNMP	Python
octetstring, ipaddress	bytes
null	None
objectid	str
counter32, unsigned32, gauge32, counter64, integer	int
noSuchInstance	None
noSuchObject	None
endOfMibView	None

Notices:

• ipaddress can be converted to string using str(ipaddress.IPv4Address(b"\x01\x01\x01\x01")) or socket.inet_ntoa(b"\x01\x01\x01\x01")

Another python SNMP libraries:

• PySNMP - very good SNMP library
• libsnmp - SNMP coder/decoder (abandoned project)
• Bindings to Net-SNMP
