namedtuple help - anna - Oct-18-2019
Hi All,
something is going wrong and not able to understand. below code is polling lag interface details. I am not able to print using namedtuple.
tLagOperationEntry_list = []
for host in my_devices:
try:
session = Session(hostname=host, community='cacti', version=2)
except easysnmp.EasySNMPConnectionError as e:
print('Error:- {}'.format(e))
sys.exit(1)
try:
tLagIfIndex,tLagConfigLastChange,tLagLACPPrimaryPort\
= (list(session.bulkwalk('1.3.6.1.4.1.6527.3.1.2.15.3.1.'+c, \
non_repeaters=0, max_repetitions=50))for c in ('1','2','5'))
except easysnmp.EasySNMPNoSuchInstanceError as e:
print('Error:- {}'.format(e))
finally:
tLagOperationEntry = namedtuple('tLagOperationEntry','LagIfIndex LagConfigLastChange LagLACPPrimaryPort')
LagOperationEntry_inters = [tLagOperationEntry(*uple) for uple in zip(*[tLagIfIndex,tLagConfigLastChange,tLagLACPPrimaryPort])]
for OperationEntry in LagOperationEntry_inters:
tLagOperationEntry = {}
tLagOperationEntry['host'] = host
tLagOperationEntry['interface_index'] = OperationEntry.LagIfIndex.value
tLagOperationEntry['LagConfigLastChange'] = OperationEntry.LagConfigLastChange.value
tLagOperationEntry['LagLACPPrimaryPort'] = OperationEntry.LagLACPPrimaryPort.value
tLagOperationEntry_list.append(tLags)
for data in tLagOperationEntry_list:
print(data['host'],data['interface_index'],data['LagConfigLastChange'],data['LagLACPPrimaryPort'])this code showing blank output, however I am able to print individual lists.Output:[<SNMPVariable value='1342177330' (oid='enterprises.6527.3.1.2.15.3.1.1.50', oid_index='', snmp_type='INTEGER')>, <SNMPVariable value='1342177331' (oid='enterprises.6527.3.1.2.15.3.1.1.51', oid_index='', snmp_type='INTEGER')>, <SNMPVariable value='1342177332' (oid='enterprises.6527.3.1.2.15.3.1.1.52', oid_index='', snmp_type='INTEGER')>]RE: namedtuple help - Larz60+ - Oct-18-2019
There is no other output from your script except lines 27 and 28, unless the except clauses get executed.

thanks Larz60+
one oid's output is not as per expectation, working on this.
RE: namedtuple help - buran - Oct-18-2019
and what is the purpose to create list of namedtuples and immediately to create a list of dicts?
RE: namedtuple help - anna - Oct-19-2019
Hi Buran,
is there another way? I am following below post, assigning value to variable before print.
