[root@TEST w-snmpwalk]# ./w-snmpwalk.py
usage: w-snmpwalk.py [-h] [--ver VER] [--comm COMM] [--port PORT]
[--datadir DATADIR] [--ip IP] [--ipfile IPFILE]
[--oid OID] [--oidfile OIDFILE] [--oldstyle] [--pysnmp]
[--silent] [--singlefile] [--max MAX] [--timeout TIMEOUT]
[--process]
This is a multi-device snmpwalk program, it works like snmpwalk command of
net-snmp project. So make sure you have installed snmpwalk before using it.
optional arguments:
-h, --help show this help message and exit
--ver VER SNMP version, default is 2c
--comm COMM SNMP community
--port PORT SNMP UDP port, default is 161
--datadir DATADIR The path where arp or mac data is stored, default is current directory
For example:
/var/log/snmp/$(date "+%Y")/$(date "+%Y%m%d")/
--ip IP ip[:port] list for snmp fetching
--ipfile IPFILE A filename of ip[:port] list, --ip has higher priority than --ipfile
--oid OID OID list for snmpwalk
--oidfile OIDFILE A filename of oid list, --oid has higher priority than --oidfile
--oldstyle For compatible, use an old format to log.
Old Style:
shell> cat /var/log/snmp/2015/20151123/172.17.54.1/172.17.54.1#ifHCInOctets.1
2015-11-23 12:58:57, ifHCInOctets.1 = Counter64: 2799462542644320;
New Style:
shell> cat /var/log/snmp/2015/20151123/172.17.54.1/ifHCInOctets.1
12:58:57, 2799462542644320
--pysnmp Use pysnmp module instead of snmpwalk command of net-snmp.
--silent Silence mode.
--singlefile If given then write all snmp output of one IP to single file.
--max MAX The maximum threads/processes could be spread each time, default is 1000.
--timeout TIMEOUT Time to wait for command executing, default is 5 seconds.
--process Use multi-process instead of multi-thread.
Example:
w-snmpwalk.py --comm <YOUR_COMM> --ip 192.168.0.1
w-snmpwalk.py --comm <YOUR_COMM> --datadir /var/log/snmp/2016/20160123/ --ipfile ./ip.test --silent
