Because it took me forever to piece this simple code together
import netsnmp
session = netsnmp.Session( DestHost='your.host.com', Version=2, Community='public' )
vars = netsnmp.VarList( netsnmp.Varbind('.1.3.6.1.4.1.2021.8.1.101.1') )
print( session.get(vars) )
counter=`cat /tmp/counter` ; echo "$counter+1" | bc > /tmp/counter
note that loading the /tmp/counter into the variable is a necessary indirection, the following:
echo "`cat /tmp/counter`+1" | bc > /tmp/counter
would not work as the output redirection gets triggered before the cat gets a chance to happen, so the file is emptied too early.
Here are a bunch of datasets accumulated over the years for different projects, have fun with them! If you have something to augment this list with, let me know.
