net snmp Tips

View configuration paths used in the build

snmpd -f -Lo -Dread_config -H 2>&1 | grep "config path" | head -1

For example (on MacOS):

read_config:path:
config path used for snmpd:
/etc/snmp:/usr/share/snmp:/usr/lib/snmp:/Users/oliver/.snmp
(persistent path:/var/db/net-snmp)`

Or even better, use net-snmp-config:

--configure-options   display original configure arguments
--prefix              display the installation prefix
--snmpd-module-list   display the modules compiled into the agent
--default-mibs        display default list of MIBs
--default-mibdirs     display default list of MIB directories
--snmpconfpath        display default SNMPCONFPATH
--persistent-directory display default persistent directory
--perlprog            display path to perl for the perl modules
