SNMP Commands

The following explains some commands to get and walk SNMP mib trees.

Note in the cases below we are using SNMP Version 1 commands to communicate based on community string.

See also "How to Setup SNMP on Sco"

1. Walk the SNMP Tree
# snmpwalk -v1 -c public server
(i.e. use version 1 snmp with the public community string to display the entire tree on the server "server")

2. Specifically find filesystem labels and sizes

(Note your OID, 1.3.6.1.2.1.25.2.3.1.3 may be different, best to do an snmpwalk and find the OID your after)
# snmpwalk -v1 -c public server 1.3.6.1.2.1.25.2.3.1.3 HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Filesystem /dev/boot HOST-RESOURCES-MIB::hrStorageDescr.2 = STRING: Filesystem /dev/root HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Filesystem /dev/u HOST-RESOURCES-MIB::hrStorageDescr.4 = STRING: Filesystem /dev/u2 HOST-RESOURCES-MIB::hrStorageDescr.5 = STRING: Filesystem /dev/v HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: swap HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: queues HOST-RESOURCES-MIB::hrStorageDescr.8 = STRING: streams msg blocks HOST-RESOURCES-MIB::hrStorageDescr.9 = STRING: streams data blocks<br /># snmpwalk -v1 -c public server 1.3.6.1.2.1.25.2.3.1.5 HOST-RESOURCES-MIB::hrStorageSize.1 = INTEGER: 19968 HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 2999910 HOST-RESOURCES-MIB::hrStorageSize.3 = INTEGER: 9210982 HOST-RESOURCES-MIB::hrStorageSize.4 = INTEGER: 19999948 HOST-RESOURCES-MIB::hrStorageSize.5 = INTEGER: 20284824 HOST-RESOURCES-MIB::hrStorageSize.6 = INTEGER: 1538000 HOST-RESOURCES-MIB::hrStorageSize.7 = INTEGER: 1704 HOST-RESOURCES-MIB::hrStorageSize.8 = INTEGER: 3855 HOST-RESOURCES-MIB::hrStorageSize.9 = INTEGER: 3914872
use snmpget to actually retrieve data, like what mrtg would do
# snmpget -v1 -c public server 1.3.6.1.2.1.25.2.3.1.6.2 HOST-RESOURCES-MIB::hrStorageUsed.2 = INTEGER: 1878528
