The up.time Net-SNMP agent type is intended for server platforms. Most network devices (e.g. switches, routers, firewalls, etc.) do not have the full set of required MIB information and should be added as Network Device elements.
up.time depends on the following MIBs for the Net-SNMP type:
- RFC-1213 (.1.3.6.1.2.1)
- UCD-SNMP-MIB (.1.3.6.1.4.1.2021)
- HOST-RESOURCES-MIB (.1.3.6.1.2.1.25)
To test if your device is hosting these MIBs, use the snmpwalk command from any Linux server or an SNMP browsing utility on your desktop to attempt browsing the OIDs listed above. Here are some examples using snmpwalk from the command line:
# snmpwalk -v 2c -c <community string> <hostname> .1.3.6.1.2.1 # snmpwalk -v 2c -c <community string> <hostname> .1.3.6.1.2.2021 # snmpwalk -v 2c -c <community string> <hostname> .1.3.6.1.2.25
