SNMP is not providing the full details on the health of the system. There are only the lo, eth0, and bond0 interfaces showing.
Release : 8.2.x
There are two lines which must be updated in /etc/snmp/snmpd.conf.tmpl file for snmp to work.
You will need to add one line and update another to enable the full SNMP oid list.
You will need to update the snmpd.conf file with one additional line and uncomment another.
The snmpd.conf.tmpl file you want to edit is in /etc/snmp on Security Analytics. This will require root access from an SSH prompt.
Before the change, there were 27 entries. After the change, we see 500+ including cpu load, memory usage, disk usage, and temperatures. There will be no information on the capture interfaces because they are not under control of the Linux kernel. They are controlled by the dpdk system.
You can test with "snmpwalk -v 1 -m SNMPv2-MIB -c public ip_address .1.3.6.1.4" or from the same SA server with snmpwalk -v 1 -m SNMPv2-MIB -c public localhost .1.3.6.1.4
