That's the DA server discovered as an SNMP managed device correct? The one showing multiple types?
Is there a single SNMP agent on the server?
Did the system, or did configuration, allow it to be tied to discover as Router/Firewall and Server via Monitoring Profile to Collection associations?
The missing CPU, Disk, Memory and Partition metrics might be due to the Metric Families for those Vendor Certifications not being tied to the device via a Monitoring Profile to Collection association. Not all Metric Families are tied back to Collections by default.
