About health and utilization monitoring system (HUMS)
The R&S SMW comes with a health and utilization monitoring system (HUMS) provid-
ing information about the R&S SMW. Aim is to increase the overall utilization, to avoid
downtime and to increase the overall security level of a fleet of instruments.
HUMS provides, for example, information about:
●
Instrument identification, hardware components, software packages, licenses
●
Usage of remote control, usage via keyboard / mouse, usage of test applications
●
Hardware utilization and status, including S.M.A.R.T. data of the system drive
●
User-defined static information, for example, an inventory code
Interfaces and protocols
The HUMS installation on the R&S SMW includes an SNMP agent and a REST service
with HTTP endpoints. So you can access the health and usage information via LAN,
using the SNMP protocol or the REST protocol. Accessing the data does not interfere
with remote control via SCPI commands or with measurement execution.
Reference information for both protocols is available on the R&S SMW at the address
http://<instrument>/api/hums/v1/documents?name=<interface>.
For <instrument>, enter the hostname (e.g. SMW200A-102030) or the IP address (e.g.
10.121.0.34) of your instrument, as for access to the GUI.
For <interface> = snmp, you get a .zip file containing the MIB files for SNMP. For
<interface> = rest, you get a web page with the OpenAPI specification of the REST
API.
Address example: http://SMW200A-102030/api/hums/v1/documents?name=snmp.
