OpenVMS computer system sensor

The OpenVMS computer system sensor discovers computer systems running the OpenVMS operating system.

Sensor name that is used in the GUI and logs



To run a successful discovery with the OpenVMS computer system sensor, you must complete the following prerequisite tasks:
  • Grant the discovery user the following privileges:
    • CMKRNL
    • NETMBX
    • SYSLCK
    • TMPMBX
    • WORLD
  • Set the PGFLQUOTA parameter to 327680.


All computer system sensors and the SNMP MIB2 sensor ignore network interfaces that are configured to be down. TADDM does not populate the net.IpNetwork attribute on the following types of IP interfaces:
  • loopback, for example,, 0:0:0:0:0:0:0:1
  • link-local, for example,, FE80:0:0:0:0:0:0:1
  • multicast, for example,, FF00:0:0:0:0:0:0:1
  • unspecified, for example,, 0:0:0:0:0:0:0:0
Therefore, IP networks are not populated in the TADDM user interface.

Model objects created

The sensor creates the following model objects:

  • core.LogicalContent
  • sys.openvms.OpenVms
  • sys.openvms.OpenVmsUnitaryComputerSystem
