HP-UX computer system sensor

The HP-UX computer system sensor discovers a computer system that is running the HP-UX operating system. If a system is running HP-UX on an Itanium platform with virtualization support (HP Integrity Virtual Machines), the sensor discovers elements that are managed by the server.

Sensor name that is used in the GUI and logs

HpUxComputerSystemSensor

Prerequisites

For a VM Host system on an Itanium platform, the Agile Service Manager service account must have Execute permissions on the hpvmstatus and hpvminfo binary files.

For a guest system on an Itanium platform, the Agile Service Manager service account must have Execute permissions on the hpvminfo binary files.

The Agile Service Manager service account must have Execute permissions on the machinfo binary files.

Limitations

All computer system sensors and the SNMP MIB2 sensor ignore network interfaces that are configured to be down. Agile Service Manager does not populate the net.IpNetwork attribute on the following types of IP interfaces:
  • loopback, for example, 127.0.0.1, 0:0:0:0:0:0:0:1
  • link-local, for example, 169.254.1.1, FE80:0:0:0:0:0:0:1
  • multicast, for example, 224.0.0.1, FF00:0:0:0:0:0:0:1
  • unspecified, for example, 0.0.0.0, 0:0:0:0:0:0:0:0
Therefore, IP networks are not populated in the Agile Service Manager user interface.
The following limitations when discovering CPU information through the HP-UX Computer System sensor apply:
  • The sensor doesn't discover 'CPUCoresInstalled' for PA-RISC architecture.
  • The sensor doesn't discover threads number for CPU - HyperThreading configuration.
  • The sensor doesn't discover 'CPUDiesInstalled' if command 'mpsched -K' is unavailable.
  • The sensor doesn't discover 'CPUCoresInstalled' if command 'icapstatus' is unavailable.
  • The sensor doesn't discover cpu/cores configuration if command 'mpsched -K' is unavailable.

Discovery of IPv6 address of a guest system through a VM Host is not available for HP-UX on an Itanium platform. Discovery of IPv6 address of a VM Host through a guest system is not available for HP-UX on an Itanium platform.

Guest systems that are running non-HP-UX operating systems are not created during discovery of the VM host systems.

Agile Service Manager is unable to discover CPU cores information of IVM guest, which is directly discovered by the sensor. This happens because the icapstatus command is not supported on the IVM guest.

Discovery of IPv6 interfaces and IPv6 routing and forwarding information

The sensor discovers IPv6 interfaces and IPv6 routing and forwarding information about target systems that are configured to support IPv6. Agile Service Manager runs discoveries against only IPv4 addresses. Agile Service Manager does not start a sensor against IPv6 addresses. For DNS lookups, Agile Service Manager uses either the IPv4 or the IPv6 addresses. Agile Service Manager does not populate the net.IpNetwork attribute on an IPv6 interface if the prefix length value is unspecified or equals zero.

The discovered IPv6 addresses are displayed in the Agile Service Manager user interface similarly to IPv4 addresses and are accessible using the Agile Service Manager API. Because IPv6 addresses use a prefix length value instead of an IPv4 netmask, only one of these values is populated for an IP address. The value depends on the address type.

Model objects created

The sensor creates the following model objects:

  • core.LogicalContent
  • sys.hpux.HpUx
  • sys.HpUxUnitaryComputerSystem
  • sys.OperatingSystem
  • sys.SoftwareComponent
