Entity and Attribute Definitions
Tandem Performance Data Collector (TPDC) Manual—526357-001
A-3
LDEVNUM Data Collection A NonStop Kernel-derived entity that provides
logical device number information.
LDISC
Measure-Derived Derived from the Measure DISC entity, contains
information about logical disk counters and
linkages.
LINE
Measure-Derived LINE counters and linkages. The LINE entity
contains information about one or more
communications lines.
MACHINE
Data Collection A NonStop Kernel-derived entity that provides
information associated with a CPU and its low-level
operation.
NETLINE
Data Collection NETLINE counters and linkages. The NETLINE
entity contains information about network
communications lines.
NODE
Data Collection A NonStop Kernel-derived entity that provides
information about the system or node.
NODENME
Data Collection An ASCII name entity that identifies nodes.
NODENUM
Data Collection A NonStop Kernel-derived entity that provides
node number information.
OPDISK
Data Collection OPDISK counters and linkages. The OPDISK
entity contains information about one or more
optical disk systems on the measured system.
OSSCPU
Measure-Derived OSSCPU counters and linkages. The OSSCPU
entity provides information about the Open System
Services elements that operate in each processor
of a system.
OSSNAMES
Data Collection OSS pathnames and Guardian file names with
MIDs.
OSSNS
Measure-Derived OSSNS counters and linkages. The OSSNS entity
provides information about the operation and
performance of OSS Name Server processes.
PART
Data Collection A disk directory entity that provides information
about partitioned files.
PDISC
Measure-Derived Derived from the Measure DISC entity; contains
information about physical disk counters and
linkages.
PGMTOTAL
SPAM Contains systemwide total process, logical file, and
DISCOPEN data.
PIDNUM
Data Collection An entity that provides process IDs from
PROCESS and SQLPROC.
