| Description | The component element table provides a list of component
(operating system) services or processes that are elements of
an enterprise contact center application functional component.
Each entry identifies a single process that is a necessary
element of the functional component.
This table also provides a one-to-one mapping of entries to a
corresponding entry in IETF standard host and application MIB
tables. The HOST-RESOURCES and SYSAPPL MIBs expose tables
that provide additional instrumentation for software and
applications and for the processes that make up that software
or those applications. The HOST-RESOURCES-MIB entries in
'hrSWRunTable' and 'hrSWRunPerfTable' and the SYSAPPL-MIB
entries in 'sysApplElmtRunTable' have a one-to-one
relationship to entries in the component element table. The
entries in these standard MIB tables are solely or partially
indexed by the operating system process identifier (ID). The
process ID is an integer value that uniquely identifies a
single process that is currently running on the host. Entries
in the component element table maintain its process ID; this
value is used to relate the entry to a corresponding entry in
the referenced tables of HOST-RESOURCES-MIB and SYSAPPL-MIB.
Entries in these tables of the HOST-RESOURCES and SYSAPPL MIBs
expose similar information about each process; in some cases,
objects are duplicated. However, while the HOST-RESOURCES-MIB
lists processes with no further relationship, the SYSAPPL-MIB
relates these same processes to installed software packages
and the elements that make up those packages.
Entries in the component element table cannot be similarly
indexed as the referenced standard MIB tables because, should
the process terminate (expectedly or unexpectedly), the entry
would need to be removed from the table since its index or
process ID is thus unknown. This behavior diminishes the
agent's ability to express a component element's current
status since the entry no longer exists. However, to relate
this table to the referenced standard MIB tables, entries in
the component element table maintain the current process ID
of the element. This provides the one-to-one relationship
that allows the management station to drill down further on
each functional component and present instrumentation related
to each element of that component from these standard MIB
tables.
This table has a expansion relationship with the component
table; there will be one or many entries in this table that
relate to a single entry in the component table.
Because the set of elements of a contact center functional
component are finite and static, this table is constructed by
the SNMP agent at startup; entries cannot be added or deleted
at run time. The object values of each element entry may
change periodically if the run state of the process changes.
The SNMP agent will alter the RunID and Status object values
to reflect the correct process ID and run status of that
process. All objects in this table are read-only to the
management station. |
