SAS SPD Server 4.5 provides
a performance monitoring server called spdsperf. SPD Server Performance
Server is an optional component and is not required for the normal
operation of SPD Server.
Note: SPD Server Performance Server
is currently not available for the Windows or Linux X64 platforms.
SPD Server Performance
Server gathers SPD Server process performance information and posts
it to the SPD
Server Management section of
the SAS Management Console application. The information consists
of memory and resource allocations by users, and SPD Server processes
that were spawned by an SPD Server name server. All SPD Server users
must connect to an SPD Server name server before their SPD Server
session is spawned. Each SPD Server name server owns a dynamic family
of subordinate SPD Server processes that SPD Server users and jobs
create and terminate.
The information that
is gathered by SPD Server Performance Server is stored in the SAS
Management Console. The SAS Management Console has a folder that is
reserved for SPD Server management. The
SPD Management folder is a child of the
Environmental Management folder in the SAS Management Console. When you expand the
SPD Management folder, the next to last utility is
SPD Process Profiler. Highlight the
SPD
Process Profiler utility to display the process information
table, which contains performance summary statistics. Each row in
the table provides information about a single SPD Server process that
was spawned on the SPD Server name server that resides on the specified
port ID (PID).
The SPD Process Profiler
displays information about memory and resource allocations. For this
reason, you can use the SAS Management Console to review which SPD
Server processes are occupying host computing resources, how the resources
are distributed across users and processes at a given point in time,
and whether the resource uses and distributions are appropriate for
your computing environment.
Not only can you display
performance summary statistics in the SAS Management Console application.
You can also configure the SPD Server Performance Server when you
launch it, to create text log files that can be saved locally on the
SPD Server host machine. SPD Server ships with a PERL utility called
process_perf_log that can parse the log that SPD Server Performance
Server created.
