By default, applications such as SAS Information Map Studio, the SAS Information
Delivery Portal, and SAS Web Report Studio use SAS Pooled Workspace Servers to
query relational data. SAS Pooled Workspace Servers are configured to use server-
side pooling and load balancing.
a configuration in which the client application maintains a collection of reusable
workspace server processes. In releases prior to 9.2, client-side pooling was the only
method of configuring pooling for workspace servers.
For more information about pooling, see the SAS Intelligence Platform: Application
Server Administration Guide.
Logging and Monitoring for SAS Servers
The SAS Intelligence Platform uses a standard logging facility to perform logging for
SAS servers. The logging facility supports problem diagnosis and resolution,
performance and capacity management, and auditing and regulatory compliance. The
logging facility provides the following capabilities for servers:
• Log events can be directed to multiple destinations, including files, operating system
facilities, and client applications.
• For each log destination, you can configure the message layout, including the
contents, the format, the order of information, and literal text.
• For each log destination, you can configure a filter to include or exclude events
based on levels and message contents.
• For the metadata server, security-related events are captured, including
authentication events, client connections, changes to user and group information, and
• You can generate performance-related log events in a format that can be processed
by an Application Response Measurement (ARM) 4.0 server.
SAS Environment Manager provides web-based management, operation, and proactive
monitoring of servers on both the middle tier and the SAS server tier. Backed by Hyperic
technology from VMware, this application provides automatic resource discovery,
monitoring of remote systems, role-based dashboards, alerting, and visualization
In addition, you can use the server management features of SAS Management Console
to do the following:
• view server and spawner logs
• change logging levels dynamically without stopping the server
• quiesce, stop, pause, and resume servers and spawners
• validate servers and spawners and test server connections
• view information about current connections and processes
• view performance counters that provide statistics about activity that has occurred
since a server or spawner was last started
Server monitoring can also be performed using third-party products for enterprise
