What is SAS Environment Manager?
SAS Environment Manager is a web-based administration
solution for a SAS environment. The application can administer, monitor,
and manage SAS resources, including administering the SAS Web Application
Server and monitoring SAS foundation servers. The application collects
and charts data on metrics for monitored resources, providing a comprehensive
view of resource health and operation. It also provides functions
such as auto-discovery of resources, monitoring of log events, and
reporting of alerts. Over the lifecycle of SAS 9.4, functions will
be added to extend SAS Environment Manager's capabilities as
a centralized administration application for all SAS products.
SAS Environment
Manager is based on VMWare’s Hyperic product, with customizations
and plugins to optimize the product specifically for a SAS environment.
Some terms and concepts used in SAS Environment Manager are different
than in other parts of SAS, but these are noted in this document.
The basic architecture
of SAS Environment Manager consists of an agent process running on
each platform in a SAS deployment that communicates to a central management
server. Agents monitor detected resources and periodically report
resource metrics back to the server. The server provides an interface
for interacting with those agents, managing the data collected by
the agents, distributing plugins, creating alerts and escalation procedures
based on collected metrics, and graphing the metrics provided through
the installed plugins.
There are five main
components to SAS Environment Manager:
agent
An agent is a software
process that runs on each platform (middle-tier and server-tier machine)
in a SAS deployment. The agent is responsible for tasks such as discovering
software components on its platform, gathering metric and availability
data for the platform and components, and performing resource control
actions. The agents communicate with the management server. Plugins
are used to provide the agents with the information needed to discover
SAS resources installed on a platform.
management server
The management server is responsible
for communicating with the agents. It collects information about items
such as discovered resources, metrics, and availability, and issues
control actions received from the SAS Environment Manager application.
Collected data is stored in the SAS Environment Manager database.
SAS Environment Manager database
The database is a Postgres
database that is a repository for all of the information about all
of the resources known to SAS Environment Manager. It uses the SAS
Web Infrastructure Platform Data Server, which is based on PostgreSQL.
After resources are discovered and added to your inventory, the database
stores data collected from the agents about the resources.
SAS Environment Manager application
The application is
the web-based interface to the SAS Environment Manager system. Resources
discovered by the agents and added to the inventory are displayed
and monitored. Metric and availability data collected by the agents
and stored in the database is displayed and charted. Events and metric
data are used to generate alerts. Control actions are sent back through
the management server to the agents to control resources on the platforms.
The application also includes a framework to add functions specific
to SAS, such as server, library, and user administration.
