SQL queries to ODBC datasources for retrieval and display in table and chart views. subnetwork A configuration wherein a single IP network address is split up so it can be used on several interconnected local networks. Subnetworking is a local configuration; outside it appears as a single IP network. SUF See Situation Update Forwarder. summarization and pruning agent One of the Tivoli Monitoring base agents, the summarization and pruning agent is used to keep the data warehouse from growing too large by summarizing and pruning your stored historical data at intervals that you set. For every attribute group that has data collection configured, you specify how often to aggregate (summarize) data in the Tivoli Data Warehouse and the length of time to delete (prune) data from the warehouse. symbol Represents a variable that can be added to header or footer text for data views, expert-advice text, or query specification. The detailed attribute name is enclosed in dollar signs, such as $ORIGINNODE$, and resolves to the attribute's value. For Tivoli Enterprise Monitoring Server queries, == $NODE$ specifies the managed systems from which to retrieve data. For queries to be used in link target workspaces, you can create symbols for attributes using the $symbolname$ format. System Monitor Agent These agents were introduced with IBM Tivoli Monitoring V6.2.2 for nodes that run the desktop operating systems (Windows, Linux, UNIX). These agents operate only autonomously (that is, they run without a connection to a Tivoli Enterprise Monitoring Server) and pass SNMP trap data about operating system performance to an SNMP Event Collector such as IBM Tivoli Netcool/OMNIbus's MTTRAPD receiver. No other IBM Tivoli Monitoring agents or other components should be installed on the same node as a System Monitor Agent. The only exception to this rule is agents created with the Agent Builder tool for V6.2.2 or subsequent. System Service Monitors The IBM Tivoli Netcool/OMNIbus product provides System Service Monitors that support basic system-level monitoring of network components such as operating systems. In addition, OMNIbus provides ISMs (Internet Service Monitors) and ASMs (Application Service Monitors). Take Action A Tivoli Enterprise Portal dialog box from which you can enter a command or choose from a list of predefined commands. It also lists systems on which to effect the command, which is usually a response to an event. Take Action command A Take Action command allows you to send commands to your managed systems, either automatically, in response to a situation that has fired (that is, turned true), or manually, as the Tivoli Enterprise Portal operator requires. With Take Action commands, you can enter a command or select one of the commands predefined by your product and run it on any system in your managed network. Thus you can issue Take Action commands either against the managed system where the situation fired or a different managed system in your network. target libraries SMP/E-controlled libraries that contain the data installed from the distribution media. TCP/IP See Transmission Control Protocol/Internet Protocol. TDW See Tivoli Data Warehouse. telnet A terminal emulation program used on TCP/IP networks. You can start a telnet session with another system and enter commands that execute on that system. A valid user ID and password for that remote system are required. threshold A level set in the system at which a message is sent or an error-handling program is called. For example, in a user Glossary 281
