Single Engine Summary

Several views show historical and current performance metrics for a single engine, including the number of processes running, threads, history of memory utilization, and trend graphs of memory utilization. In this display, when an engine is Stopped the engine name is appended with (X), the background color is light red and Uptime is zero.

Note: Clicking the Processes button in the Title Bar takes you to the All Processes Heatmap . Clicking the JVM button, which is automatically enabled when a JMX connection is defined for the engine, takes you to the JVM CPU/Mem Summary display. See Enable Monitoring Via JMX for more information on enabling a JMX connection.

Filter By: The display might include these filtering options:
	Filter:	Choose a filter to show data for in the display. By default, the Filter: drop-down menu only contains the No Filter option. To create your own filtering options, see Creating Customized Filters in the User’s Guide.
	Server:	Choose a server to show data for in the display.
	Engine:	Choose an engine to show data for in the display. An engine is not running when the engine name is appended with (X).
Fields and Data
	Engine Information
		Status	ACTIVE	The BW microagent is providing live data and the engine is assumed active.
			SUSPENDED	This state is reported by the BW microagent.
			STANDBY	This state is reported by the BW microagent.
			STOPPING	This state is reported by the BW microagent.
			STOPPED	This state is reported by the BW microagent.
			LIMITED	Live data has been received from TIBCO, but deployment data from the custom RTView MicroAgent has not been received.
			EXPIRED	The associated server for the engine is currently in an EXPIRED state and is unavailable or stopped sending data.
		Uptime	Days hours and minutes since the engine was started.
		CPU%	Percent of server CPU used by engine.
		Memory%	Available physical memory remaining (in MB).
		Threads	Number of threads used by this engine
		Max Heap MB	Maximum heap allocated to this engine for the JVM.
	Error Counts
		Total	Total errors accumulated by this engine.
		Current	Number of errors accumulated this update cycle.
	Process Counts
		Total	A BW Engine runs processes by creating instances of process definitions and making them active. A given process instance has a lifetime during which it may be suspended, swapped, queued, etc. until it is either completed or aborted. The Total value is calculated using the Hawk method named GetProcessDefinitions that returns statistics about the instances of each process definition including cumulative counts of completed, aborted, suspended, etc.
		Running	Total number of running process instances. This number is calculated using the Hawk method named GetProcessCount. It is displayed in the Monitor Engines Table as RunningProcesses. The trend below displays the same value over time as Running Procs.
	Alerts Indicates the greatest severity level and the number of open Engine, Process, and Activity alerts for the selected engine. Values range from 0 to 2, where 2 is the greatest Severity: One or more alerts exceeded their ALARM LEVEL threshold. One or more alerts exceeded their WARNING LEVEL threshold. No alert thresholds have been exceeded. Click on the alert indicator to display the BW Engine - Tables display, which contains a table listing the current alerts for the selected engine.
		Engine	Number of engine alerts and the most critical alert state for the engine: Red indicates that one or more metrics exceeded their ALARM LEVEL threshold. Yellow indicates that one or more metrics exceeded their WARNING LEVEL threshold. Green indicates that no metrics have exceeded their alert thresholds.
		Process	Number of process alerts and the most critical alert state for the engine: Red indicates that one or more metrics exceeded their ALARM LEVEL threshold. Yellow indicates that one or more metrics exceeded their WARNING LEVEL threshold. Green indicates that no metrics have exceeded their alert thresholds.
		Activity	Number of activity alerts and the most critical alert state for the engine: Red indicates that one or more metrics exceeded their ALARM LEVEL threshold. Yellow indicates that one or more metrics exceeded their WARNING LEVEL threshold. Green indicates that no metrics have exceeded their alert thresholds.
	Heatmap Shows processes organized by Server/Engine where Size = Creation Count and Color = Average Execution. Click on a node to drill down to a specific engine.
	Trend Graphs
		Log Scale	Select to enable a logarithmic scale. Use Log Scale to see usage correlations for data with a wide range of values. For example, if a minority of your data is on a scale of tens, and a majority of your data is on a scale of thousands, the minority of your data is typically not visible in non-log scale graphs. Log Scale makes data on both scales visible by applying logarithmic values rather than actual values to the data.
		Base at Zero	Select to use zero (0) as the Y axis minimum for all graph traces.
		Time Range	Select a time range from the drop down menu varying from 2 Minutes to Last 7 Days, or display All Data. To specify a time range, click Calendar . By default, the time range end point is the current time. To change the time range end point, click Calendar and select a date and time from the calendar or enter the date and time in the text field using the following format: MMM dd, YYYY HH:MM. For example, Aug 21, 2011 12:24 PM. Use the navigation arrows to move forward or backward one time period. NOTE: The time period is determined by your selection from the Time Range drop-down menu. Click Restore to Now to reset the time range end point to the current time.
