STAP(1) General Commands Manual STAP(1)NAMEstapgraph - systemtap grapherSYNOPSISstapgraph [ OPTIONS ] FILENAME [ ARGUMENTS ] stapgraph [ OPTIONS ] - [ ARGUMENTS ] stapgraph [ OPTIONS ] -e SCRIPT [ ARGUMENTS ]DESCRIPTIONThe stapgraph program is a simple frontend to stap that produces graphs from the output of stap scripts. This manual corresponds to version 1.7.OPTIONSstapgraph accepts all options accepted by stap. They are passed through to the stap process running the script or probe points.USER INTERFACEThe script that produces results can be started from a dialog within the program, in addition to being launched using the program's command line arguments. This dialog allows arguments to be passed to stap and to the script. When running, a mouse left click on a graph pauses the display of data, even though it is still collected by the program. Dragging the mouse scrolls the graph backwards and forwards in time; clicking the displayed pause button restarts the display of new data. The scroll wheel can be used to zoom in and out on the graph.SCRIPT OUTPUT SYNTAXScripts can output Comma Separated Values (CSV) which will be interpreted by stapgraph. The first value is the X coordinate of the graph, usually a time value. stapgraph assumes that this value is constantly increasing. A different syntax allows the script to specify many details of the graph's appearance. %DataSet: DATA-SET-NAME SCALE COLOR GRAPHSTYLE The data set name identifies a data set that will be emitted by the script. "SCALE" is the overall vertical scale of the graph for this data set. "COLOR" is a red-green-blue hex color. "GRAPHSTYLE" is one of bar - a traditional bar graph dot - plotted points discreet - An event style timeline that records that an event happened at a certain time. %Title: TITLE A title for the whole graph. %XAxisTitle: TITLE The legend for the X axis %YAxisTitle: TITLE The legend for the Y axis. %YMax: MAX VALUE The maximum value displayed on the graph.GRAPH DATADATA SET TIME VALUE Each data point that is to be plotted is tagged with the data set name, followed by the time and value of the point.SEE ALSOstap(3stap), staprun(3stap),BUGSUse the Bugzilla link off of the project web page or our mailing list. http://sourceware.org/systemtap/,<systemtap@sourceware.org>.
