(on_button_press_event): Delegate to Graph. (on_motion_notify_event, on_scroll_event): Modify "active" graph. * grapher/StapParser.cxx (findTaggedValue): New parsing helper function. (io_callback): Support new syntax where properties are attached to graph data and not the entire graph. * grapher/grapher.cxx (GrapherWindow): Don't set graph values. * grapher/Makefile.am: Add Graph.cxx. * testsuite/systemtap.examples/general/grapher.stp: New property syntax. --- testsuite/systemtap.examples/general/grapher.stp | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) (limited to 'testsuite/systemtap.examples/general') diff --git a/testsuite/systemtap.examples/general/grapher.stp b/testsuite/systemtap.examples/general/grapher.stp index 26d35aca..9079cb40 100644 --- a/testsuite/systemtap.examples/general/grapher.stp +++ b/testsuite/systemtap.examples/general/grapher.stp @@ -2,11 +2,13 @@ probe begin { -printf ("%%Title:CPU utilization\n"); -printf ("%%XAxisTitle:Time\n"); -printf ("%%YAxisTitle:Percent\n"); printf ("%%DataSet:cpu 100 00ff00 bar\n"); printf ("%%DataSet:kbd 75 ff0000 discreet\n"); +printf ("%%DataSet:pty 50 0000ff discreet\n"); +printf ("cpu %%Title:CPU utilization\n"); +printf ("cpu %%XAxisTitle:Time\n"); +printf ("cpu %%YAxisTitle:Percent\n"); + } # CPU utilization @@ -31,3 +33,11 @@ probe kernel.function("kbd_event") { if ($event_type == 1 && $value) printf("kbd %d %d\n", gettimeofday_ms(), $event_code) } + +probe kernel.function("pty_write") { + if (count > 0) + printf("pty %d %.5s\n", gettimeofday_ms(), buf) +} + + + -- cgit
