52 | This document is made of four parts : the first one explains how |
24070967 |
53 | to install LTTng and LTTV from sources, the second one describes the steps |
633bc4a3 |
54 | to follow to trace a system and view it. The third part explains |
c924c2c6 |
55 | briefly how to add a new trace point to the kernel and to user space |
633bc4a3 |
56 | applications. The fourth and last part explains how to create Debian or RPM |
57 | packages from the LTTng and LTTV sources. |
c924c2c6 |
58 | <p> |
24070967 |
59 | These operations are made for installing the LTTng 0.86 tracer on a linux 2.6.X |
c924c2c6 |
60 | kernel. You will also find instructions for installation of LTTV 0.12.x : the |
61 | Linux Trace Toolkit Viewer. |

242 | You must activate debugfs and specify a mount point. This is typically done in |
c8997124 |
243 | fstab such that it happens at boot time. If you have never used DebugFS before, |
244 | these operation would do this for you : |
c924c2c6 |
245 | |
c8997124 |
246 | <PRE> |
c924c2c6 |
247 | mkdir /mnt/debugfs |

c924c2c6 |
251 | |
c8997124 |
252 | <p> |
c924c2c6 |

259 | You need to load the LTT modules to be able to control tracing from user |
260 | space. This is done by issuing the following commands. Note however |
261 | these commands load all LTT modules. Depending on what options you chose to |
262 | compile statically, you may not need to issue all these commands. |
263 | |

c924c2c6 |
284 | If you want to have complete information about the kernel state (including all |
285 | the process names), you need to load the ltt-statedump module. This is done by |
286 | issuing the command : |
287 | |
c8997124 |
288 | <PRE> |
c924c2c6 |
289 | modprobe ltt-statedump |
c8997124 |

291 | <p> |
c924c2c6 |

293 | |
c8997124 |
294 | <PRE> |

c8997124 |
390 | <PRE> |
c924c2c6 |
391 | The tracing can be controlled from a terminal by using the lttctl command (as |
392 | root). |
393 | |
394 | Start tracing : |
395 | |
396 | lttctl -C -w /tmp/trace1 trace1 |
397 | |
398 | Stop tracing and destroy trace channels : |
399 | |
400 | lttctl -D trace1 |
401 | |
402 | see lttctl --help for details. |

c924c2c6 |
405 | (note : to see if the buffers has been filled, look at the dmesg output after |
406 | lttctl -R or after stopping tracing from the GUI, it will show an event lost |
407 | count. If it is the case, try using larger buffers. See lttctl --help to learn |
408 | how. lttv now also shows event lost messages in the console when loading a trace |
409 | with missing events or lost subbuffers.) |
410 | |
c8997124 |
411 | <li>Use text mode LTTV</li> |
c8997124 |
412 | <p> |
c924c2c6 |
413 | Feel free to look in /usr/local/lib/lttv/plugins to see all the text and |
414 | graphical plugins available. |
c8997124 |
415 | <p> |
c924c2c6 |
416 | For example, a simple trace dump in text format is available with : |
c8997124 |
417 | <PRE> |
c924c2c6 |
418 | lttv -m textDump -t /tmp/trace |
c8997124 |
419 | </PRE> |
c8997124 |
420 | <p> |
421 | See lttv -m textDump --help for detailed command line options of textDump. |
c8997124 |
422 | <p> |
c924c2c6 |
423 | It is, in the current state of the project, very useful to use "grep" on the |
424 | text output to filter by specific event fields. You can later copy the timestamp |
425 | of the events to the clipboard and paste them in the GUI by clicking on the |
426 | bottom right label "Current time". Support for this type of filtering should |
427 | be added to the filter module soon. |
428 | |
c8997124 |
429 | <li>Hybrid mode</li> |
c8997124 |
430 | <p> |
c924c2c6 |
431 | Starting from LTTng 0.5.105 and ltt-control 0.20, a new mode can be used : |
432 | hybrid. It can be especially useful when studying big workloads on a long period |
433 | of time. |
c8997124 |
434 | <p> |
c924c2c6 |
435 | When using this mode, the most important, low rate control information will be |
436 | recorded during all the trace by lttd (i.e. process creation/exit). The high |
437 | rate information (i.e. interrupt/traps/syscall entry/exit) will be kept in a |
438 | flight recorder buffer (now named flight-channelname_X). |
c8997124 |
439 | <p> |
c924c2c6 |
440 | The following lttctl commands take an hybrid trace : |
c8997124 |
441 | <p> |
c924c2c6 |
442 | Create trace channel, start lttd on normal channels, start tracing: |
c8997124 |
443 | <PRE> |
c924c2c6 |
444 | lttctl -C -w /tmp/trace2 -o channel.kernel.overwrite=1 trace2 |
c8997124 |
445 | </PRE> |
446 | <p> |
c924c2c6 |
447 | Stop tracing, start lttd on flight recorder channels, destroy trace channels : |
c8997124 |
448 | <PRE> |
c924c2c6 |
449 | lttctl -D -w /tmp/trace2 trace2 |
c8997124 |
450 | </PRE> |
451 | <p> |
c924c2c6 |
452 | Each "overwrite" channel is flight recorder channel. |

c8997124 |
454 | <li>Flight recorder mode</li> |
c8997124 |
455 | <p> |
c924c2c6 |
456 | The flight recorder mode writes data into overwritten buffers for all channels, |
457 | including control channels, except for the facilities tracefiles. It consists of |
458 | setting all channels to "overwrite". |
c8997124 |
459 | <p> |
c924c2c6 |
460 | The following lttctl commands take a flight recorder trace : |
c8997124 |
461 | <PRE> |
c924c2c6 |
462 | lttctl -C -w /tmp/trace3 -o channel.all.overwrite=1 trace3 |
