| 7 | <h1>Examples of LTTng use in the field</h1> |
| 8 | <p> |
| 9 | A few examples of successful LTTng users : |
| 10 | |
| 11 | <ul> |
| 12 | <li> Google are deploying LTTng on their servers. They want to use it to |
| 13 | monitor their production servers (with flight recorder mode tracing) |
| 14 | and to help them solve hard to reproduce problems. They have had |
| 15 | success with such tracing approach to fix "rare disk delay" issues and |
| 16 | VM-related issues presented in this article : |
| 17 | <ul> |
| 18 | <li> <a href="http://ltt.polymtl.ca/papers/bligh-Reprint.pdf">Linux Kernel |
| 19 | Debugging on Google-sized clusters at Ottawa Linux |
| 20 | Symposium 2007</a> |
| 21 | </ul> |
| 22 | <li> IBM Research have had problems with Commercial Scale-out applications, |
| 23 | which are being an increasing trend to split large server workloads. |
| 24 | They used LTTng successfully to solve a distributed filesystem-related |
| 25 | issue. It's presented in the same paper above. |
| 26 | |
| 27 | <li> Autodesk, in the development of their next-generation of Linux |
| 28 | audio/video edition applications, used LTTng extensively to solve |
| 29 | soft real-time issues they had. Also presented in the same paper. |
| 30 | |
| 31 | <li> Wind River included LTTng in their Linux distribution so their |
| 32 | clients, already familiar to Wind River own tracing solution in |
| 33 | VxWorks, car have the same kind of feature they have relied on for a |
| 34 | long time. |
| 35 | |
| 36 | <li> Montavista have integrated LTTng in their distribution for the same |
| 37 | reasons. It's used by Sony amongst others. |
| 38 | |
| 39 | <li> SuSE are currently integrating LTTng in their next SLES distribution, |
| 40 | because their clients asking for solutions which supports a kernel |
| 41 | closer to real-time need such tools to debug their problems. |
| 42 | |
| 43 | <li> A project between Ericsson, the Canadian Defense, NSERC and various |
| 44 | universities is just starting. It aims at monitoring and debugging |
| 45 | multi-core systems and provide automated and help user system behavior |
| 46 | analysis. |
| 47 | |
| 48 | <li> Siemens have been using LTTng internally for quite some time now. |
