Dear all,
I'd like to announce publication of Linux Kernel State Tracer (LKST), which is a tracer for Linux kernel. LKST's main purpose is debugging, fault analysis and performance analysis of enterprise systems. For the purpose, LKST has these features, - It is possible to change dynamically which events are recorded. Developers can obtain information about the events which they concern only interesting events. And, It reduces the overhead of components which is not related with trouble. - It is possible to change each handlers related each events. A default handler of all events is just recording the events. But, if it is necessary, default handler can be changed. This function can be used as following, +Notify user processes when the handler detects abnormal status. +Change a maskset,which controls what type of events should be recorded, dynamically by the handler. -> The system can usually run with a few events trace for the cause of good performance. And, when the handler detects abnormal status, it can change a maskset to get more detail information.
LKST binaries, source code and documents are available in the following site, https://sourceforge.net/projects/lkst/ or http://oss.hitachi.co.jp/sdl/english/lkst.html (now updating)
I'm afraid misunderstanding so I add attention.
- This release is still BETA because some of features are not implemented. - Implementation of each trace points is not final but tentative. We started to improve this interface, and it will be included this feature in the next release (which will be by end of March in the next year).
We prepared a mailing list written below in order to let users know updates of LKST.
