Dear all,
I'd like to announce publication of Linux Kernel State Tracer (LKST) 1.3,
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,
(1)It is possible to change dynamically which events are recorded.
Users can obtain information about the events which they concern
only interesting events.
And it reduces the overhead of components which is not related
with a fault.
(2)It is possible to change each function invoked by each events.
A default function invoked by events is just recording occuring of the events.
But, if it is necessary, this function can be changed to another
function.
And LKST supports installing the function by using a kernel module
LKST also supports a maskset, which controls what kind of events should be
recorded, can be changed dynamically. For example, LKST usually traces
a few events for good performance, and when the kernel be in a particular
status, LKST can change a maskset to get more detail information.
(3)It is possible to create new buffers and change to one of them.
By changing to other buffer, Users can leave the information
which they want.
LKST binaries, source code and documents are available in the following site,
https://sourceforge.net/projects/lkst/

We prepared a mailing list written below in order to let users know
