LTTngTop Julien Desfossez June 2015 Lttngtop is an ncurses interface for reading and browsing traces recorded by the LTTng tracer and displaying various statistics. As of now, the cpu usage, per file/process I/O bandwidth and perf counters are displayed. This release is the first one that handles live sessions as well as offline sessions. USAGE ----- The manpage located in the doc folder of this source tree documents the usage of LTTngTop. BUILDING -------- ./bootstrap (skip if using tarball) ./configure make make install DEPENDENCIES ------------ To compile Babeltrace and lttngtop, you need: gcc 3.2 or better libc6 development librairies (Debian : libc6, libc6-dev) (Fedora : glibc, glibc) glib 2.22 or better development libraries (Debian : libglib2.0-0, libglib2.0-dev) (Fedora : glib2, glib2-devel) libpopt >= 1.13 development libraries (Debian : libpopt-dev) (Fedora : popt) ncurses development libraries (Debian : libncurses5-dev) babeltrace = 1.2.4 development library (Debian : libbabeltrace-dev, libbabeltrace-ctf-dev) To use the local live tracing feature, you need: lttng-tools >= 2.4 lttng-modules >= 2.4 babeltrace = 1.2.4 For developers using the git tree: This source tree is based on the autotools suite from GNU to simplify portability. Here are some things you should have on your system in order to compile the git repository tree : - GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50) (make sure your system wide "automake" points to a recent version!) - GNU Libtool >=2.2 (for more information, go to http://www.gnu.org/software/autoconf/) If you get the tree from the repository, you will need to use the "bootstrap" script in the root of the tree. It calls all the GNU tools needed to prepare the tree configuration.
