Hi, LTTngTop is still work in progress and will remain that way for a long time, but the version in the PPA (or in the master branch in git) is perfectly usable for offline traces (traces recorded and replayed through LTTngTop).
The "live" branch is more experimental and requires patches in both Babeltrace and Lttng-tools (all documented in the README-LIVE file), but it worked at the time of Plumbers, I didn't have much time since then to rebase the branches. I am waiting for the release of Lttng-tools 2.1 (currently in RC) before merging those patches. After these patches are integrated, LTTngTop will be able to work live without any modifications, so directly reading traces in memory shared with the tracer. In the meantime we are working on replacing the "home made" state system in LTTngTop with a more generic one (which will be used also in LTTV), this will cleanup this part of the code and allow to store the state on disk. So in a near future we will be able to only read the state instead of the trace (once it has been generated), which will compress significantly the amount of data we need to keep in order to access the kind of statistics provided by LTTngTop. If you want to try LTTngTop, you can just install the package and follow the man page to record a trace with the right contexts, it should work as is. If you have any questions and/or feedback, please don't hesitate to ask. Thanks, Julien On 08/10/12 05:57 PM, McDermott, Andrew wrote: > I was wondering what the status of lttng top was.
