Archived from groups: linux>debian>ports>ia64 (more info?)

What performance management tools are people using at the moment? All
the ones I tried are currently broken:
pfmon is no longer in Debian unstable
oprofile doesn't work against the current Debian kernel -- it
looks for an oprofile filesystem, which can be enabled only
for non-IA64 systems.
q-tools also fails, as the version of perfmon it relies on is
older than that in the current kernel.
The commercial tool caliper from HP also needs an older kernel and
libc-stdc++5

So what are people using?

Peter, I guess it would help with what type of information you are looking for. Are you looking for basic cpu/mem/disk information? Personally I have collection of sar scripts, and take the output and make pretty rrdtool graphs with it.

I'm looking for cache miss profiles, pipeline stalls, etc., in a new
app I'm porting to Itanium. I think I said, tools for the PMU ---
i.e., perfcounter/perfmon in the kernel, and
q-tools/pfmon/oprofile/papi/caliper in userspace.

>From my understanding tracing for the kernel stack on linux is pretty limited, and on IA64 it is even more limited. Sorry to say, I know tools for sparc, power5/6 and pa-risc, but no good kernel time profilers for IA64. Sad

http://lttng.org/content/download You might have some luck getting a hold of the maintains of LTTng, I heard rumors a few years ago of them having a IA64 tool that might help. I have no idea of its state.

Good luck!

I'm aware of the Linux trace project. It doesn't do what I want. I'm
looking for a gprof-like profile of an app, but counting
BE_BUBBLE_ALL etc., or L3-cache miss events instead of program counter
hits.


There used to be good tools in Debian -- q-tools was one ---
specifically for IA64. These appear to have bit-rotted with the kernel
changes from perfmon to perfmon2 to the current whatever it is.

What I'm asking, is, what is supposed to work now in Debian? I can
file bug reports against all of them I suppose Sad
