[ltt-dev] how do I see symbol name for the function address in trace data

[Ming Lei]

Hi,

I collected data thru lttng and used lttv text mode, here is one example that I cannot see the symbol name for the function even I enabled KALLSYMS in kernel config file. I would like to see the function name in place of 0x401aa028, there is also needs to show the function name within kernel modules.

kernel.timer_set: 197.364192652 (/usr/local/src/linux-ws/lttdata/tmp.mm/trace1/kernel_0), 0, 0, swapper, , 0, 0x0, SOFTIRQ { expires = 4293900685, function = 0x401aa028, data = 0 }

Second question is:
How do I disable a channel? I used ltt-armall and it enabled all the traces. I want to disable a channel, can I do it?

Thanks
Ming
