Hi @haruzheng
Typically, ""Invalid capture, analysis stopped. Reason: Duplicate counter alias(es) :"" happens when you select two or more counters in the capture that have the same combination of "title" and "name" string. For example, under the "Linux" category there is a "Interrupts: IRQ", likewise for most Cortex-XXX CPUs there is also an "Interrupts: IRQ" counter. If you select both, you will get this error, this is a known issue.
regarding your custom events, if they are for a PMU (such as CPU or interconnect) then you should only specify the "event" attribute. If the PMU has an additional Cycle counter that can be selected without being counted towards the counter limit specified by "count=4" then you should give it a counter="our_pmu_ccnt" attribute as well as an event attribute, otherwise it should just have the event attribute.

In my case are if i has counter
attr, i only to get our_pmu_cnt0
, no matter if i choose any one from 0 to 3.
So i confusing it.
So you think this not a issue?
Just remove counter
attr, it will mapping by event
attr? <- I just want to check this.
Thank you.

That is correct. For PMU's with multiple configurable "slots" in a counter set (in your case count=4, so 4 possible slots), the "counter" is generated dynamically by gatord, you only need to specify the "event" attribute and because the category has a "counter_set" then gatord will create 4 counter slots for you to configure your PMU events to.

Thank you.
Right, it is not a problem.
