Re: [tracecompass-dev] Questions about trace-server TSP API

Hi Patrick,

 

Is there any user guide for TSP API? Because I want to investigate how it works of all, like how to get the raw data, analysis and so on.

 

Best Regards,

Hi Patrick,

 

Thank you for your help. The trace can be opened after giving a correct location.

Hi Qing,

 

In your typeId value string there are spaces before and after. They should not be there.

 

But as far as I can tell this should not have mattered, it should select the most valid trace type automatically, the typeId is just a hint.

 

A valid Linux Kernel Trace is also a Generic CTF Trace.

 

I wonder if the problem is not that your TSP server is not finding a valid CTF trace at the given location. Is this location a folder that contains a "metadata" file?

Hi Guys,

 

Today I have tried to use TSP API of trace-server. But I got some problems on it.

 

API:

curl -X POST   http://localhost:8080/tsp/api/traces   -H 'accept: application/json'   -H 'cache-control: no-cache'   -H 'Content-Type: application/json'   -d '{"parameters": {"name":"trace1", "uri":"/home/chiq/kernel-trace", "typeID": " org.eclipse.linuxtools.tmf.core.type.ctf "}}'

 

Error code:

406

Error message:

No trace types found to match location /home/chiq/kernel-trace

 

There are two types of these traces:    1, Linux Kernel Trace

                                                                     2, Generic CTF Trace

 

What typeID are these traces of TSP API?

 

Thanks for your help.
