RE: [linuxtools-dev] eclipse lttng viewer vs. lttv-gui

["Vestal Richard-B15972" <B15972@xxxxxxxxxxxxx>]

Hi Alvaro,

 

Thanks for the response.

 

I have filed the following bugs with the logs attached:

 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=311738

https://bugs.eclipse.org/bugs/show_bug.cgi?id=311742

 

For your swapper process not showing up, look at the constructor for LttngProcessState.  The first constructor is not assigning the traceId.  When I made that change, the swapper process started showing up.

 

Thanks,

 

n  Rick

Hello,
The file format should not be an issue for the representation of the states, I have tried a couple of files in 2.3 format and detected some differences but far less than with your file.

I.e. in one of the files I tried with 380 processes,
the only UNNAMED process was the swapper while lttv was able to resolve the name.

There were 2 out of 380 processes with a birth time of 0.

We will look into these differences and align with lttv,

There is no specific bug to track the differences as mentioned in your e-mail below,

Please file a bug so we can track the progress on it.

In order to have a common ground to discuss it, please submit the traces. If they are very large please e-mail me directly so I can fetch the logs.

Best Regards
/Alvaro

Hi,

 

I recognize that the lttng viewer for eclipse is at the .5 state, but here are some questions that relate to its current functionality.  Please let me know if I can find this information out somewhere else (bug database?):

 

We are loading the same trace file into the eclipse viewer as we are into the LTTV viewer and are seeing differences between them.  For instance:

 

-          The time values (both birth and nanos) are 0 for many entries (>90%) in eclipse but they almost all have values in the lttv viewer (The swapper process has 0 values in LTTV).

 

-          The number of events is different across the two.  There are many UNNAMED processes in the Eclipse viewer.

 

We are running on 2.3 traces.  Would this be an issue with the trace format?

 

Thanks,

 

n  Rick
