Re: [tracecompass-dev] Viewing custom events in a timeline 
Hi Patrick,

as a matter of fact, I *don't* see the analysis at all under the trace.
I only see the "Tmf Statistics Analysis under there".

I tried having a look at the example under:
https://github.com/tracecompass/xml-analysis-example
where the only difference is that I don't "open" the trace, but I rather import it instead, because it comes from a custom Text parser (as opposed as from LTTNG). Actually, I also tried "opening" it and then selecting the trace type as my custom parser, but it still makes no difference.
What's funny is that the states are correctly visible on the "State System Explorer", so the analysis seems to work correctly. It's just the view (and the analysis under the trace, for that matter) that's not present.
Also manually opening "XML Time Graph View" does not seem to make a difference. Moreover, I noticed that after renaming the <stateProvider version="0" id="org.eclipse.tracecompass.request.analysis"> and re-importing the XML analysis file, the system still keeps creating a supplementary file by the old name. So I also tried wiping out the ~/.tracecompass directory and staring all over again, but still no luck. 

This is really driving me crazy...
BTW, I'm running Tracecompass 1.0.0 as a self-contained application started with:
./trace-compass/tracecompass -vm /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java 

Any bit of help would be highly appreciated!

Thank you,
Gerlando

Hi Gerlando,

First the timeGraphView id has to be unique, I'm not sure if the one
you're using is clashing with something else.

If you have only one XML-defined view you might have some luck by
opening LTTng > XML Time Graph View. But all the XML-defined time graph
views compete for this single view, it's not a fully correct
implementation yet...

Normally you would see your XML-defined view under the analysis, under
the trace in the Project Explorer. The view will show up there only once
the trace is opened. Then you open the view by double-clicking on it in
the Project Explorer.

    Hi Patrick, Matthew,

    thank you for your kind answers. Sorry for the late reply but I'm
    sort of doing this in my spare time.

    It all seems quite interesting but I don't exactly know what I'm
    looking for, so I'm playing with it one step at a time here.
    I somehow managed to start parsing the log files and get some events
    visible in the state system explorer.
    One question I actually do have, though: how can I open the time
    graph view I defined in the analysis file?

         <timeGraphView
    id="org.eclipse.linuxtools.tmf.analysis.xml.ui.views.statesystem">
             <head>
                 <analysis id="my.test.state.provider" />
                 <label value="My Sample XML View" />
             </head>
             <!-- StateValues -->
             <definedValue name="The process is running" value="100"
    color="#118811" />
             <definedValue name="Critical section" value="101"
    color="#881111" />
             <definedValue name="Waiting for critical section"
    value="102" color="#AEB522" />

             <!-- Control Flow View -->
             <entry path="Tasks/*">
                 <display type="self" />
             </entry>
         </timeGraphView>


    After I import it through "Import XML analysis", I was expecting it
    to show up under View / Show View, but I don't. I also checked that
    <analysis id="my.test.state.provider" /> matches <stateProvider
    version="0" id="my.test.state.provider">.

    Is there any way to enable debug/verbose output when importing XML
    file? This all happens in a very (disturbingly) silent way...

    And I'm probably missing something stupid...

    Thank you so much!

        Hi Gerlando,

        You don't need to have your source trace in CTF format.
        Although, if you
        do, it would probably be faster to process (which matters only
        if your
        trace is large), excluding the one-time conversion cost.

        You can create a custom parser for your source trace directly
        from a UI
        wizard, if it is in text or XML format:

        http://archive.eclipse.org/tracecompass/doc/stable/org.eclipse.tracecompass.doc.user/Trace-Compass-Main-Features.html#Custom_Parsers

        If your trace is neither text, XML or CTF, you would probably
        have to
        create your own trace type and parser as a plug-in extension in
        Java code:

        http://archive.eclipse.org/tracecompass/doc/org.eclipse.tracecompass.doc.dev/Implementing-a-New-Trace-Type.html#Implementing_a_New_Trace_Type


        You can then create your own state system and custom view based
        on it
        using data-driven analysis by writing an XML file:

        http://archive.eclipse.org/tracecompass/doc/stable/org.eclipse.tracecompass.doc.user/Data-driven-analysis.html#Data_driven_analysis

        Marc-Andre has made a presentation at EclipseCon 2015 which has an
        example of what you would need to do:

        https://www.eclipsecon.org/na2015/sites/default/files/slides/EclipseConAmerica2015.pdf
        (starting at page 25)

        Let us know if you need any more help, or if you have comments or
        suggestions after going through the process.

             Hi,

             I am currently trying to analyze the behavior and
        performance of a
             system under different configurations and circumstances.
             What I have is a series of events (start/stop) relative to
        several
             (~200) separate "entities" which I would like to see
        plotted in a
             timeline: Kind of like the timeline you see on the
        "Network" tab of
             the Developer Tools under Firefox, where you see how long
        each HTTP
             request lasts and how it overlaps with the others.
             Or like the "Control Flow" view in Tracecompass, except
        each row is
             *NOT* a linux process/thread, rather an internal "entity".
        So the
             data shall not come from LTTNG traces, rather from
        external, custom
             data.
             I suppose I could either:
             a) post-process a log file (by writing some translation
        script), so
             to generate some CTF trace, "faking" processes with my own
        entities, or
             b) instrument the code itself so to generate LTTNG-UST events.

             Any ideas how I could achieve this? Just some hint on where
        to start...

             Thank you so much!
