Thread-topic: [tracecompass-dev] Problems importing simple values from

Hi Joerg,

Few things:

1) Your parser currently does not handle timestamps correctly. In the editor in Trace Compass, you can select the type of the group to be "TimeStamp". Then, on the place where you have currently specified the time stamp, you can specify the format for the output format, that is, how it will show in your graphs. (e.g. hh:mm:ss:SSSSSS).

2) For your analysis to show up in below your trace, I had to specifcy the trace type as: <traceType id="custom.txt.trace:CSV:MyDebugTrace"/> (but I may not be on the latest release)

3) In this case, the "eventName" of your eventHandler should correspond to a the name of your tracing as defined in your parser, in this case "MyDebugTrace"

4) In the event handler, to track only the uservalue, you don't need the valueid field. Furthermore, the uservalue should be of type "eventField" since you want to show a variable, rather than a constant.

There is another argument you can use to force the field to be read as int, which is forcedType="int"

5) In the view definition, the display value should refer to one of the values specified in the event handler, or should just show everything (display type="self")

See below for a revised version of your parser, analysis and view definition (don't forget to change your parser too):

parser:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<TimeStampOutputFormat>hh:mm:ss:SSSSSS</TimeStampOutputFormat>

<RegEx>([0-9.]*),UserValue,Id=(\d+),Value=(\d+)\S*</RegEx>

</InputLine>

</Definition>

</CustomTxtTraceDefinitionList>

analysis:

<?xml version="1.0" encoding="UTF-8"?>

<head>

</head>

<!--<stateAttribute type="eventField" value="ValueId" />

</stateChange>

</eventHandler>

</stateProvider>

<head>

</head>

<!--<display type="constant" value="value" />

</entry>

</xyView>

</tmfxml>

Kind regards,

Robbert

Hi Robbert,

thank you for your hints. I alread read that docs and could get my task switch logs into a timeGraphView. But I have no Idea how to
configure the a stateProvider for a kind of value "pass through" to a XY chart.

Here is my current test environment:

input Log data:
002.3,UserValue,Id=1,Value=0
005.2,UserValue,Id=1,Value=100
008.0,UserValue,Id=1,Value=120
010.0,UserValue,Id=2,Value=1

The parser:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<CustomTxtTraceDefinitionList>

<Definition category="CSV" name="MyDebugTrace">
<TimeStampOutputFormat>Tm.SS</TimeStampOutputFormat>
<InputLine>
<Cardinality max="2147483647" min="0"/>
<RegEx>([0-9.]*),UserValue,Id=(\d+),Value=(\d+)\S*</RegEx>
<EventType>EvUserValue</EventType>
<InputData action="" format="Tm.SS" name="Timestamp" tag="TIMESTAMP"/>
<InputData action="" format="" name="ValueId" tag="OTHER"/>
<InputData action="" format="" name="UserValue" tag="OTHER"/>
</InputLine>
<OutputColumn name="Timestamp" tag="TIMESTAMP"/>
<OutputColumn name="ValueId" tag="OTHER"/>
<OutputColumn name="UserValue" tag="OTHER"/>
</Definition>
</CustomTxtTraceDefinitionList>

.. and the analysis XML (not working):

<?xml version="1.0" encoding="UTF-8"?>
<tmfxml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../org.eclipse.tracecompass.tmf.analysis.xml.core/src/org/eclipse/tracecompass/tmf/analysis/xml/core/module/xmlDefinition.xsd">

    <stateProvider version="0" id="org.eclipse.tracecompass.uservalue.analysis">
        <head>
            <traceType id="mytrace:CSV:MyDebugTrace" />
            <label value="My TraceLog Analysis" />
        </head>

        <eventHandler eventName="EvUserValue">
            <stateChange>
                <stateAttribute type="constant" value="UserValues" />
                <stateAttribute type="eventField" value="ValueId" />
                <stateValue type="int" value="UserValue" />
            </stateChange>
       </eventHandler>
    </stateProvider>

    <xyView id="my.test.xy.chart.view">
        <head>
            <analysis id="org.eclipse.tracecompass.uservalue.analysis" />
            <label value="User value XY view" />
        </head>

        <entry path="UserValues/*">
            <display type="constant" value="value" />
            <name type="self" />
        </entry>
    </xyView>

</tmfxml>

What I want is simply track the value "UserValue" from the Log entries at a XY chart over the time.

kind regards,
Joerg
