    Tool: get_trace

    Use this as the primary tool to retrieve a single distributed trace from Google Cloud Trace. Traces provide a detailed view of the path of a request as it travels through your application's services. This is essential for understanding latency issues and debugging complex, multi-service workflows. This is often used as a follow on to list_traces to get full details on a specific trace.

    The following sample demonstrate how to use curl to invoke the get_trace MCP tool.

    Input Schema

    The request message for the GetTrace method.

    GetTraceRequest

    JSON representation 
     { 
 "projectId" 
 : 
 string 
 , 
 "traceId" 
 : 
 string 
 }
    Fields
    projectId

    string

    Required. ID of the Cloud project where the trace data is stored.
    traceId

    string

    Required. ID of the trace to return.

    Output Schema

    A trace describes how long it takes for an application to perform an operation. It consists of a set of spans, each of which represent a single timed event within the operation.

    Trace

    JSON representation 
     { 
 "projectId" 
 : 
 string 
 , 
 "traceId" 
 : 
 string 
 , 
 "spans" 
 : 
 [ 
 { 
 object (  TraceSpan 
 
) 
 } 
 ] 
 }
    Fields
    projectId

    string

    Project ID of the Cloud project where the trace data is stored.
    traceId

    string

    Globally unique identifier for the trace. This identifier is a 128-bit numeric value formatted as a 32-byte hex string. For example, 382d4f4c6b7bb2f4a972559d9085001d . The numeric value should not be zero.
    spans[]

    object ( TraceSpan )

    Collection of spans in the trace.

    TraceSpan

    JSON representation 
     { 
 "spanId" 
 : 
 string 
 , 
 "kind" 
 : 
 enum ( SpanKind 
)

 "name"

 :

 string 
 :

 ... 
 } 
 }
    Fields
    spanId

    string ( uint64 format)

    Identifier for the span. Must be a 64-bit integer other than 0 and unique within a trace. For example, 2205310701640571284 .
    kind

    enum ( SpanKind )

    Distinguishes between spans generated in a particular context. For example, two spans with the same name may be distinguished using RPC_CLIENT and RPC_SERVER to identify queueing latency associated with the span.
    name

    string

    Name of the span. Must be less than 128 bytes. The span name is sanitized and displayed in the Trace tool in the Google Cloud Platform Console. The name may be a method name or some other per-call site name. For the same executable and the same call point, a best practice is to use a consistent name, which makes it easier to correlate cross-trace spans.
    startTime

    string ( Timestamp format)

    Start time of the span in seconds and nanoseconds from the UNIX epoch.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .
    endTime

    string ( Timestamp format)

    End time of the span in seconds and nanoseconds from the UNIX epoch.

    Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z" , "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30" .
    parentSpanId

    string ( uint64 format)

    Optional. ID of the parent span, if any.
    labels

    map (key: string, value: string)

    Collection of labels associated with the span. Label keys must be less than 128 bytes. Label values must be less than 16 KiB. Some keys might have predefined meaning, and you can also create your own.

    For more information, see Cloud Trace labels .

    Timestamp

    JSON representation 
     { 
 "seconds" 
 : 
 string 
 , 
 "nanos" 
 : 
 integer 
 }
    Fields
    seconds

    string ( int64 format)

    Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be between -62135596800 and 253402300799 inclusive (which corresponds to 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z).
    nanos

    integer

    Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.
