tracegen

An jaeger trace generator utility using predefined templates

Intended Usage

The generator can be used to define a bunch of traces (related or otherwise) using the handlebars template files. These templates can then be used to generate traces by substituting values that change for each trace without changing the structure defined in the template file. Variables that change in a trace data are typically

1. traceId
2. spanIds
3. startTime for each span

The examples simple-isolated-traces.handlebars and cross-referenced-traces.handlebars can be used as reference

Example

simple-isolated-traces.handlebars: has 2 unique trace structures with 3 spans each. The traces are not related to each other

Trace-1: A->B->C
Trace-2: A->[B,C]

cross-referenced-traces.handlebars has three traces with the first trace having references to trace2 and trace3

Variable format

t1.traceId -> traceId of firt trace
t1.s1 -> First spanId of first trace
t1.st1 -> startTime of first spanId of first trace

TODO

// Currently the tests only demonstrate constructing a Model.Batch from the handlebars template.

1. Hookup with apache JMeter or similar to generate based on JMeter load requirements
2. Evaluate and add more templates if needed
3. Add gRPC/HTTP sender to send the constructed traces to consumer
