This is a development testing cli tool meant to stress the zipkin telegraf plugin.
|
|
It writes a specified number of zipkin spans to the plugin endpoint, with other
|
|
parameters which dictate batch size and flush timeout.
|
|
|
|
Usage as follows:
|
|
|
|
`./stress_test_write -batch_size=<batch_size> -max_backlog=<max_span_buffer_backlog> -batch_interval=<batch_interval_in_seconds> -span_count<number_of_spans_to_write> -zipkin_host=<zipkin_service_hostname>`
|
|
|
|
Or with a timer:
|
|
|
|
`time ./stress_test_write -batch_size=<batch_size> -max_backlog=<max_span_buffer_backlog> -batch_interval=<batch_interval_in_seconds> -span_count<number_of_spans_to_write> -zipkin_host=<zipkin_service_hostname>`
|
|
|
|
However, the flag defaults work just fine for a good write stress test (and are what
|
|
this tool has mainly been tested with), so there shouldn't be much need to
|
|
manually tweak the parameters.
