Fixes #390
Motivation
There is no support for instrumentation. If for some reason the connection with network node breaks or is slow / not responding properly there is no way to easily find out the underlying issues.
Solution
Tracing outbound requests solves this problem. It tells how many of the requests made to
/block/statusand other endpoints were successful or failed and their P-latency.You can Enable instrumentation from config using flag
"enable_request_instrumentation": trueSet Otel collector url using
otel_collector_url:"localhost:4317"Any collector can be used I have tested with Signoz and Zipkin.
More context in #390
Implementation
We override fetcher's ApiClient with a traced ApiClient that generates tracing data for all outbound requests. Tracer package initialise and set a global trace provider that collects all of this data and exports it to collectors.
