Empty test configuration (empty/)
|
|
=================================
|
|
|
|
The 'empty' test is a minimal configuration that loads the OTel filter without
|
|
defining any scopes, events or groups. The instrumentation block contains only
|
|
the config directive pointing to the YAML pipeline definition.
|
|
|
|
This configuration verifies that the filter initializes and shuts down cleanly
|
|
when no telemetry is configured. It exercises the full YAML parsing path
|
|
(exporters, processors, readers, samplers, providers and signals) without
|
|
producing any trace, metric or log-record data.

Files
|
|
-----
|
|
|
|
empty/otel.cfg OTel filter configuration (instrumentation only)
|
|
empty/haproxy.cfg HAProxy frontend/backend configuration
|
|
empty/otel.yml Exporter, processor, reader and provider definitions
|
|
|
|
|
|
Events
|
|
------
|
|
|
|
No events are registered. The filter is loaded and attached to the frontend
|
|
but performs no per-stream processing.
|
|
|
|
|
|
YAML pipeline
|
|
-------------
|
|
|
|
Despite the empty filter configuration, the otel.yml file defines a complete
|
|
pipeline with all three signal types to verify that the YAML parser handles
|
|
the full configuration without errors:
|
|
|
|
Signal Exporter Processor / Reader
|
|
-----------------------------------------------------------
|
|
traces exporter_traces_otlp_http processor_traces_batch
|
|
metrics exporter_metrics_otlp_http reader_metrics
|
|
logs exporter_logs_otlp_http processor_logs_batch
|
|
|
|
Additional exporter definitions (otlp_file, otlp_grpc, ostream, memory,
|
|
zipkin, elasticsearch) are present in the YAML but are not wired into the
|
|
active signal pipelines.
|
|
|
|
|
|
Running the test
|
|
----------------
|
|
|
|
There is no dedicated run script for the empty configuration. To run it
|
|
manually from the test/ directory:
|
|
|
|
% /path/to/haproxy -f haproxy-common.cfg -f empty/haproxy.cfg
