| The idea is to record the wire messages of the profiling agent and see how well they compress using different | ||
| compressors and what the CPU impact is. | ||
|
|
||
| To record the wire messages, you need to run the profiling agent with the `-bench-proto-dir` flag. | ||
| This will write the wire messages into the given directory. The directory will be created if it does not exist. | ||
|
|
||
| You can then use the `protobench` tool to compress the wire messages and see how well they compress and how much | ||
| CPU time it takes to compress them. | ||
|
|
||
| To run the profiling agent, first have a receiving endpoint, e.g. `devfiler` listening on localhost:11000. | ||
| Then run the profiling agent with the `-bench-proto-dir` flag: | ||
| ```shell | ||
| sudo ./opentelemetry-ebpf-profiler -bench-proto-dir=/tmp/protobuf -collection-agent=127.0.0.1:11000 -disable-tls | ||
| ``` | ||
| The wire messages are written to `protobuf/`, one file per message. | ||
|
|
||
| To compress the wire messages and generate a bar chart, run the `protobench` tool: | ||
| ```shell | ||
| cd tools/protobench | ||
| go run ./... -bench-proto-dir=/tmp/protobuf -output-file=results.png | ||
| ``` | ||
| If you don't see any errors, the tool will generate a PNG file with a bar chart showing the compression ratio and | ||
| compression time for each compressor. | ||
| The extension `.csv` can be used to generate a CSV file with the raw data instead of a PNG file. | ||
| No `-output-file` flag will display the results in the terminal. | ||
|
|
||
| Of course, you can also use the `protobench` tool to compare compression of any other files. | ||
|
|
