Nikita Amelchev updated IGNITE-28919:
-------------------------------------
Fix Version/s: 2.19
> Add communication and discovery network test commands
> -----------------------------------------------------
>
> Key: IGNITE-28919
> URL: https://issues.apache.org/jira/browse/IGNITE-28919
> Project: Ignite
> Issue Type: Improvement
> Reporter: Nikita Amelchev
> Assignee: Nikita Amelchev
> Priority: Major
> Labels: ise
> Fix For: 2.19
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Replace the legacy communication IO test with management API commands.
> Preserve communication latency testing with clearer millisecond-based output,
> and add a new test for measuring message traversal through the
> {{TcpDiscoverySpi}} ring, including per-hop and total timings.
> h3. Communication SPI
> {code}
> $ control.sh --io-test communication --node-id
> 8f3c1d72-6a94-4b57-9e21-3d8f0a6c42b5
> Communication SPI test
> Source: srv-1 [id=8f3c1d72-6a94-4b57-9e21-3d8f0a6c42b5]
> Parameters: warmup=5000 ms | duration=30000 ms | threads=1 | payload=0 bytes
> Handling: system pool
> RTT:
> Target Samples Min, ms Avg, ms Max, ms
> srv-2 142851 0.028 0.087 4.106
> srv-3 142850 0.029 0.089 3.884
> Estimated one-way delivery*:
> Target Direction Min, ms Avg, ms Max, ms
> srv-2 Request 0 0.045 4
> srv-2 Response 0 0.042 3
> srv-3 Request 0 0.046 3
> srv-3 Response 0 0.043 3
> * One-way delivery uses OS wall-clock time and requires synchronized node
> clocks.
> RTT uses a monotonic clock. System-pool handling includes executor dispatch
> time.
> {code}
> h3. Discovery SPI
> {code}
> $ control.sh --io-test discovery
> TcpDiscoverySpi ring test
> Coordinator: srv-1 [id=8f3c1d72-6a94-4b57-9e21-3d8f0a6c42b5]
> Parameters: samples=10 | interval=100 ms | payload=100 bytes
> Full-ring latency:
> Samples Min, ms Avg, ms Max, ms
> 10 0.559 0.619 0.729
> Estimated per-hop delivery (ring order)*:
> From To Min, ms Avg, ms Max, ms
> srv-1 srv-2 0 0.000 0
> srv-2 srv-3 0 0.000 0
> srv-3 srv-1 0 0.000 0
> * Per-hop delivery uses OS wall-clock time and requires synchronized node
