MutableFire opened a new pull request, #1772: URL: https://github.com/apache/cloudberry/pull/1772
Adds a contrib extension `gp_interconnect_stats` to provide cumulative interconnect (IC) statistics for monitoring network traffic between segments. Based on the implementation from Greenplum ([open‑gpdb/gpdb#109](https://github.com/open-gpdb/gpdb/pull/109)). Creates the following views: * `gp_interconnect_stats` — aggregated statistics across all segments; * `gp_interconnect_stats_per_segment` — per‑segment statistics; * `gp_interconnect_stats_per_segment_per_host` — statistics grouped by host and segment. **Metrics description:** * `totalRecvQueueSize` — receive queue size sum when main thread is trying to get a packet. * `recvQueueSizeCountingTime` — counting times when computing `totalRecvQueueSize`. * `totalCapacity` — the capacity sum when packets are tried to be sent. * `capacityCountingTime` — counting times used to compute `totalCapacity`. * `totalBuffers` — total buffers available when sending packets. * `bufferCountingTime` — counting times when computing `totalBuffers`. * `activeConnectionsNum` — the number of active connections. * `retransmits` — the number of packet retransmits. * `mismatchNum` — the number of mismatched packets received. * `crcErrors` — the number of CRC errors. * `sndPktNum` — the number of packets sent by sender. * `recvPktNum` — the number of packets received by receiver. * `disorderedPktNum` — disordered packet number. * `duplicatedPktNum` — duplicate packet number. * `recvAckNum` — the number of ACKs received. * `statusQueryMsgNum` — the number of status query messages sent. -- This is an automated message from the Apache Git Service.
