Here we can see that 39/40 nodes received 1 extra message than expected.
Also, we see that node 16U*WqokQX missed some messages. At first glance, looks like this node can be involved in the problem.
Further analyzing the log messages, we are able to obtain two pieces of information in form of dataframes.
Every time a node receives a message, it logs a line like the following one:
NTC 2024-08-23 11:07:20.059+00:00 waku.relay received topics="waku node" tid=1 file=waku_node.nim:230 my_peer_id=16UWqokQX pubsubTopic=/waku/2/rs/66/0 msg_hash=0x40937c4863ac7cde6661f7c3efac79f79ee1185ac5670e8e44c178824d30d57e receivedTime=1724411240060182528 payloadSizeBytes=91022
With this information, we are able to construct the following dataframe:
