If it's so, these metrics(service level) seem not correct. Let's say there are two Clickhouse nodes, each node has its the number of connections, OTEL will scrap two places and forward to OAP, then, without specific downsampling process, in one minute, the data from each node would overlap and override each other. How is this processed now? -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
