It is very likely that you've lost a number of metrics, but this wholly depends on how many metrics were sent over the weekend to the fallen node. If this exceeds the 9 million you mention your queue size is, then you've lost the surplus of that number.
Ok so I've lost metrics for the fallen node right ? It's not an issue then because I have a copy on the other cluster.
correct, each node has an associated queue, so delivery to available nodes isn't affected by nodes that are down
Thank you for your quick answers. I use this case to thank you for your great work on this project.
Hello,
I have to relays receiving metrics in round robin. They are configured with a 9 million object queue each and the batch option is set with 2500 metrics. They both send data to two clusters with a replication factor of 1.
This weekend a graphite carbon node from one cluster went down until this morning. Can you tell me what is carbon-c-relay behavior when the queue were full of this node's metrics ? As it batches metrics, does it mean that regular metrics have been lost or is it a seperate queue ?
Thanks
