I have two sites with a cluster of two nodes each of the sites, with replication factor 2.
The goal is to monitor the XDR shipping performance and trying to compare the available metrics: xdr_ship_success, client_write_sucess, dlog_logged, xdr_throughput, etc.
If possible, I’d like to see the performance at the level of node first, and then of cluster and of global.
I found that:
- client_write_success includes all records from its local (site 1) and remote (from site 2): is there any way to know how many of them are from local or remote?
- dlog_logged looks like summing up all the records to ship from the two nodes of a cluster in site 1: is there any way to know how many of them is from each node?
Especially, I’m focusing on the node-level xdr performance. Is it doable based on these metrics, or can anyone suggest any other way?
Any good articles on this issue?
