@WayneShen2 Could you add more details about this issue? For example, which metric is missing? What do you mean by missing historical data? Historical data is kept in Prometheus.
Seems like only Node Throughput data missing.
Thanks for the context. Yes, earlier we were using the node_volume_read_data
+ node_volume_write_data
query in the dashboard. However, to simplify the query, we have introduced a new metric called node_volume_total_data
. This new metric is equivalent to the previous approach, but since older releases did not include it, you are missing historical data in Prometheus.
Could you try the query below for this panel? You should see historical data as well new data with this query:
sum(node_volume_read_data{datacenter=~"$Datacenter",cluster=~"$Cluster",node=~"$Node"}) by (node) + sum(node_volume_write_data{datacenter=~"$Datacenter",cluster=~"$Cluster",node=~"$Node"}) by(node)
Thank you, @rahulguptajss
That is working as expect
verified in 24.08
