Is there a way to see CPU utilisation per configured instance ?
Currently I only see one CPU utilisation no matter if 1 or 3 instances of Google Cloud Spanner are configured.
This would be interesting to get a glimpse if our data-structure balances load evenly.
Thanks, Christian
Today you can see the CPU usage of each instance by navigating to that instance's page in the console. Cloud Spanner doesn't separate the usage by node though, so you do only get a single figure for, say, a 3-node instance. Generally, Spanner will take care of balancing data across nodes to achieve even distribution.
Instance- and database-level utilization is also available through Google Stackdriver. Look for "spanner_instance" under the Metrics Explorer.
