- Data stored: The amount of data stored in the instance's cluster. This metric reflects the fact that Cloud Bigtable compresses your data when it is stored.
- Read requests: The number of random reads and scan requests per second.
- Write requests: The number of write requests per second.
- Read bandwidth: The number of uncompressed bytes per second that were read.
- Write bandwidth: The number of uncompressed bytes per second that were written.
- Error rate: The percentage of all requests that failed on the Cloud Bigtable server side.
- CPU usage: The amount of CPU being used ("Cluster CPU usage") and the maximum amount of CPU available ("Cluster CPU limit").
- Disk load: The total utilization of HDD disks across all of the nodes in the instance's cluster. Available only for HDD clusters.
You can view each of these metrics over a period ranging from the past 1 hour to the past 30 days.
To view metrics for a Cloud Bigtable instance:
- Go to the Google Cloud Platform Console.
- Open the list of your existing instances.
Click the name of the instance you want to view. The Cloud Platform Console displays a chart showing the amount of data stored over the past four days. If there is no data available for this time period, the chart will be empty.
To view a different metric, click Data stored and choose the metric you want to view.
To view a different time period, click one of the time periods above the top of the chart.
