Not getting all bigtable metrics

[mystycs]

I have a question about stackdriver_exporter. I am trying to get out Bigtable metrics into Prometheus. Currently, I am only getting the following metrics below:

stackdriver_bigtable_cluster_bigtable_googleapis_com_cluster_cpu_load stackdriver_bigtable_cluster_bigtable_googleapis_com_cluster_cpu_load_hottest_node stackdriver_bigtable_cluster_bigtable_googleapis_com_cluster_disk_load stackdriver_bigtable_cluster_bigtable_googleapis_com_cluster_node_count stackdriver_bigtable_cluster_bigtable_googleapis_com_cluster_storage_utilization stackdriver_bigtable_cluster_bigtable_googleapis_com_disk_bytes_used stackdriver_bigtable_cluster_bigtable_googleapis_com_disk_storage_capacity stackdriver_bigtable_table_bigtable_googleapis_com_table_bytes_used

For some reason, I am not getting read/write/latency information. Am I missing something?

These are my values of data im trying to get.

 - name: STACKDRIVER_EXPORTER_MONITORING_METRICS_TYPE_PREFIXES
              value: "bigtable.googleapis.com"
