# Metrics
The following Bigtable metrics are provided to Cloud Monitoring. For
best results, always use server-side metrics in conjunction with
[client-side metrics](https://docs.cloud.google.com/bigtable/docs/client-side-metrics-descriptions) for
performance debugging.
The "metric type" strings in this table must be prefixed
with `bigtable.googleapis.com/`. That prefix has been
omitted from the entries in the table.
When querying a label, use the `metric.labels.` prefix; for
example, `metric.labels.LABEL="VALUE"`.
