ServiceWatch metric

CacheStore (DBaaS) sends metrics to ServiceWatch. The metrics provided by basic monitoring are data collected at 1‑minute intervals.

Reference

For instructions on how to view metrics in ServiceWatch, refer to the ServiceWatch guide.

Basic Metrics

The following are the basic metrics for the namespace CacheStore(DBaaS).

The indicators whose names are shown in bold below are the key metrics selected from the basic metrics provided by CacheStore(DBaaS). The key metrics are used to build service dashboards that are automatically created for each service in ServiceWatch.

Each metric provides guidance in the user guide on which statistical values are meaningful when viewing that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. In the service dashboard, you can view key metrics through primary statistical values.
