A Tair (Redis OSS-compatible) cluster instance distributes data across multiple nodes. Viewing per-node metrics — CPU utilization, memory usage, and number of keys — lets you determine whether a performance issue is isolated to a single node or affects the cluster as a whole.
Prerequisites
Before you begin, ensure that you have:
A Tair cluster instance
Access to the Tair console
View node metrics
Log on to the console and go to the Instances page. In the top navigation bar, select the region where your instance resides, find the instance, and click the instance ID.
In the left-side navigation pane, click Performance Monitor.
Click the Data Node tab.
Filter nodes to view the changes in the metrics of each node in a specific period of time.
