Meanings of Metric
| Memory usage | Means the real-time information on the cache size used by the user program. |
|---|---|
| Cache hit ratio | Means the ratio of the size of data called from the cache to the total size of data to be called when the user program is running. |
| Network traffic | Means the size of data exchanged between the cache portion and other services. |
| QPS | Means the quantity of query requests per second, i.e., Query Per Second |
| Data replacement ratio | Means the ratio of the quantity of data replaced in the cache with the data elimination mechanism to the total quantity of data in the cache |
| CPU usage | Means the ratio of CPU resources occupied by running program to the peak computing power of the CPU |
| Swap partition usage | Means the real-time information about the swap partition size used by the user program |
Operating Steps
- Click the "Cluster monitoring" tab to check whether the metrics of the entire cluster meet the requirements.
- Drag the scroll bar below to view the historical data, and click the cross symbol at the upper right corner to view the larger image. The value in the small image is sum for the historical data, and in the large image, you can choose the "Statistics", "Sampling cycle" and "Recent" data to be viewed, based on your needs.
- Click to open the "Node Monitoring" tab to check whether the metrics of each node meet the requirements. The user can select the node id to view the node.
