ApsaraDB for Redis supports a variety of performance metrics. You can query the monitoring data of an ApsaraDB for Redis instance during a specified period of time in the previous month. This help you gain insights into the status of the ApsaraDB for Redis instance and troubleshoot issues.
Metric granularity
To avoid adversely affecting the operation of the instance and ensure the effect of trend charts, metrics are collected at different frequencies and within different time ranges.
Supported time range | Data collection interval |
---|---|
10 minutes or less | 5 seconds |
More than 10 minutes and less than or equal to one day | 1 minute |
More than one day and less than or equal to seven days | 1 hour |
Note
- ApsaraDB for Redis allows you to query the monitoring data of the previous month. The maximum time range that you can specify for a query is seven days. For example, if the current day is March 10, 2021, you can query the monitoring data from February 10 to March 10. If you set the start time to February 10, the latest end time is February 17.
- If a cluster or read/write splitting instance has 32 or more data nodes, the time range that you can specify for all data nodes on the All tab cannot exceed 1 hour. The monitoring data is collected at intervals of 1 minute.
