To improve user experience, ApsaraDB for MongoDB adjusts the method used to collect the IOPS data of instances that use enhanced SSDs (ESSDs) on January 11, 2024. IOPS-specific monitoring data may fluctuate during the adjustment, which does not affect the running of the instances.MongoDB
Adjustment date
January 11, 2024
Applicable scope
MongoDB instances that use ESSDs to store data.
Content
ApsaraDB for MongoDB adjusts the method used to collect the IOPS statistics of instances that use ESSDs on January 11, 2024. After the adjustment, the logic for collecting IOPS data takes into account the impact of buffers. This way, you can retrieve the IOPS performance of the instances in a more accurate manner and identify and troubleshoot exceptions in a timely manner.
The following IOPS-specific metrics are involved in the adjustment:
data_iops: the IOPS utilization of data disks.
log_iops: the IOPS utilization of log disks.
iops_usage: IOPS usage (the ratio of the IOPS used by an instance to the maximum available IOPS)
Impacts
For ApsaraDB for MongoDB instances that use ESSDs, IOPS-specific metrics (data_iops, log_iops, and iops_usage) in monitoring information described in Basic monitoring, Subscribe to event notifications, and CloudDBA for performance diagnostics and optimization may experience fluctuations. If these metrics exceed the specified alert threshold, an alert notification is triggered. The fluctuation does not affect the running of these instances.
