Simple Message Queue (SMQ, formerly MNS) provides a new set of monitoring metrics that can be used to collect data in a more fine-grained manner. The monitoring metrics also contain more metrics for key issue identification and troubleshooting. The latest version of Cloud Monitor ensures the timeliness and accuracy of the monitoring data. You can monitor data in a more efficient and convenient manner.
Usage notes
The new metrics is supported in regions such as China (Zhangjiakou), China (Chengdu), Thailand (Bangkok), and South Korea (Seoul). More regions will be supported in the future.
Log on to the Cloud Monitor console and choose in the left-side navigation pane. In the Middleware section of the Cloud Service Monitoring page, click Simple Message Queue(formerly MNS). On the page that appears, configure new alerts. The old entries Message Service - Queue and Message Service-Topic are removed from the the Cloud Monitor console.
