Public preview: Person vs platform dimension launched for VM availability metric
Many shoppers have emphasised the necessity for user-friendly monitoring options that present real-time, scalable entry to compute useful resource availability information. This data is important for triggering well timed mitigation actions in response to availability adjustments.
Designed to fulfill this crucial want, the VM availability metric is well-suited for monitoring traits, aggregating platform metrics (equivalent to CPU and disk utilization), and configuring exact threshold-based alerts. You’ll be able to make the most of this out-of-the-box VM availability metric in Azure Monitor.
Now you should utilize the Context dimension to determine whether or not VM availability was influenced by Azure or user-orchestrated exercise. This dimension signifies, throughout any disruption or when the metric drops to zero, whether or not the trigger was platform-triggered or user-driven. It could assume values of Platform, Buyer, or Unknown.
The brand new dimension can be supported in Azure Monitor alert guidelines as a part of the filtering course of.
Public preview: Allow sending well being sources occasions to Azure Monitor alerts in Occasion Grid
Azure Occasion Grid is a extremely scalable, totally managed Pub/Sub message distribution service that provides versatile message consumption patterns. Occasion Grid lets you publish and subscribe to messages to help Web of Issues (IoT) options. By HTTP, Occasion Grid lets you construct event-driven options, the place a writer service (equivalent to Venture Flash) broadcasts its system state adjustments (occasions) to subscriber functions.
With the combination of Azure Monitor alerts as a brand new occasion handler, now you can obtain low-latency notifications—equivalent to VM availability adjustments and detailed annotations—by way of SMS, e-mail, push notifications, and extra. This combines Occasion Grid’s close to real-time supply with Azure Monitor’s direct alerting capabilities.
To get began, merely observe the step-by-step directions and start receiving real-time alerts with Flash’s new providing.
