B: Metric Alert with Dynamic Thresholds detection leverages advanced machine learning (ML) to learn metrics' historical behavior, identify patterns and anomalies that indicate possible service issues. It provides support of both a simple UI and operations at scale by allowing users to configure alert rules through the Azure Resource Manager API, in a fully automated manner.    A: You can use Azure Monitor to monitor base-level metrics and logs for most services in Azure. You can call Azure Automation runbooks by using action groups or by using classic alerts to automate tasks based on alerts.    Reference: https://docs.microsoft.com/en-us/azure/azure-monitor/platform/alerts-dynamic-thresholds   https://docs.microsoft.com/en-us/azure/automation/automation-create-alert-triggered-runbook

Box 1: readinessProbe: For containerized applications that serve traffic, you might want to verify that your container is ready to handle incoming requests. Azure Container Instances supports readiness probes to include configurations so that your container can't be accessed under certain conditions.    Incorrect Answers: livenessProbe: Containerized applications may run for extended periods of time, resulting in broken states that may need to be repaired by restarting the container. Azure Container Instances supports liveness probes so that you can configure your containers within your container group to restart if critical functionality is not working.  Box 2: periodSeconds: 15 The periodSeconds property designates the readiness command should execute every 15 seconds.    Reference: https://docs.microsoft.com/en-us/azure/container-instances/container-instances-readiness-probe

Box 1: Basic Assign Basic to users with a TFS CAL, with a Visual Studio Professional subscription, and to users for whom you are paying for Azure Boards & Repos in an organization.    Box 2: Stakeholder Assign Stakeholders to users with no license or subscriptions who need access to a limited set of features.    Note: You assign users or groups of users to one of the following access levels:   Basic: provides access to most features VS Enterprise: provides access to premium features Stakeholders: provides partial access, can be assigned to unlimited users for free   Reference: https://docs.microsoft.com/en-us/azure/devops/organizations/security/access-levels?view=vsts

E: Exceptions in your live web app are reported by Application Insights.   Note: Periodical reports help keep a team informed on how their business critical services are doing. Developers, DevOps/SRE teams, and their managers can be productive with automated reports reliably delivering insights without requiring everyone to sign in the portal. Such reports can also help identify gradual increases in latencies, load or failure rates that may not trigger any alert rules.    A: You can programmatically query Application Insights data to generate custom reports on a schedule. The following options can help you get started quickly: Automate reports with Microsoft Flow  Automate reports with Logic Apps    Reference: https://docs.microsoft.com/en-us/azure/azure-monitor/app/asp-net-exceptions   https://docs.microsoft.com/en-us/azure/azure-monitor/app/automate-custom-reports

The "Exploratory Testing" extension is now "Test & Feedback" and is now Generally Available.    Anyone can now test web apps and give feedback, all directly from the browser on any platform: Windows, Mac, or Linux. Available for Google Chrome and Mozilla Firefox (required version 50.0 or above) currently. Support for Microsoft Edge is in the pipeline and will be enabled once Edge moves to a Chromium-compatible web platform.    Reference: https://marketplace.visualstudio.com/items?itemName=ms.vss-exploratorytesting-web

1. Open Microsoft Azure Portal  2. Log into your Azure account and go to App Service and look under Monitoring then you will see Alert.  3. Select Add an alert rule  4. Configure the alert rule as per below and click Ok.  Source: Alert on Metrics Resource Group: az400-9940427-main Resource: az400-9940427-main Threshold: 5 Period: Over the last 5 minutes Webhook: https://contoso.com/notify             Reference: https://azure.microsoft.com/es-es/blog/webhooks-for-azure-alerts/

Service hooks let you run tasks on other services when events happen in your Azure DevOps projects. For example, create a card in Trello when a work item is created or send a push notification to your team's mobile devices when a build fails. You can also use service hooks in custom apps and services as a more efficient way to drive activities when events happen in your projects.    Note: Service hook publishers define a set of events. Subscriptions listen for the events and define actions to take based on the event. Subscriptions also target consumers, which are external services that can run their own actions, when an event occurs.    Reference: https://docs.microsoft.com/en-us/azure/devops/service-hooks/overview

Box 1: 5 minutes The alert must calculate the average once every minute.    Note: We [Microsoft] recommend choosing an Aggregation granularity (Period) that is larger than the Frequency of evaluation, to reduce the likelihood of missing the first evaluation of added time series    Box 2: Static   Box 3: Greater than   Example, say you have an App Service plan for your website. You want to monitor CPU usage on multiple instances running your web site/app. You can do that using a metric alert rule as follows: Target resource: myAppServicePlan Metric: Percentage CPU Condition Type: Static Dimensions  Instance = InstanceName1, InstanceName2  Time Aggregation: Average Period: Over the last 5 mins Frequency: 1 min Operator: GreaterThan Threshold: 70 Like before, this rule monitors if the average CPU usage for the last 5 minutes exceeds 70%.  Aggregation granularity    Reference:   https://docs.microsoft.com/en-us/azure/azure-monitor/platform/alerts-metric-overview

There are several tools available for running queries in Azure Data Explorer, including Kusto.    Kusto uses a role-based access control (RBAC) model, under which authenticated principals are mapped to roles, and get access according to the roles they're assigned.    Note: Azure Data Explorer is a highly scalable and secure analytics service that enables you to do rich exploration of structured and unstructured data for instant insights. Optimized for ad-hoc queries, Azure Data Explorer enables rich data exploration over raw, structured, and semi-structured data delivering fast time to insight. Query with a modern, intuitive query language that offers fast, ad-hoc, and advanced query capabilities over high-rate data volumes and varieties   Reference: https://docs.microsoft.com/en-us/azure/data-explorer/tools-integrations-overview
