Skill 5.1 Monitor Resources by using Azure Monitor Flashcards
What are areas to consider when creating a monitoring strategy
Visibility into services and the Azure Platform
Deeper Insights into applications
Resource Optimization
What does Azure Monitor do
maximizes the availability and performance of your applications by delivering a comprehensive solution for collection, analyzing, and acting on telemetry from your cloud and on-prem environments
Describe the Azure Monitor Landing Page
provides a jumping off point to configure other more specific monitoring services, such as Application insights, Network Watcher, Log analytics, Management solutiosn and so on
What is Azure Monitor for containers
offering for monitoring your Managed Kubernetes clusters (AKS) and Azure Container instances (ACI)
What are retention differences between Metrics and logs
Metrics are retained for 93 days
Logs can be retained for up to 2 years/
What are properties differences between logs and metrics
Metrics have a fixed set of properties which are time, type, resource, value, adn dimensions.
Logs have different properties for each log type
What are the data availability differences between logs and metrics
Metrics are gathered over time while logs are triggered by an event
Describe Log Analytics Workspace
allows the quering of data stored in log analytics and gives you access to the same query interfaces you have through Azure Monitor, but you can also make customizations to the configuration of the workspace and access workspace specific solutions
How long are guest OS metrics retained
Collected through diagnostic extensions and sent to an Azure Storage account.
Retained for 14 days
Guest OS metrics sent to Azure Monitor Metrics
Monitored Windows Diagnostic extentions of InfluxData Telegraf agent. Retained for 93 days
Describe Guest OS metrics collected by Log Analytics Agents
Collected by Log Analytics agent and are sent to a Log Analytics Workspace
Retention period of 31 days
Describe Application Insights log-based metrics
Log-based metrics that are translated into log queries. Retention period of 90 days
What are the properties that each metric has
-The time the value was created
-The type of measurement that value represents
-The resource with which the value is associated
- The value itself
Describe Log Analytics Workspace
where logs are collected and aggregated. The logs can alos be queried and visualized through log analytics or through azure mointor.
What needs to be provided to configure a workspace
-A name for the workspace
-The subscription the workspace will be associated with
-The resource group
- A location
- A selection for pricing tier
How much space is included with the free tier of workspace
5GB of logs a month
What must machines have to report logs to log analytics
Azure Log Analytics (OMS) agent which binds to a workspace to collect the data defined in the workspace settings
What are considered Diagnostic Logs
logs that you configure as a tenant service, or a resource are seperate from the Azure activity log and guest telemetry
Describe the Azure Activity Log
surfaces data at the subscription level and can be useful for understanding actions that occur within your environment against the Resource manager APIs. Events are retained for 90 days
What types of data can Azure Monitor store and surface
Metrics – Numerical Values such as performance counters
Logs – Either Numerical data or text
What language does Log Analytics use
Kusto Query Language (KQL)
How can Logs stored in Log analytics be removed from a workspace
Through the retention configuration
What can Alerts generated within Azure Monitor Invoke
Azure Automation runbooks,
Logic apps,
Azure functions, and even generate incidents in third-party IT service Management tools.
What are the components of a Alert Rule
A target resource
Conditional logic for the alert with criteria based on the available signals for the target resource
An Action Group, or what should happen when an alert rule condition is met
A name and description for the alert rule
What is the difference in Alert Rules in Azure Monitor and alerts
Alert rules in Azure Monitor is the criteria used when an alert should be generated. An alert is generated based on teh rule, and the alerts themselves are acted upon seperately
What actions can you run for action groups
Runbook – A set of powershell code that runs in the Azure Automation service
ITSM – You may have up to 10 IT service manager (ITSM) actions with an ITSM connection
Logic Apps – Provides a virtual designer to model and automate your process as a series of steps known as a workflow. There are many connectors across the cloud and on-premises on quickly integrate across services and protocols.
Webhook — A webhook allows you to route an Azure alert notification to other systems for post-processing or custom actions. For example, you cannot use a webhook on an alert to route it to sevices that send text, log bugs, or any number of other actions
How are alert rules managed
through Azure Mointor
How can alerts take to generate
10 minutes
What are the three states alerts can have
New – the alert is new and has not been reviewed
Acknowledged – The issues that generated teh alert is being actioned by teh administrator
Closed – the issue has been resolved
Describe applications insight
Used for development and as a production monitoring solution. It works by installing a package into your app, which can provide a more internal view of what’s going on with your code.
