You can use the Log Analytics agent for Linux as part of a solution to collect JSON output from the Linux virtual machines.

The Azure Custom Script Extension is used for post-deployment configuration, software installation, or any other configuration or management task.

Desired State Configuration (DSC) is a management platform that you can use to manage an IT and development infrastructure with configuration as code.

The Azure VMAccess extension acts as a KVM switch that allows you to access the console to reset access to Linux or perform disk-level maintenance.

Azure Monitor Alerts State#

The alert state is manually set by the user and does not have any automated logic behind it. The alert state can be either New, Acknowledged, or Closed.

Use Recovery Services vaults to hold backup data for VMs and SQL Servers. By default, backups of virtual machines are kept for 30 days.

The Microsoft Azure Recovery Service (MARS) agent is mandatory to be installed on the servers to perform backup and recovery services.

Azure Monitor alerts can be used for metrics, logs, and the activity log. Different types of alerts have benefits and drawbacks. Metrics is a feature of Azure Monitor that collects numeric data from monitored resources into a time-series database. Metrics are numerical values that are collected at regular intervals and describe some aspect of a system at a particular time.

When Azure Monitor data indicates that there may be an issue with an infrastructure or application, an alert is triggered. Azure Monitor, Azure Service Health, and Azure Advisor then use action groups to notify users about the alert and take action. An action group is a collection of notification preferences defined by the owner of an Azure subscription.

If using SMS as trigger to alerts a maximum of one SMS message can be sent every five minutes.

For guest users, the user principal name (UPN) will contain the email of the guest user (bsmith_contoso.com) followed by #EXT# followed by the domain name of the tenant (@fabrikam.com). Regular Microsoft Entra users appear in a format of user@fabrikam.com. Ex: UserPrincipalName: bsmith_contoso.com#EXT#@fabrikam.com
