Azure Helps to Creating Log Searches And Raising Of Alerts
Alerts in Azure Monitor can identify important information in your Log Analytics repository. They are created by alert rules that automatically run log searches at regular intervals, and if results of the log search match particular criteria, then an alert record is created and it can be configured to perform an automated response.
Application Log Alerts
Azure supports application-level logging into two main destinations: Application Insights (which we discussed in part 2 of this series) and Azure Monitor’s own log management system. Both of these services receive log entries, store and index them within a few minutes, and allow for interactive querying through a powerful syntax called KQL. Additionally, we can create scheduled log query alert rules that run on the log data.
Microsoft recently announced that they have renamed the service previously known as Log Analytics to Azure Monitor logs.
Scheduled log query alert rules are relatively simple: at a frequency that we specify, they run a defined query and then look at the result. If the result matches criteria that we have specified then an alert is fired.
Like metric alert rules, scheduled log alert rules specify the conditions under which an alert should fire, but they don’t specify the process by which a human or system should be notified.
Metric Log Alerts
There is also a special scenario available: when certain log data gets ingested into Azure Monitor logs workspaces, it is made available for metric alerting. These alerts are for data including performance counters from virtual machines and certain other types of well-known log data. In these cases, logs are used to transmit the data but it is fundamentally a metric, so this feature of Azure Monitor exposes it as such.
Activity Log Alerts
Azure’s activity log is populated by Azure automatically. It includes a number of different types of data, including resource-level operations (e.g. resource creation, modification, and deletion), service health data (e.g. when a maintenance event is planned for a virtual machine), and a variety of other types of log data that can be specific to individual resource types.
Service Health Alerts
Azure provides service health events to advise of expected as well as unexpected issues with Azure services. For example, when virtual machines have a maintenance window scheduled, Azure publishes a service health event to notify you of this fact. Similarly, if Azure had a problem with a particular service (e.g. Azure Storage), it would typically publish a service health event to advise of the incident details, often both during the incident and after the incident has been resolved.
Resource Health Alerts
Azure also helps to filter the relevant service health events into another category of activity log event, using the ResourceHealth category. While service health events provide information about planned maintenance and incidents that may affect entire Azure services, resource health events are specific to your particular resource. They essentially filter and collapse service health events into a single health status for a given resource. Once again, Microsoft provide an example ARM template within their documentation.
Azure Sentinel Service
A powerful feature of the Azure Sentinel service is the ability to ingest data from a variety of sources. The connector also allows you to ingest data from locations other than Azure, giving you a more complete picture of the security status of the entire service in your technical landscape.
EXPERTISE At Dalwax, we’ve tackled several challenging Azure transformation journeys for our customers, by re-architecting and rewriting their applications from the ground up to be Azure-native. Along the way, we learned some key lessons on how to re-architect applications to be modular, scalable, fault tolerant and ultra-responsive.
PaaS & Container Architectures
We are experts at converting traditional stateful applications into modern applications leveraging Azure PaaS services and container architectures for total control over scalability and resilience.
While modernizing applications we leverage an Agile DevOps driven approach that enables application delivery transformation by enabling toolchains and processes that support continuous integration and continuous delivery.
We can help develop and implement best-fit architectures and components depending on whether your application is heavy on end-user interactions (predominantly user driven and UI / UX is important) vs Event driven (IoT and business process automation Intelligent apps).
Corporate compliance, governance and performance considerations can mandate application components to remain within Private cloud or existing on-premise environments, and still talk to the Public cloud components. Our experts can help design solutions for optimal performance and scale.
While monolithic, on-premise applications are perceived to be secure due to the ability to implement centralized security policies while behind corporate firewalls, with our knowledge and expertise we can help deploy enhanced security postures within your Azure cloud environments.
We can help businesses efficiently leverage ready-to-use Azure cloud services and solution components to reduce development time while benefitting from the inherent cloud native features of the services. Our experts strike the right balance between upfront vs ongoing benefits of using these services.
