Overview: Azure Dashboards are excellent but, if you want beautiful dashboards use the Azure Grafana service or Power BI dashboards.

It's always difficult to identify KPI's and graphs to allow support and stakeholders to quickly digest monitoring information.  An option is to have an overview for the PM, PO, Business owners,,, and a separate set of dashboards for support.

Identify What is important?  End-to-end testing is always nice especially if running CI to detect abnormalities.

For instance, this Azure Dashboard, fires of a Canvas App recorded Test (done using test studio) and shows the speed (performance) of the run, i then warn the user if the performance is too slow.  I also grab the oldest successful run from 7 days ago to check if performance is considerably different.  

Power automate has it's own logging, but integrating log entries when a error occurs via Log analytics, allows me to see if any of my workflows have a problem.  This is discussed in part 6 of the logging series on Flows.

Azure services are often used when building solutions using the Power Platform.  The most common are Functions, App Services, APIM, Service Bus, maybe sendgrid.  So we need to know that they are working, and help the user see performance or issues.  Here are a couple of examples.

Logging and Monitoring Advanced Canvas Apps

Overview: Most Canvas apps reach back to 3rd parties or internal storage e.g. SQL, Dataverse, blobs to persist data.  In an ideal world we want to be able to identify error and performance concerns and be able to trace quickly.

Scenario: A canvas app performs a search against a custom connector, that goes to an external API, for example search's for Company Numbers from an Open API.

  • The annotated diagram, in orange records the button pressed to run the search.  This only shows if the "Upcoming feature", "Enable Azure Application Insights correlation tracing" is enabled.
  • A custom connector, in blue, makes  a call to an REST/Open API.
  • The last call is to an external API, highlighted in purple, (in this case it was actually a mocked APIM endpoint, but the icon would change it it was totally external such as call API search to the IRS, HMRC, Inland Revenue.

Tip: Always create App Insight Instances using a workspace and not the classic-mode app insights as it is being deprecated by Microsoft in early 2024.

App Insights Understanding:

App Insights setup using the Workspace-based setup (Log Analytics) can be queried in two ways:

  • Query thru App Insights
  • Query thru the Log Analytics workspace (the Kusto/KQL is slightly different, but it's rather minor)

Tip: If you upgrade from classic to the workspace base app Insights, the log history is still "query-able" as App Insights combines the logs from AppInsights Classic (stored in app insights directly) and the logs stored in Log Analytics.

Tip: Power Automate has a connector to Log Analytics so it's good to use this for flows so you can trace canvas apps using flow journeys.  Most people tend to build a custom connector to a function that uses the AppInsights SDK.  I've used both and they are both valid approaches and shown in the annotated diagram below.

The two options for logging Flows into App Insights.

Note: If you create a new App Insights workspace-based instance remember to update the loggers in all you Azure Services to the new instance (app key).  For example functions, APIM and Service Bus are common components.

Note: You can log to multiple workspace/app insights in a tenant and the correlations will be retrieved so you see the full history, assuming you have permissions to all log sources.

Learning: the instrumentation key for app insights has 3 parts to it: 
1) instrumentation key (basically a unique identified to find and allow logs to be saved into AppInsights, 
2) ingestion endpoint (URL for the log), and 
3) monitoring metric endpoint (URL for metrics/performance counters/live metrics/failed requests/). 

Here is an example and you can see the 3 parts:
InstrumentationKey=2675bxxx-xxxb-xxxx-bf5558009ccf;IngestionEndpoint=https://uksouth-1.in.applicationinsights.azure.com/;LiveEndpoint=https://uksouth.livediagnostics.monitor.azure.com/

Power Platform Logging, Monitoring, and Alerting

This post relates to a previous strategy blog post, read that first https://www.pbeck.co.uk/2023/02/setting-up-azure-application-insights.html

Overview:  Microsoft uses Azure Application Insights to natively monitor Power Apps using an instrumentation key at the app level.  To log for model driven apps and Dataverse this is a Power Platform config at the environment level e.g. UAT, Prod.

When setting up Application Insights, use the Log Analytics workspace approach and not the "Classic" option as this is being deprecated.

Power Apps (Canvas Apps): Always add the instrumentation key to all canvas apps, it is set in the "App" level within each canvas app.  Deploy solutions brings challenges with changing keys for app insights logging (unmanaged layers).

"Enable correlation tracing" feature imo. should always be turned on, it is still an experimental feature but with it off, the logging is based on a sessionid

"Pass errors to Azure Application Insights" is also an experimental feature.  Consider turning it on.

Canvas Apps have "Monitor", Model driven apps also have this ability to monitor, and Power automate has it's own monitoring

Log to App Insights (put app insights on Azure Log analytics), simple example with customDimensions/record.

Trace("My PB app ... TaxAPI.NinoSearch Error - Search - btnABC",
        TraceSeverity.Error, // use the appropriate tracing level
        {
            myappName: $"PB App: {gblTheme.AppName}",
            myappError: FirstError.Message,  // optional
            myappEnvironment: gblEnv,
            myappErrorCode: 10010,
            myappCorrelationId: GUID() // unique correlationId
        }
    );
Query the logs using kusto:
traces
| extend errCode = tostring(customDimensions["myappErrorCode"]), err = tostring(customDimensions["myappError"])
| where errCode == "100100"

Push cloud flow execution data into Application Insights | Microsoft Learn

Allows logging to tie Flows back to the calling Canvas app.  You can now do this manually but it has to be applied at all calls to or after the flow.

Below is a basic checklist of decisions to ensure you have suitable logging

Logging Checklist:

  1. Setup Azure Log Analytics (1 per DTAP env e.g. uat, prd)
  2. Get the workspace key needed for logging to Log analytics "Agents" > "Log Analytics agent instructions", copy the Workspace Id and the Secondary Key
  3. Create an Azure Application Insights per DTAP
  4. Each Canvas app needs an instrumentation key (check, have you aligned DTAP log instances with the Canvas App DTAP)
  5. Power Automate has great monitoring, but it is a good idea to setup logging for Dataverse (which shall cover model apps), done thru Power Platform Admin Studio > Environment
  6. Enable Logging Preview Feature for Canvas apps & check the power automate push cloud execution feature state.
  7. Do you have logging patterns in you Canvas app for errors, do you add tracing, and is it applied consistently?
  8. Do you have a Pattern for Power Automate runs from Canvas apps?  I like to log if the workflow errors after the call.
  9. Do you have a Pattern for Custom Connectors?
  10. Do you correlation trace Custom API (internal and 3rd party)? 
  11. Do you have a Try, Catch, Finally scope/pattern for Workflows.  How do you write to the logs, most common is to use an Azure Function with the C# SDK.  I like to use the Azure Log Analytics Connector in my catch scope to push error info into the workspace log using a custom table.
  12. Ensure all Azure Services have instrumentation keys. Common examples are Azure Functions, Azure Service Bus, API Manager, the list goes on...
  13. Do you implement custom APIM monitoring configuration?
  14. Do you use the SDK in your code (Functions etc.)?
  15. Setup Availability tests - super useful for 3rd party API's.

Once you have the logs captured and traceable (Monitor & Alerting Checklist):

  1. Create Queries to help find data
  2. Create monitoring dashboard using the data
  3. Use OOTB monitoring for Azure and the platform
  4. Consider linking/embedding to other monitors i.e. Power Automate, DevOps, Postman Monitor
  5. Setup alerting within the Azure Log Workspace using groups, don't over email.  For information alerts, send to Slack or Teams (very simple to setup a webhook or incoming email on a channel to monitor)
  6. Power Automate has connectors for adaptive cards channel messaging, consider using directly in Flows or from alerts, push the data into a flow that will log the alert using an adaptive card right into the monitoring channel.

App Insights Overview for SaaS logging and tracing

Overview:  App Insights provides independent infrastructure for logging and tracing activities.  It is tightly coupled with Azure services including PaaS.  This allows for consistent scalable logging.  App Insights now stores logs in Azure Log Analytics, these are all under the umbrella of Azure Monitor, 

On a SaaS solution, I am looking for App Insights to log any errors have the ability to log trace information.  I want a unique correlationId (to allow for distributed tracing) on the front end if there is an error so support can identify the exact issue/transactions.  A unique correlationId in the http header allows for identifying a transaction and this is useful for tracing and performance monitoring.  Using the App Insights SDK's and implementing a common logging module is a good idea.  There are two common areas that need call out to ensure the ability to trace transactions:

  1. SPA's (Requirement to generate a unique operation/correlationId per operation not per pageview), and
  2. Long running operation such as timer jobs or service bus calls.

Support & DevOps:

Having a correlationId allows first line to log the correlationId and quickly follow the request without asking for replication steps.  This context tracing approach is common on newer applications. Third line support has full traceability of an issue to support who can empirically see the perceived performance parts broken down using the correlationId in the header.

Key API's can be continuously monitored for errors and slow down in performance, alerts can be configured around this monitoring. 

Building a first line support tool that displays the errors in a hierarchy, has help scripts and knowledge bases is a good option for streamlining support.

App Insights has live monitoring and also has Kusto query language is useful for monitoring specific queries.

Monitoring:  Azure dashboards are great for monitoring application health and performance.  Easy to customise, make unique dashboards and security is easy to control.  sentry.io monitors API's, I have not used it.  I like all the Azure stuff coming out for testing and I feel continuously running Postman collections and reporting to App Insights is the best way to go.  Azure Dashboards can be limiting, Azure Grafana can be a great alternative/enhancement.  Check out Azure Managed Grafana.

Alerting: I all to often see an overuse of alerting resulting in recipients ignoring a plethora of emails.  I believe in minimising alerts especially via email, and SMS type messaging.  For me, I like to create a dedicate channel for alerting that includes all DevOps members and either notify via a Teams card, and even easier is to email the channel.  This can be broken down further but to start I create a channel for alerting for each DTAP environment.

Note: The default channel setup only allows members of the teams channel to send email so the alerts from Azure monitor using rules won't be accepted.  On the channel, and admin needs to go to the "advance settings" and change the option from "Only members of this Team" and change it the setting to "Anyone can send".

Options:  There are great services for logging so my default tends to be Azure Monitor.  The main players in Application & API observability and monitoring include: 

  • Microsoft: Azure Monitor includes Application Insights & Azure Log Analytics
  • Dynatrace (really good if you use multicloud) or Dynatrace AWS cloudwatch,  Dynatrace - Saas offering is on AWS.  Can be on-prem.  OneAgent is deployed on the Compute i.e. VM, Kubernetes.  Can import logs from other SIEMs or Azure Monitor, so you can eventually get Azure service logs such as App Service or Service Bus.  Does Full stack and includes code-level and applications and infrastructure monitoring, also can show User monitoring.  Dynatrace offers scalable API's that are sitting on Kubernetes.  "Davis" is the AI engine used to help figure out the problems.  Alerting is solid.
