View all details for a single web request (transaction trace) Some other APM solutions, like Retrace, also support MongoDB, RavenDB, Elasticsearch, Redis, Memcached, AppFabric, MSMQ, NServiceBus, AWS services and more. LimitationsĪpp Insights does not support some other notable key Azure dependencies include Service Bus and redis. Anything else requires using their SDK to manually track each dependency call. Microsoft’s documentation says SQL databases, HTTP calls, and Azure storage libraries are supported. ☹Īpp Insights supports tracking dependency calls in your code. It does see it, it just doesn’t associate it with the ASP.NET web request. Return Request.CreateResponse(HttpStatusCode.OK, data) Īpp Insights does pick up the 2 logging messages via log4net, but doesn’t show anything for dependency calls. Log.Debug('Completed HttpClient.GetStringAsync()') Log.Debug('Starting HttpClient.GetStringAsync()') Unfortunately, it does not support the recommended way to make HTTP calls with ASP.NET. Asynchronous HttpClient calls are not supportedĪlmost all new ASP.NET development is now done in async and uses the common async/await pattern.

Retrace can collect all exceptions, including first chance exceptions, with no code changes.

No way to collect all “first chance” exceptions.

Some other APM solutions don’t require any code or config changes to collect unhandled exceptions.

No way to see exceptions across all applications.

App Insights has no reporting across apps to easily see this. If you are having SQL timeouts, for example, odds are they impact multiple applications. Limitations and missing exceptions featuresĪpp Insights is missing some key features around exceptions.

Manually report exceptions via their SDK if needed.

If you use log4net, NLog, etc you can configure it to send your exceptions.

Modify code to collect unhandled exceptions for MVC, global.asax, etc.

To ensure that all of your exceptions are collected you must install their SDK and make some code and config changes. 6. View top exceptions in your applicationĪpplication Insights has good reporting to group application exceptions so you can uniquely see which ones are occurring and how often.

I specifically noticed full SQL queries were not collected without it. App Insights will seem to work, but there are some things that don’t work until you install the site extension. You can add Application Insights to your project and deploy it to Azure as an App Service.

Look for missing gaps of time in your requests. A simple query that selects a lot of data may show that it didn’t take very long at all, but may have taken a lot more time to actually download the query results.Ī simple example of of a query that took 83 milliseconds, but it took another 60 to download and iterate the results. Only the amount of time to execute the query on the server is included in the timings. If you are using SQL Azure it has some built in tuning advisor functions for this too. To get a list of slow SQL queries, you would need to query SQL Server’s DMVs or use a different APM solution. There is also no way to set up monitoring for a specific SQL query. There is no to see how long individual queries take, which is the slowest or being called the most often. Key limitation: Finding slow SQL queriesĪpplication Insights provides reporting down to the server and database name being accessed. This means if the query contained personal information, credit card numbers, or anything else that could be sensitive, it is getting uploaded from your server to Microsoft.Īnother thing to know on this topic, App Insights never collects SQL parameters. If your code uses dynamic SQL, Application Insights will collect the full query and upload it to Azure. Warning! Sensitive data is not scrubbed from dynamic SQL queries App Insights does not support 2.0 and they don’t have any plans to do so.

I know it sounds crazy, but you wouldn’t believe how many people have older apps written in 2.0 that they still have to support and have never been upgraded.

App Insights will work with 4.5 or newer but 4.6 is preferred.

Be sure to update your app and redeploy it. NET framework that enables some additional data collection abilities. There are some changes in the 4.6 version of the.
