I am very new in Azure App Insights and accidently deleted an existing classic Smart Detection type alert. Is there a way to recover it?
AFAIK, We can not recover the Configuration of Deleted smart detection, Instead of that we have to create new alert rule with same configuration .
For more information Please refer this Microsoft Documentation : Smart Detection - Failure Anomalies & SO THREAD

I have .Net core App deployed on azure and enabled application insights.
Sometimes Azure application insights End-to-end transaction details do not display all telemetry.
Here it only logs the error and not request or maybe request logged but both do not display together over here(difficult to find out due to many people use it)
Should be like:
Sometimes request log but with no error log.
What could be the reason for happening this? do I need to look into application insights specific set-up/feature?
Edit:
As suggested by people here, try to disable the Sampling feature but still not works, Here is open question as well.
This usually happens due to sampling. By default, adaptive sampling is enabled in the ApplicationInsights.config which basically means that only a certain percentage of each telemetry item type (Event, Request, Dependency, Exception, etc.) is sent to Application insights. In your example probably one part of the end to end transaction got sent to the server, another part got sampled out. If you want, you can turn off sampling for specific types, or completely remove the
AdaptiveSamplingTelemetryProcessor
from the config which completely disables sampling. Bear in mind that this leads to higher ingestion traffic and higher costs.
You can also configure sampling in the code itself, if you prefer.
Please find here a good overview of how sampling works and can be configured.
This may be related to :
When using SDK 2.x, you have to track all events and send the telemetries to Application insights
When using auto-instrumentation with 3.x agent, in this case the agent collect automatically the traffic, logs ... and you have to pay attention to the sampling file applicationinsights.json where you can filter the events.
If you are using java, below the accepted Logging libraries :
-java.util.logging
-Log4j, which includes MDC properties
-SLF4J/Logback, which includes MDC properties
Is there a way (without actually keeping a state in a external application and scanning the configuration database) to detect a configuration change in BizTalk Server?
I know there are timestamps for changes for the different artifact in the configuration database but are there any sort of general flag that indicate a change?
I'd like to for example kick of a process as a change occurs and for example log current configuration - without adding triggers or similar things.
No, there is no 'change notification' built into the product nor is there an 'official' way to track or identify changes.
Of course, there are various techniques you can use to identify changes such as monitoring timestamps, examine the SQL Logs, etc, but that would be a custom implementation.
BizTalk 360 has a robust auditing feature that might cover what you're really asking for.
From experiance, this question of 'tracking changes' is driven by governance scenarios where controls and access are more open then they should be. That's a management problem.
I'm a nascent coder creating a simple iOS app. I'm experimenting with coding push notifications for the first time and I have a simple question regarding the Parse Installation Object and a scenario where multiple users log on the same device (let's say a loner iPad at a library).
Based on the Parse documentation I've seen, when a user subscribes to a channel - let's say "The Giants" - it saves this info on the Installation Object. But if the user logs out and another user logs in, does Parse assume that we are to erase the previous channels? Should channels therefore be saved to the User class first, and only saved to Installation when a user logs in? And similarly how do we handle advanced targeting where I want to query Installation for a specific User objectId? Is the best practice to always leave the last user logged in listed as 'owner'/'user'?
If you find the library example impractical, also consider something like signing into your Spotify account on a friend's device in order to play a private playlist at a party. I know these are less common scenarios, but I want to make sure I know how to handle them.
I'm new to Push Notifications so I may be missing something fundamental here, but if any experienced developer can lend some advice as to how they handle this scenario, it would be greatly appreciated.
Store a reference to PFUsers when you save the installation. Add a field #"owner" and tag the pfuser to it.
After a user logs in, if they are not associated with the current installation, send an alert asking if they'd like to receive pushes on this device. If that's the case, resave and update the current installation. Otherwise leave it as is.
This is a tricky area, let me know what you come up with.
It's pretty rare that people will sign onto a service using someone else's phone, so I don't think its a huge issue if you want to just "see what happens" and if there's demand work it out.
I have 3 iOS apps using a single Parse application which supports push notifications for all 3 apps. I have a flag set on the project for the Release configuration for NDEBUG. I use #ifndef NDEBUG to set the boolean on a value I set on the current installation. This way it makes it easy to identify which installation that I can use for testing push notifications. I also use the appIdentifier value to filter to the application I am testing.
I also set other values as needed but these values are a good start.
if (debug) {
[currentInstallation setObject:[NSNumber numberWithBool:YES] forKey:#"debug"];
}
else {
[currentInstallation setObject:[NSNumber numberWithBool:NO] forKey:#"debug"];
}
Hi
I've downloaded the Cairngorm3 Simple Sample Application from here.
There's a few steps.
a) Download the server-side zip. It contains a PDF instructing how to start a HSQLDB database and get a Tomcat instance up an running (I used catalina.sh start).
b) Check out the source with Subversion, and load it up into Flashbuilder 4. (You need Flex 3.4 SDK)
When I run the app (an Outlook like app written in Flex), I have issues at the point I try and save a contact. I'm assuming it's on a remoteobject call.
But it I get this:
Send failed
faultCode:Client.Error.MessageSend faultString:'Send failed' faultDetail:'Channel.Ping.Failed error Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly. url: 'http://localhost:8400/messagebroker/amf;jsessionid=5765DDDB6E2D54BD03D3E636B0E8C03E'''
I'm wondering if this is something you need to tweak in services-config.xml?
Located in flex-frameworks/tomcat/webapps/ROOT/WEB-INF/flex folder (flex-frameworks comes from the server-side zip download:
Anyone got any ideas?
This is Christophe Coenraets baby.
I also subsequently found a blog post by Alexander Glosband, but couldn't ascertain from it, what you need to do as a work around. i.e. Is this something that is configurable?
The way to reproduce the error consistently is to try and activate the web camera from the app. Then instead of clicking accept, reload the screen. Then when you try and take a photo after subsequently granting access to camera, you get the duplicate session error.
I think there is an issue with the code pertaining to the Camera, that's not cleaning up after itself correctly, the session is probably not being tidied up correctly.
You are right, problem comes from services-config.xml. Change your url from
http://localhost:8400/messagebroker/amf
to
/messagebroker/amf
I found solution from here send failed error

I need to design a bug alert system, where the web support team is notified via email when a user of our website encounters an error of any sort (database exception, or a 404)
What would be the best way to design this section of the project? Any ideas would be appreciated.
You may want to look into using the global.asax file for application-wide error intercepting. A quick search yields this step-by-step walk-through:
http://aspnetresources.com/articles/CustomErrorPages.aspx
Depending on the volume of traffic you're expecting, sending an e-mail every time an error is intercepted may not be the best approach. At best, you'd flood inboxes (and make the support staff very unhappy), and at worst you'd get your mail servers blacklisted for spamming. The approach that I've used in the past on high-traffic sites is to queue up errors in a table that is read and purged at a set interval by a separate process. The process would aggregate the errors, grouping them by type, number of occurrences, etc, then send out an e-mail report to the support mailing lists.
ASP.NET health monitoring may be of interest: http://msdn.microsoft.com/en-us/library/ms998306.aspx. It's really simpler to use than this article first appears and doesn't require any additional components - it's all built-in.
I would implement an HTTPmodule that captures the onError event.
This is would allow the module to be reused over multiple applications. The destination email addresses, SMTP server etc, could be in the HTTPmodule, overriden in the web.config file for maximum flexibility.
