 Each port configuration specifies whether it is a `suspend` or `nosuspend` port. Ports specifying `suspend` in their configuration will cause the runtime to pause early on in the startup path before most runtime subsystems have started. This allows any agent to receive a connection and properly setup before the application startup continues. Since multiple ports can individually request suspension, the `resume` command needs to be sent by each suspended port connection before the runtime resumes execution.

 Before we jump in head first, let's take a look at some basic methodologies as it relates to production diagnostics. When an outage occurs in production, typically the first and foremost goal is mitigation. Mitigation typically involves getting the app back up and running as quickly as possible. Common mitigation techniques involve restarting the app or sometimes one or more nodes/servers. While restarting is a quick and effective mitigation technique, root cause of the failure is still expected to be understood and appropriate fix(es) made to avoid future downtime. In order to get to root cause, we need to collect as much diagnostics data as we can prior to executing the mitigation strategy. The diagnostics data collected can then be analyzed postmortem to determine root cause and possible fixes. Each of the scenarios we will explore here will outline what capabilities .net core 3 has in terms of diagnostics data collection and analysis.

+# App is experiencing intermittent exceptions
+
+In this scenario, an ASP.NET application throws intermittent and sporadic exceptions making it challenging to use on demand dump generation tools to capture a dump precisely at the point of the exception being thrown. .NET has the capability to automatically generate dumps when an application exits as a result of an unhandled exception. However, in the case of ASP.NET the ASP.NET runtime catches all exceptions thrown to avoid the application exiting and as such we can't rely on the automatic core dump generation since an exception thrown never becomes unhandled. Fortunately, the Sysinternals ProcDump (v1.4+) for Linux allows you to generate dumps when the application throws any 1st chance exception.
+ProcDump for Linux download/installation instructions can be found here - [ProcDump for Linux](https://github.com/Sysinternals/ProcDump-for-Linux)
+
+
+For example, if we wanted to generate a core dump when an application throws a 1st chance exception, we can use the following:
+
+> ```bash
+> sudo procdump -e MyApp
+> ```
+
+If we wanted to specify which specific exception to generate a core dump on we can use the -f (filter) switch:
+
+> ```bash
+> sudo procdump -e -f System.InvalidOperationException MyApp
+> ```
+
+We can comma separate the list of exceptions in the exception filter.
+
+
+### Performance considerations
+
+ProcDump for Linux implements exception monitoring by using the profiler API. It attaches the profiler to the target process and waits for the exception notifications to arrive and if the filter is satisfied uses the .NET diagnostics pipe to instruct the runtime to generate a dump. Having a profiler attached to a process represents some amount of overhead but unless the application throws a large number of exceptions the overhead should be minimal.
