Understanding heartbeat in ASP.NET health monitoring

痴心易碎 提交于 2019-12-07 15:00:39
问题 Who's triggering the event? What are consequences/benefits of enabling it in <healthMonitoring enabled="true" heartbeatInterval="30"> except it appears every 30 seconds in the logs? Has it anything to do with NLB heartbeat? What interval is better for production use? 回答1: Enabling it in this way in the web.config will cause the Application Domain to raise a WebHeartbeatEvent periodically (in your case every 30 seconds), basically to check if your application is 'still alive' (like checking a

C# Roslyn change type of comment

问题 I'm trying to make an extension for Visual Studio that changes some syntax in the code. Actually, I've done the first step which was to change the name of a variable if this name was not okey with the rules we use in the firm. For example: int newVariable; double test; will be changed into: int iNewVariable; double dblTest; Now I have to change this type of comment: (SingleLineComment) //this is a single line Comment Into a MultiLineComment /*Here it's a MultiLine one*/ I use the Roslyn

我怕爱的太早我们不能终老 提交于 2019-12-06 05:16:44
问题 I would Like to enable Diagnostic (DIAG) Mode on Android. I have the following questions about the same. How is DIAG mode helpful ? Is Rooting the Device necessary to enable DIAG Mode ? How to verify if DIAG mode is enabled ? Is it reversible ? Can i go back to Normal Mode ? I'm using Google Nexus 5. I'm fairly new to Android Development. Any help would be appreciated. 回答1: 1- I personally use DM to collect and analyse the messages between a mobile (UE) and a network. I use it with Qualcomm

GCC's two unusual error messages

六月ゝ 毕业季﹏ 提交于 2019-12-05 23:18:51
Today, I came across two error messages which I never seen before. It's completely new to me. Here is the code: template<typename T> struct adder { adder(const T &item) { } }; template<typename T> void initializer(const T &item) { adder<T>(item); } int main() { initializer("const string literal"); } On compiling, GCC gives these errors: prog.cpp: In function ‘void initializer(const T&)’: prog.cpp:6: error: declaration of ‘adder<T> item’ shadows a parameter prog.cpp: In function ‘void initializer(const T&) [with T = char [21]]’: prog.cpp:10: instantiated from here prog.cpp:6: error: declaration

How to use GCC diagnostic pragma with C++ template functions?

拟墨画扇 提交于 2019-12-05 01:32:03
问题 I would like to use g++ and -Werror , so I have now to disable warnings for 3rd-party libraries I have no control of. The solution provided by http://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Pragmas.html works very well, allowing simply to wrap the includes of 3rd party headers with pragmas. Unfortunately, that did no longer work for me in a certain setup where templates are involved. I created the following minimal example of where this approach did not work as expected: Source file main.cpp

How to identify the caller of a Stored Procedure from within the Sproc

随声附和 提交于 2019-12-04 17:56:19
问题 I have a deprecated stored procedure which should no longer be called from code, but there is some system which is still calling it. This is a production server so I have very limited indirect access to it for performing diagnostics. Is there any way to determine the machine which is calling a particular stored procedure from within the sproc? Something such as @@CallingMachineIP or @@CallingMachineName 回答1: select hostname from master..sysprocesses where spid=@@SPID or select host_name from

What's the right statistic for iOS Memory footprint. Live Bytes? Real Memory? Other?

爱⌒轻易说出口 提交于 2019-12-04 07:41:15
问题 I'm definitely confused on this point. I have an iPad application that shows 'Live Bytes' usage of 6-12mb in the object allocation instrument. If I pull up the memory monitor or activity monitor, the 'Real Memory' Column consistently climbs to around 80-90mb after some serious usage. So do I have a normal memory footprint or a high one? This answer and this answer claim you should watch 'Live Bytes' as the 'Real Memory' column shows memory blocks that have been released, but the OS hasn't yet
