Dear Experts,
 
  I've a windows service. If the service consumes more CPU utilization (say for instance 85% - which I could configure in config file and read in application) then I would like to restart the service. Could you please let me know how to achieve this?


Thanks.

You could throw an event that would tell the service to restart itself.  But then the question becomes, why is it consuming so much processor utilization?  Do you have an idea as to why your service does this?

Thanks. Some threads  are running for 2 days continuously. They are unmanaged threads. Hence could not identify the root cause of the issue. Please explain your solution how to achieve in code. Thanks.

Sure thing.  Let me throw a project together for illustrative purposes.

Here is a sample solution.  The solution itself, contains three projects:

1.  A service executable that is the ServiceFactory/ServiceBroker located in the EE_Q28570005 directory.
2.  A Common shared library in the Common directory.
3.  A SampleService library in the SampleService directory.

After you unzip this file, browse to the EE_Q2857005\Common\Resources directory and rename the file CommandLine.dll.zip to CommandLine.dll.

After you do this you can open the solution in VS2010 or higher.  Once you build the solution, the EE_Q28570005.exe file and the EE_Q28570005.Common.dll file can be placed into a directory on your system for testing.  The service contains an installer which can be initialized by starting a command prompt and running the command EE_Q28570005.exe -i.  To make the servicebroker listen for and start the sample service, you would use the command EE_Q28570005.exe -a SampleService.dll.  Note - These commands can be combined i.e. - EE_Q2857005.exe -i -a SampleService.dll.  A full list of command line options can be printed to the log file by simply typing EE_Q2857005.exe --help

The service broker also has a file watcher so once you drop the SampleService.dll into the directory that the service broker lives in, the SampleService will start.

SampleService would represent your current service.  SampleService contains an example ProcessorUtlization Event that is raised and that prints out a message to the log file.  Instead of printing out a message to the log file, you would utilize the service broker to stop and start (or restart) the SampleService.

Since the service broker uses a filewatcher, this also means that you can update your service (in this case SampleService) without needing to worry about stopping the service broker, you just inline replace the SampleService.dll with the updated version and the service broker stops the service and starts the code in the new version.
